Description

Technical Field

[0001] The present invention relates to the technical field of forming a rotating body structural part, and in particular to a method for preparing a rotating body structural part. Background Art

[0002] Many aircraft have numerous rotating parts, such as cylinders, hollow shafts, and rings. Many rotating structures have internal and external ribs, such as ribbed cylinders, which can be used in missile and rocket cylinders, aircraft nose cones, and the like. Some rotating structures have connecting joints at both ends, such as drive shafts, which can be used as aircraft truss structures, achieving both load-bearing and deformation. Some rotating structures have outer ring blade structures, such as integral blade rings, which are used in the compressors of high thrust-to-weight ratio engines. The materials used to manufacture rotating parts can be a single alloy material, a composite of multiple alloy materials, or a fiber-reinforced metal matrix composite material. Conventional methods for preparing metal rotating structural parts mainly include extrusion, forging, rolling (including wedge cross rolling), casting, spinning, powder forming, and additive manufacturing. Additive manufacturing methods mainly include wire arc additive manufacturing (WAAM), electron beam free form fabrication (EBFM), and laser directed deposition (LENS). The methods used to manufacture continuous fiber reinforced metal matrix composites mainly include foil-fiber-foil method, matrix coating method, powder cloth method, liquid impregnation method, pressure casting method and plasma spraying method.

[0003] When forging or extruding are used to prepare rotating structural parts, a solid cylindrical preform must first be formed, followed by CNC machining. This involves large CNC machining workloads, long manufacturing cycles, low material utilization, and high manufacturing costs. Casting yields a cast structure with limited performance, and the thin-walled, high-ribbed strips are limited by material fluidity, so the wall thickness cannot be too thin. Powder metallurgy, after hot isostatic pressing, has numerous gaps and interfaces between the powders, resulting in a certain porosity even after high-temperature, high-pressure compounding, resulting in limited performance. Spinning, for titanium alloy thin-walled, high-ribbed strips, requires the production of a segmented spinning die. Furthermore, thin-walled, high-ribbed strips are difficult to form, with the taller the strips and the thinner the wall thickness, the more difficult they are to form. Additive manufacturing, generally requiring cladding of the metal material, can easily produce metallurgical defects such as pores, cracks, lack of fusion, and segregation in the microstructure of the formed part, leading to insufficient performance. When preparing continuous fiber-reinforced metal matrix composites using the foil-fiber-foil method, the fibers are prone to movement during the subsequent hot isostatic pressing (HIP) process, resulting in uneven fiber distribution. Furthermore, the fiber percentage of the prepared composite cannot be too high, otherwise it will cause fiber damage. The main method for preparing continuous fiber-reinforced metal matrix composites using the matrix coating method is physical vapor deposition (PVD), including magnetron sputtering, triode sputtering, and electron beam PVD. However, these methods have low preparation efficiency, especially magnetron sputtering PVD, which generally takes between 8 and 36 hours. Furthermore, the material utilization rate is very low, generally less than 3% or even less than 1%, making the manufacturing cost very high. When preparing continuous fiber-reinforced metal matrix composites using the powder coating method, the powder easily absorbs oxygen and hydrogen during the preparation process, introducing impurities into the part, resulting in insufficient performance of the prepared composite. Furthermore, during HIP, it is difficult to fully densify the powder, and the formed part has a certain amount of porosity. The plasma spraying method is used to prepare continuous fiber-reinforced metal matrix composites. During plasma spraying, the fiber surface is easily damaged, resulting in a decrease in the performance of the composite material. The pressure casting method is used to prepare continuous fiber-reinforced metal matrix composites. It is necessary to first prepare a fiber preform and place it in a mold. Then, under high temperature conditions, liquid metal is immersed into the gaps in the fiber preform using air pressure or mold pressure. Since the matrix metal is in a high-temperature molten state, it will react with the fiber preform at the interface. Sometimes, even when the pressure casting time is relatively short, a violent interfacial reaction will occur, which will directly affect the performance of the composite material. Excessive pressure in extrusion casting will also cause the fiber preform to collapse and deform, affecting the distribution of fibers in the composite material and resulting in insufficient performance of the composite material.

[0004] Therefore, the inventor provides a method for preparing a rotating body structural member. Summary of the Invention

The detailed description of the following embodiments and the accompanying drawings are intended to illustrate the principles of the present invention and are not intended to limit the scope of the present invention.

[0048] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] Figure 1 is a schematic flow chart of a method for preparing a rotating body structure provided by an embodiment of the present invention, such as Figure 1 As shown, the method may include the following steps:

[0050] S101. Passing metal and continuous fiber monofilaments / single tapes through a suspended melting crucible to prepare monofilaments or single tapes; wherein the order of the metal and continuous fiber monofilaments / single tapes is metal monofilaments / single tapes, continuous fiber monofilaments / single tapes, and metal monofilaments / single tapes, and the metal monofilaments / single tapes and the continuous fiber monofilaments / single tapes are connected together by knotting;

[0051] S102. Before the metal on the surface of the monofilament or monobelt solidifies, metallurgically connecting the monofilament or monobelt with the rotating preform using rollers to produce a rotating preform comprising a metal inner cylinder / inner ring + a continuous fiber reinforced metal matrix composite material + a metal outer cylinder / outer ring;

[0052] S103, performing hot isostatic pressing on the rotating body preform to achieve densification;

[0053] S104, performing CNC machining on the densified body of revolution preform to prepare a body of revolution structural part.

[0054] In the above embodiment, the inner cylinder, the wire / strip and the outer cylinder are formed by continuous one-time induction heating, thereby achieving the completion of the preparation of the rotating body structure in the same set of processing equipment.

[0055] In step 101, an induction heating method is used to apply a coating on the surface of a metal wire, a continuous fiber monofilament or a single tape, wherein the metal wire can be a titanium alloy, an aluminum alloy and an aluminum-lithium alloy, a magnesium alloy and a magnesium-lithium alloy, or a tungsten alloy; the continuous fiber can be a coarse SiC fiber (with a diameter of about 100 μm), a coarse Al2O3 fiber, a coarse B fiber, a bundled SiC fiber, a bundled C fiber, a knotted continuous carbon nanotube fiber, etc.; the coating can be the metal material mentioned above, can be an epoxy resin, a bismaleimide resin, a powder slurry of materials such as SiC, Al2O3, B, C, etc., or a reaction slurry that reacts to form ceramics, to prepare a metal monofilament or single tape whose core and coating are the same or different materials, a continuous fiber-reinforced metal-based composite monofilament or single tape, a continuous carbon fiber-reinforced resin-based composite monofilament or single tape, and a continuous carbon fiber-reinforced ceramic-based composite monofilament or single tape.

[0056] By adopting the induction heating method and basically the same process path, in the same equipment, composite metal monofilaments or single tapes, continuous fiber reinforced metal matrix composite material monofilaments or single tapes, continuous fiber reinforced resin matrix composite material monofilaments or single tapes, and continuous fiber reinforced ceramic matrix composite material monofilaments or single tapes can be prepared. They can be used to manufacture a variety of metal structural parts, continuous fiber reinforced metal matrix composite material structural parts, continuous fiber reinforced resin matrix composite material structural parts, and continuous fiber reinforced ceramic matrix composite material structural parts, and have the characteristics of low manufacturing cost, high efficiency and excellent performance.

[0057] In step 102, a preform of a metal inner cylinder (or inner ring) + a continuous fiber reinforced metal matrix composite material + a metal outer cylinder (or outer ring) is prepared by continuously coating the surface of the metal and the continuous fiber monofilament or single tape and then rolling them immediately.

[0058] If the metal and continuous fiber reinforced metal matrix composite material is used, the metal and continuous fiber reinforced metal matrix composite material single filament or single tape can be wound onto a metal inner cylinder or metal inner ring, and then covered with a metal outer cylinder or metal outer ring. The assembled preform is then edge-sealed and vacuum-baked. The edge-sealing welding can be a fusion welding method such as electron beam welding or argon arc welding. When the welding method is electron beam welding or argon arc welding, the contact annular surface between the metal inner cylinder or metal inner ring and the metal outer cylinder or metal outer ring is parallel to the axis. The vacuum-encapsulated preform is then hot isostatically pressed to achieve diffusion bonding between the metal and continuous fiber reinforced metal matrix composite material single filament or single tape, between the metal and continuous fiber reinforced metal matrix composite material single filament or single tape and the metal inner cylinder or metal inner ring, between the metal outer cylinder or metal outer ring, and between the metal inner cylinder or metal inner ring and the metal outer cylinder or metal outer ring. The excess metal material is then removed by CNC machining to produce rotating structural parts such as ribbed cylinders, hollow shafts, and blade rings. The metal inner cylinder, the metal wire material, and the coating material can be made of different materials or the same material.

[0059] If it is one of metal, continuous fiber reinforced metal matrix composite material, and continuous fiber reinforced resin matrix composite material, the single wire or single tape of the metal, continuous fiber reinforced metal matrix composite material, and continuous fiber reinforced resin matrix composite material can be wound onto the metal inner cylinder or the metal inner ring, and the metal outer cylinder or the metal outer ring is covered on the outside, and then the assembled preform is edge-sealed and vacuum-baked, wherein the edge-sealing welding can be a fusion welding method such as electron beam welding and argon arc welding, or a solid-state welding method such as inertia friction welding. When the welding method is electron beam welding or argon arc welding, the contact annular surface of the metal inner cylinder or the metal inner ring and the metal outer cylinder or the metal outer ring is parallel to the axis. When the welding method is inertia friction welding, the contact annular surface of the metal inner cylinder or the metal inner ring and the metal outer cylinder or the metal outer ring is at a certain angle to the axis. An air inlet is left at one end of the welded preform and an air outlet is left at the other end. Then, a pressure casting method is used to preheat the welded preform to a set temperature in a vacuum environment. Molten metal or resin is injected into the air inlet to fill the pores inside the preform, thereby achieving connection between metal and continuous fiber reinforced metal matrix composite monofilaments or monobelts, or between continuous fiber reinforced resin matrix composite monofilaments or monobelts, and between metal and continuous fiber reinforced metal matrix composite monofilaments or monobelts, or between continuous fiber reinforced resin matrix composite monofilaments or monobelts and metal inner cylinder or metal inner ring, metal outer cylinder or metal outer ring, and between metal inner cylinder or metal inner ring and metal outer cylinder or metal outer ring. Then, CNC machining is used to remove excess metal material to process metal and continuous fiber reinforced metal matrix composite, continuous fiber reinforced resin matrix composite ribbed cylinder, hollow shaft, blade ring and other rotating structural parts. The metal inner cylinder, metal wire material, and coating material here can be different materials or the same material.

[0060] If it is a tungsten wire or continuous fiber reinforced ceramic matrix composite material, the single wire or single tape of the tungsten wire or continuous fiber reinforced ceramic matrix composite material can be wound onto a ceramic inner cylinder or a ceramic inner ring, and a ceramic outer cylinder or a ceramic outer ring is put on the outside. An air inlet hole is left at one end of the combined preform and an exhaust hole is left at the other end. The preform is preheated to a certain temperature, and then a pressure casting method is used. Under an argon protection environment, ceramic slurry is injected into the air inlet to fill the pores inside the preform. The preform is then directly placed in a high vacuum pressureless sintering furnace for sintering to achieve sintering connections between the single wires or single tapes of the tungsten wire or continuous fiber reinforced ceramic matrix composite material, as well as between the single wires or single tapes of the tungsten wire or continuous fiber reinforced ceramic matrix composite material and the ceramic inner cylinder or ceramic inner ring, the ceramic outer cylinder or ceramic outer ring, and the ceramic inner cylinder or ceramic inner ring and the ceramic outer cylinder or ceramic outer ring. Then, CNC machining is used to remove excess ceramic material to process rotating structural parts such as ribbed cylinders, hollow shafts, and blade rings made of tungsten wire or continuous fiber reinforced ceramic matrix composite materials.

[0061] The two steps of passing the metal monofilament or monotape, continuous fiber reinforced metal matrix composite monofilament or monotape, continuous fiber reinforced resin matrix composite monofilament or monotape, and continuous fiber reinforced ceramic matrix composite monofilament or monotape through the induction heating crucible and winding it on the inner cylinder (or inner ring) are combined in one device. The forming environment is a vacuum environment, which not only improves the efficiency but also ensures the forming quality.

[0062] As an optional embodiment, the metal and continuous fiber pass through the crucible at a speed of 0.5 m / s to 2.0 m / s. To prevent the metal and continuous fiber monofilaments or ribbons from melting or causing violent interfacial reactions between the continuous fiber and the molten metal as they pass through the crucible, the speed of the monofilaments or ribbons passing through the crucible is within a range of 0.5 m / s to 2.0 m / s.

[0063] As an optional embodiment, the monofilament / single tape is rolled into a regular square or rectangle.

[0064] Specifically, after the monofilament or monofilament passing through the crucible is rolled, the interface shape is changed from a circular or irregular long strip to a square or rectangular. During winding, the monofilament or monotape can be densely packed, and the gaps left are very small. Whether it is subsequent hot isostatic pressing, pressure casting, or vacuum pressureless sintering, it can be ensured that the formed parts have good density. Especially for the hot isostatic pressing process, if it is a circular cross-section, there is about 10% volume shrinkage, which can easily lead to fiber breakage. However, when using a square cross-section monofilament or a rectangular interface monotape, the shrinkage is greatly reduced, avoiding the fiber from breaking during the hot isostatic pressing process, solving a very critical technical problem of continuous fiber reinforced metal matrix composite materials, such as blade ring structural parts. Moreover, during the shaping process, the material is still in liquid state, and immediately turns into solid state after shaping. Shaping is carried out under liquid conditions, with low deformation resistance and little damage to the fiber.

[0065] In order to ensure that the copper alloy and titanium alloy are fully immersed in the gaps of the fibers, the single wire or single strip just out of the molten pool is rolled. On the one hand, the single wire or single strip can be densified; on the other hand, the single wire or single strip can be rolled into a regular square or rectangle, which is conducive to the subsequent dense arrangement of the single wire or single strip. In addition, during the subsequent hot isostatic pressing, the shrinkage of the square or rectangular interface is also smaller, which is more conducive to obtaining high-precision and high-performance integral blade ring structural parts. Mainly, after the shrinkage rate is reduced, the shrinkage of the structural parts along the axial and circumferential directions is reduced, thereby avoiding the fiber from being subjected to excessive stress and causing breakage.

[0066] The rolling of single wire or single tape is carried out by using rollers. The rollers have a structure with large diameters at both ends and small diameters in the middle. A pair of rollers can roll out single wire / single tape with a square or rectangular interface.

[0067] As an optional embodiment, the single tape is a single tape with unidirectionally arranged fibers or a single tape with continuous carbon fibers woven two-dimensionally; wherein the acute angle between the fiber arrangement direction and the direction of the single tape is ≤10°.

[0068] Figure 2 is a schematic flow chart of a method for preparing a rotating body structure provided by an embodiment of the present invention, such as Figure 2 As shown, the method may include the following steps:

[0069] S201, processing the inner cylinder / inner ring and the outer cylinder / outer ring, and pickling the surfaces;

[0070] S202, applying a coating on the surface of the wire / strip by induction heating;

[0071] S203, winding the wire material / strip material on the outer surface of the inner cylinder / inner ring, and sleeve the outer cylinder / outer ring on the outer surface of the wound inner cylinder / inner ring to form a first preform;

[0072] S204, performing edge sealing welding, vacuum baking, and vacuum packaging on the first preform in sequence to form a second preform;

[0073] S205, performing hot isostatic pressing on the second preform to achieve diffusion bonding;

[0074] S206 , performing CNC machining on the second preform after diffusion bonding to prepare a rotating body structure.

[0075] In the above embodiment, a CNC machining method is used to pre-machine the metal inner cylinder and the metal outer cylinder, and then the wire / strip is wound on the outer wall of the metal inner cylinder, and then the metal outer cylinder is sleeved after winding.

[0076] In step S201, the inner cylinder or inner ring, the outer cylinder or outer ring are CNC machined, and the surface is pickled to remove surface dirt and oxide scale. The outer cylinder or outer ring, the inner cylinder or inner ring can be made of metal materials such as titanium alloy, aluminum alloy and aluminum-lithium alloy, magnesium alloy and magnesium-lithium alloy, copper alloy, tungsten alloy, steel, etc., or can be made of ceramic materials.

[0077] In step S202, an induction heating method is used to apply a coating on the surface of a metal wire or strip, a continuous fiber monofilament or a single tape, wherein the metal wire can be a titanium alloy, an aluminum alloy and an aluminum-lithium alloy, a magnesium alloy and a magnesium-lithium alloy, or a tungsten alloy; the continuous fiber can be a coarse SiC fiber (with a diameter of about 100 μm), a coarse Al2O3 fiber, a coarse B fiber, a bundled SiC fiber, a bundled C fiber, a knotted continuous carbon nanotube fiber, etc.; the coating can be the metal material mentioned above, can be an epoxy resin, a bismaleimide resin, a powder slurry of materials such as SiC, Al2O3, B, C, or a reaction slurry that reacts to form ceramics, to prepare a metal monofilament or a single tape whose core and coating are the same or different materials, a continuous fiber-reinforced metal-based composite monofilament or a single tape, a continuous carbon fiber-reinforced resin-based composite monofilament or a single tape, and a continuous carbon fiber-reinforced ceramic-based composite monofilament or a single tape.

[0078] By adopting the induction heating method and basically the same process path, in the same equipment, composite metal monofilaments or single tapes, continuous fiber reinforced metal matrix composite material monofilaments or single tapes, continuous fiber reinforced resin matrix composite material monofilaments or single tapes, and continuous fiber reinforced ceramic matrix composite material monofilaments or single tapes can be prepared. They can be used to manufacture a variety of metal structural parts, continuous fiber reinforced metal matrix composite material structural parts, continuous fiber reinforced resin matrix composite material structural parts, and continuous fiber reinforced ceramic matrix composite material structural parts, and have the characteristics of low manufacturing cost, high efficiency and excellent performance.

[0079] If the material is metal or continuous fiber reinforced metal matrix composite material, the metal or continuous fiber reinforced metal matrix composite material single filament or single tape can be wound onto a metal inner cylinder or metal inner ring, and then a metal outer cylinder or metal outer ring is put on the outside. The assembled preform is then edge-sealed and vacuum-baked. The edge-sealing welding can be a fusion welding method such as electron beam welding or argon arc welding. When the welding method is electron beam welding or argon arc welding, the contact annular surface between the metal inner cylinder or metal inner ring and the metal outer cylinder or metal outer ring is parallel to the axis. The vacuum-encapsulated preform is then hot isostatically pressed to achieve diffusion bonding between the metal or continuous fiber reinforced metal matrix composite material single filament or single tape, between the metal or continuous fiber reinforced metal matrix composite material single filament or single tape and the metal inner cylinder or metal inner ring, between the metal outer cylinder or metal outer ring, and between the metal inner cylinder or metal inner ring and the metal outer cylinder or metal outer ring. The excess metal material is then removed by CNC machining to produce rotating structural parts such as ribbed cylinders, hollow shafts, and blade rings. The metal inner cylinder, the metal wire material, and the coating material can be made of different materials or the same material.

[0080] If it is one of metal, continuous fiber reinforced metal matrix composite material, and continuous fiber reinforced resin matrix composite material, the single wire or single tape of the metal, continuous fiber reinforced metal matrix composite material, and continuous fiber reinforced resin matrix composite material can be wound onto the metal inner cylinder or the metal inner ring, and the metal outer cylinder or the metal outer ring is covered on the outside, and then the assembled preform is edge-sealed and vacuum-baked, wherein the edge-sealing welding can be a fusion welding method such as electron beam welding and argon arc welding, or a solid-state welding method such as inertia friction welding. When the welding method is electron beam welding or argon arc welding, the contact annular surface of the metal inner cylinder or the metal inner ring and the metal outer cylinder or the metal outer ring is parallel to the axis. When the welding method is inertia friction welding, the contact annular surface of the metal inner cylinder or the metal inner ring and the metal outer cylinder or the metal outer ring is at a certain angle to the axis. An air inlet is left at one end of the welded preform and an air outlet is left at the other end. Then, a pressure casting method is used to preheat the welded preform to a set temperature in a vacuum environment. Molten metal or resin is injected into the air inlet to fill the pores inside the preform, thereby achieving connection between metal and continuous fiber reinforced metal matrix composite monofilaments or monobelts, or between continuous fiber reinforced resin matrix composite monofilaments or monobelts, and between metal and continuous fiber reinforced metal matrix composite monofilaments or monobelts, or between continuous fiber reinforced resin matrix composite monofilaments or monobelts and metal inner cylinder or metal inner ring, metal outer cylinder or metal outer ring, and between metal inner cylinder or metal inner ring and metal outer cylinder or metal outer ring. Then, CNC machining is used to remove excess metal material to process metal and continuous fiber reinforced metal matrix composite, continuous fiber reinforced resin matrix composite ribbed cylinder, hollow shaft, blade ring and other rotating structural parts. The metal inner cylinder, metal wire material, and coating material here can be different materials or the same material.

[0081] If it is a tungsten wire or continuous fiber reinforced ceramic matrix composite material, the single wire or single tape of the tungsten wire or continuous fiber reinforced ceramic matrix composite material can be wound onto a ceramic inner cylinder or a ceramic inner ring, and a ceramic outer cylinder or a ceramic outer ring is put on the outside. An air inlet hole is left at one end of the combined preform and an exhaust hole is left at the other end. The preform is preheated to a certain temperature, and then a pressure casting method is used. Under an argon protection environment, ceramic slurry is injected into the air inlet to fill the pores inside the preform. The preform is then directly placed in a high vacuum pressureless sintering furnace for sintering to achieve sintering connections between the single wires or single tapes of the tungsten wire or continuous fiber reinforced ceramic matrix composite material, as well as between the single wires or single tapes of the tungsten wire or continuous fiber reinforced ceramic matrix composite material and the ceramic inner cylinder or ceramic inner ring, the ceramic outer cylinder or ceramic outer ring, and the ceramic inner cylinder or ceramic inner ring and the ceramic outer cylinder or ceramic outer ring. Then, CNC machining is used to remove excess ceramic material to process rotating structural parts such as ribbed cylinders, hollow shafts, and blade rings made of tungsten wire or continuous fiber reinforced ceramic matrix composite materials.

[0082] The two steps of passing the metal monofilament or monotape, continuous fiber reinforced metal matrix composite monofilament or monotape, continuous fiber reinforced resin matrix composite monofilament or monotape, and continuous fiber reinforced ceramic matrix composite monofilament or monotape through the induction heating crucible and winding it on the inner cylinder (or inner ring) are combined in one device. The forming environment is a vacuum environment, which not only improves the efficiency but also ensures the forming quality.

[0083] In step S205, the preform after vacuum packaging is hot isostatically pressed to achieve diffusion connection between the metal and continuous fiber reinforced metal matrix composite material monofilaments or single tapes, as well as between the metal and continuous fiber reinforced metal matrix composite material monofilaments or single tapes and the inner cylinder or inner ring, the outer cylinder or outer ring, and the inner cylinder or inner ring and the outer cylinder or outer ring.

[0084] This method can produce a variety of complex rotating structural components, including belt-and-ribbon structures, where the ribs are made of sheet metal and the skin is constructed from a two-dimensional woven or wire-woven fabric. These rotating structural components can include cylinders, hollow shafts, and blade rings, offering high performance, low manufacturing costs, and high efficiency.

[0085] As an optional embodiment, the wire / strip is a composite titanium alloy monofilament or monotape, or a continuous SiC fiber reinforced titanium alloy composite monofilament or monotape, or a continuous carbon fiber reinforced copper-based composite monofilament or monotape.

[0086] As an optional embodiment, the surface of the wire / strip is coated with a layer of titanium alloy or copper alloy.

[0087] Specifically, a layer of titanium alloy, copper alloy, aluminum alloy, aluminum-lithium alloy, magnesium alloy, and magnesium-lithium alloy material is coated on the surface of a single wire or a single tape. In order to prevent the impurity elements in the copper alloy from reacting in situ with the titanium to produce brittle intermetallic compounds, resulting in a decrease in the performance of the titanium / copper interface, thereby causing a decrease in the performance of the titanium alloy / carbon fiber reinforced copper-based composite material, the copper alloy is preferably white copper, such as B19 copper alloy.

[0088] The coating can be any of metal, resin, ceramic slurry and other materials. For materials such as resin, ceramic slurry, etc., the induction heating method can also be used to heat the resin and ceramic slurry so that they are in a liquid state. When the metal and continuous fiber monofilaments or single tapes pass through the molten pool, the resin and ceramic slurry are coated on the surface of the metal and continuous fiber to prepare continuous monofilaments or single tapes of metal and continuous fiber reinforced resin-based composites or ceramic-based composites. However, the induction heating coil cannot heat directly. In order to achieve uniform and stable heating of the resin and ceramic slurry, a metal container is set inside the split melting crucible. The induction melting crucible induction heats it but does not melt it. The metal container then heats the resin and ceramic slurry inside to keep it in a molten state. This heating method heats more evenly. In order to facilitate the metal and continuous fiber monofilaments or single tapes to pass through from the bottom, openings or slots are set at the bottom of the metal container. When the continuous monofilaments or single tapes pass through the holes or slots at the bottom of the metal container, they are transformed into monofilaments or single tapes of metal and continuous fiber reinforced resin-based composite materials, or metal and continuous fiber reinforced ceramic-based composite materials.

[0089] As an optional embodiment, the filament / tape is a single tape with unidirectional fibers or a single tape formed by two-dimensionally weaving continuous carbon fibers; the acute angle between the fiber arrangement direction and the direction of the single tape is ≤10°. Specifically, this angle is designed to ensure that the main stress is borne in the circumferential direction while also bearing a portion of the load in the axial direction, thereby preventing axial creep deformation of the matrix under high temperature conditions, which may lead to component failure.

[0090] As an optional embodiment, the filament / tape is a high-performance composite carbon nanotube fiber obtained by continuously knotting a single or multiple carbon nanotubes and then stretching and pre-tightening them.

[0091] Among them, carbon nanotubes have very good compression and tension properties. When a carbon nanotube fiber is knotted by itself, or multiple carbon nanotube fibers are knotted with each other, the continuous knots should be close together, and one knot should fall on the previous knot to achieve continuous and tight knotting. In this way, the carbon nanotubes are compressed under their own tensile stress. The more compressed, the denser the carbon nanotube fibers are, making the knotted carbon nanotube fibers have very high mechanical properties. The knotting form can be various knotting methods to achieve the compression of the carbon nanotube fibers themselves. By using a single or multiple carbon nanotube fibers to knot themselves or to knot each other, high-performance fibers are obtained, which are further used in the preparation of high-performance cylindrical parts, hollow shafts or annular parts.

[0092] Of course, this method can also be applied to other metal materials, such as aluminum alloy, magnesium alloy and the like.

[0093] As an optional embodiment, in step S202, coating the surface of the wire material with a coating by induction heating is performed, specifically comprising:

[0094] When the coating is a metal material, a split-type induction suspension melting method is used for direct melting, a layer of the coating is applied to the surface of the wire / strip, and the wire / strip coated with the coating is rolled;

[0095] When the coating is a non-metallic material, a split-type induction suspension melting is used to indirectly heat the metal container, the metal container heats the non-metallic material and keeps it in a molten state, a layer of the coating is applied to the surface of the wire / strip, and the wire / strip coated with the coating is rolled.

[0096] Specifically, composite metal (titanium alloy, copper alloy, aluminum alloy, magnesium alloy) monofilament or monotape, continuous SiC fiber reinforced titanium alloy composite monofilament or monotape, continuous carbon fiber reinforced copper matrix composite monofilament or monotape are all produced by split-petal induction suspension melting method, such as Figure 3 As shown, a layer of titanium alloy, copper alloy, aluminum alloy, or magnesium alloy is coated on the surface of the single wire or single ribbon. To prevent the induction coil 3 from overheating the metal wire or fiber passing through the bottom hole, the lowermost end of the induction coil 3 cannot be lower than the lowest point in the inner cavity of the melting crucible 2.

[0097] In order to improve the forming efficiency and reduce the subsequent processing steps, the preparation and winding or laying of metal and metal matrix composite monofilaments or monotapes are combined. Figure 4 The technical solution adopts the method of suspension smelting to melt the metal, and then uses a metal or continuous fiber single wire or single belt to pass through the suspended smelting crucible 2 and pass through the bottom hole. When the metal on the surface of the single wire or single belt has not solidified, the single wire or single belt is connected to the rotating metal inner cylinder 7 (inner ring) preform below by a roller 6. A metallurgical connection has been formed between the single wire or single belt. Then the inner cylinder (inner ring) preform is removed and covered with a metal cylinder (or outer ring) and a metal hollow outer cylinder. After baking and vacuum packaging, it is directly hot isostatically pressed and then processed by CNC to manufacture a rotating structural part. Figure 4 As shown, when a single wire or a single tape is wound on the metal inner cylinder 7 (metal inner ring), the metal inner cylinder 7 (metal inner ring) can rotate along the rotation axis and move along the axis, and the inductively suspended melting crucible 2 can move along the x, y, and z directions, so that the single wire or single tape can be wound and connected on the surface of the metal inner cylinder 7 (metal inner ring).

[0098] By adopting a method, the preparation of rotating body structural parts of single metal, composite metal, continuous fiber reinforced metal matrix composite material, and metal / continuous fiber reinforced resin matrix composite material is realized in the same equipment. It has good applicability and can be used to manufacture rotating body structural parts of various structural forms.

[0099] The rollers play the following roles:

[0100] (1) Improve the wettability of liquid metal and continuous fiber, eliminate the gaps in the fiber gaps that are not completely filled with liquid metal, and densify the single wire or single tape;

[0101] (2) It plays a guiding and pressing role, making it easier to press the single wire or single tape down to contact the preform, and to lay the wire or tape according to the trajectory;

[0102] (3) The single wire or single strip coated with liquid metal is connected to the preform under the action of rolling force.

[0103] For single alloy wire or strip, composite alloy wire or strip, winding can be performed by rolling, or the connection between the single wire or strip and the preform can be achieved by stirring. During stirring, the main shaft rotates, and during rolling, the main shaft does not rotate. The stirring processing head can be replaced with a roller, and switching between the two processing modes is also relatively convenient. This technical solution further integrates the two processes of preparing single wire or strip and winding the single wire or strip on the rotating inner cylinder preform into a single device. The entire forming system is placed in a vacuum chamber, which not only improves preparation efficiency but also ensures forming quality, and has great technical advantages.

[0104] For some low-melting-point alloys or resin materials, continuous fibers (C fibers, SiC fibers, B fibers, etc.) can be wound onto a metal inner cylinder (inner ring) at different angles, and then covered with a metal outer cylinder (outer ring). The contact annular surfaces of the metal inner cylinder (inner ring) and the metal outer cylinder (outer ring) are at a certain angle to the axis. Inertia friction welding or electron beam welding can be used to weld the metal inner cylinder (inner ring) and the metal outer cylinder (outer ring) wound with continuous fibers together. Air inlet holes and exhaust holes are respectively set on the sides of the welded metal inner cylinder (inner ring) and the metal outer cylinder (outer ring), and the welded preform is heated to a certain temperature, generally above the melting point of the copper alloy and resin. The molten copper alloy and resin are injected into the fiber preform between the metal inner cylinder (inner ring) and the metal outer cylinder (outer ring) through the air inlet holes by the pressure casting method. The gas between the gaps between the fiber preforms is discharged from the exhaust holes until the copper alloy and the resin completely fill the gaps inside the fiber preforms, as well as the gaps between the fiber preforms and the metal inner cylinder (inner ring) and the metal outer cylinder (outer ring). In this way, a rotating body structure of metal / continuous fiber reinforced copper-based composite materials and metal / continuous fiber reinforced resin-based composite materials is prepared. The materials of the metal inner cylinder and the metal outer cylinder can be titanium alloy, aluminum alloy, aluminum-lithium alloy, magnesium alloy, magnesium-lithium alloy, high-strength steel and the like.

[0105] Induction heating is used to coat the metal and continuous fiber surfaces with metal materials, resins, and ceramic slurries to obtain continuous monofilaments or single tapes, which are then rolled layer by layer along a trajectory and connected to preforms. This is not only applicable to the manufacture of rotating structural parts, but also to the manufacture of other structural parts with complex profiles, such as panels, skins, frame beams, and other structural parts. Similarly, the continuous fibers are wound layer by layer along a trajectory, and then the metal inner cylinder and the metal outer cylinder are welded together. Resin or molten copper alloy is injected into the wound continuous fibers between the metal inner cylinder and the metal outer cylinder. This is not only applicable to the manufacture of rotating structural parts, but also to the manufacture of other structural parts with complex profiles.

[0106] As an optional embodiment, the wire / strip is rolled into a regular square or rectangle.

[0107] Specifically, after the monofilament or monofilament passing through the crucible is rolled, the interface shape is changed from a circular or irregular long strip to a square or rectangular. During winding, the monofilament or monotape can be densely packed, and the gaps left are very small. Whether it is subsequent hot isostatic pressing, pressure casting, or vacuum pressureless sintering, it can be ensured that the formed parts have good density. Especially for the hot isostatic pressing process, if it is a circular cross-section, there is about 10% volume shrinkage, which can easily lead to fiber breakage. However, when using a square cross-section monofilament or a rectangular interface monotape, the shrinkage is greatly reduced, avoiding the fiber from breaking during the hot isostatic pressing process, solving a very critical technical problem of continuous fiber reinforced metal matrix composite materials, such as blade ring structural parts. Moreover, during the shaping process, the material is still in liquid state, and immediately turns into solid state after shaping. Shaping is carried out under liquid conditions, with low deformation resistance and little damage to the fiber.

[0108] In order to ensure that the copper alloy and titanium alloy are fully immersed in the gaps of the fibers, the single wire or single strip just out of the molten pool is rolled. On the one hand, the single wire or single strip can be densified; on the other hand, the single wire or single strip can be rolled into a regular square or rectangle, which is conducive to the subsequent dense arrangement of the single wire or single strip. In addition, during the subsequent hot isostatic pressing, the shrinkage of the square or rectangular interface is also smaller, which is more conducive to obtaining high-precision and high-performance integral blade ring structural parts. Mainly, after the shrinkage rate is reduced, the shrinkage of the structural parts along the axial and circumferential directions is reduced, avoiding the fiber from being subjected to excessive stress and causing breakage.

[0109] The rolling of the monofilament / single tape is carried out by using rollers, which have a large diameter at both ends and a small diameter in the middle. A pair of rollers can roll out a monofilament / single tape with a square or rectangular interface.

[0110] As an optional embodiment, the titanium alloy circular ring plate is processed by numerical control machining and cutting, wherein the cutting method can specifically be high-pressure water cutting or laser cutting.

[0111] As an optional embodiment, the first preform is subjected to vacuum baking, specifically comprising the following steps: leaving an air inlet hole at one end of the welded first preform and an air exhaust hole at the other end;

[0112] A pressure casting method is adopted to preheat the welded first preform to a set temperature in a vacuum environment, and molten filler is injected into the air inlet to fill the pores inside the first preform.

[0113] Specifically, when preparing continuous fiber reinforced metal matrix composite materials and continuous fiber reinforced resin matrix composite materials, a pressure casting method is adopted to inject low melting point metal and resin into the metal inner cylinder or inner ring and the internal space formed by the metal outer cylinder or outer ring. On the one hand, liquid metal or resin is used to fill the pores in the internal space. On the other hand, after the metal or resin solidifies, it solidifies together with the metal or resin in the wound monofilament or single belt and connects them together. Compared with the traditional pressure casting method, when performing pressure casting filling, a metal or resin coating already exists, and the filling metal Or resin, compared with filling metal or resin into the fiber preform, it is not easy to cause deformation and damage to the fiber preform. In order to maintain a certain shape, the traditional fiber preform also needs a temporary adhesive in the preform for shaping, and finally the temporary adhesive needs to be removed, but most temporary adhesives are difficult to completely remove. In the present application, metal or resin coating is used for fixing and shaping to ensure that adjacent fibers do not contact each other. After filling, it has better fiber uniformity, less fiber damage, and smaller overall deformation of the fiber preform, therefore, it has better performance.
