Abstract
Description
Technical Field
[0001] The present invention relates to a component and a method for producing such a component. Background Art
[0002] Although the invention can be used in many applications, the invention and its underlying problems will be explained in more detail in connection with passenger aircraft. However, the described method and apparatus can also be used in vehicles in all sectors of the transportation industry, for example in road vehicles, in rail vehicles, in general aircraft or in ships. Furthermore, the invention can be used in any type of two-dimensional or three-dimensional workpiece and in the manufacture of such workpieces.
[0003] Manufacturing metal parts, especially those with complex geometries, often requires extensive milling or manufacturing in high-temperature processes such as welding. For example, the milling process requires thick metal sheets, where all the metal that is not required in the final part must be removed by milling until the final shape of the part is achieved. This milling process generates a lot of metal waste and has high raw material costs. On the other hand, high-temperature processes such as welding are usually not allowed because the mechanical properties of the material and the final workpiece cannot be maintained during these processes.
[0004] Automated fiber placement and automated tape placement are low temperature joining processes for joining materials. Automated fiber placement and automated tape placement are known processes for composite material manufacturing and are also used in processes for manufacturing aircraft parts. Summary of the invention
[0005] In this context, the object of the present invention is to find a solution for manufacturing metal components which requires less material and maintains the mechanical properties of the final workpiece.
[0006] This object is achieved by a component having the features of one aspect and a method having the features of another aspect.
[0007] According to a first aspect of the present invention, there is provided a component comprising a first subcomponent and a second subcomponent, each subcomponent being at least partially composed of a metal or metal alloy material or having a surface or surface area that is at least partially metallized. The first subcomponent and the second subcomponent are provided with a pair of connection interfaces configured to establish a permanent connection of the first subcomponent and the second subcomponent, wherein at least one of the pair of connection interfaces comprises nanowires.
[0008] Nanowires are grown on the surface of one or both of the connection interfaces, which are then pressed together with the treated surface. In the process, nanowire interlocking, diffusion of metal atoms, and subcomponent bonding occur, thereby providing good connection mechanical properties. In particular, the establishment of a permanent connection can occur within a few milliseconds at standard room temperature. If only one of the connection interfaces of the subcomponents to be bonded is covered with nanowires, bonding may require higher temperatures, particularly up to 170°C, and longer times of up to 10 seconds. Both variations are included in the present invention.
[0009] Another aspect of the present invention is a method for providing a component, the component comprising at least a first subcomponent and a second subcomponent, each subcomponent consisting entirely or partially of a metal or metal alloy material or having a surface or surface area that is at least partially metallized, the first subcomponent and the second subcomponent being provided with a pair of connection interfaces configured to establish a permanent connection of the first subcomponent and the second subcomponent. The method comprises establishing a permanent connection between the subcomponents at a pair of connection interfaces of the first subcomponent and the second subcomponent, wherein at least one of the first subcomponent and the second subcomponent is at least partially composed of a metal or metal alloy material or is provided with a connection interface that is at least partially metallized, wherein at least one of the connection interfaces comprises nanowires.
[0010] Advantageous embodiments and further developments are apparent from the further dependent aspects of the invention and from the description with reference to the drawings.
[0011] According to another aspect of the invention, at least one of the first subcomponent and the second subcomponent is an at least semi-finished workpiece having a geometry that provides a connection interface in at least one surface plane. This provides advantages in manufacturing finished components that have complex geometries and can only be manufactured by standard milling or welding processes.
[0012] According to an embodiment of the component, the surface plane of at least one of the first subcomponent and the second subcomponent is flat or at least partially curved. This can provide advantages during the manufacture of complex three-dimensional parts with a combination of curved and flat subcomponents, which are necessary to provide a finished component.
[0013] According to another embodiment of the component, at least one of the first subcomponent and the second subcomponent consists of or comprises a flexible material, or is configured as a strip or a sheet. The advantage of this embodiment is that cylindrical or nearly cylindrical components or components with complex three-dimensional geometries can also be provided with less manufacturing effort than standard processes (such as milling or high-temperature welding) by talking about the advantages of the permanent connection established using nanowires. Another advantage is that the freedom of possible geometries of the finished component is increased. The present invention is not limited to components of two-dimensional configuration, but also includes complex three-dimensional configurations.
[0014] According to another embodiment of the component, the first subcomponent and the second subcomponent each comprise a plurality of connection interfaces, wherein the subcomponents are permanently connected via at least one connection interface of the first component and at least one connection interface of the second subcomponent. The advantage of this embodiment is that a plurality of connection interfaces are provided and all or only specific connection interfaces can be selected to grow nanowires thereon and use these nanowires to join the subcomponents.
[0015] According to another embodiment of the component, at least one of the subcomponents has a three-dimensional, in particular cylindrical or at least partially cylindrical or other geometric shape. This allows the flexible subcomponents to be joined to those subcomponents to cover the surface of the subcomponents, thereby taking advantage of the nanowire joining of the subcomponents.
[0016] In an embodiment, the permanent connection established has a tensile shear strength of at least between 40 MPa and 60 MPa, a peel force of at least up to 1.7 N / mm, and a strength of at most 5 -9 to 10 -8 An advantage of this embodiment is that a finished component may be provided having enhanced physical properties that can be established without the use of standard manufacturing processes such as milling or high temperature welding processes.
[0017] According to another embodiment of the component, the first subcomponent is configured as a semi-finished tube or tank structure, which is made of metal or metal alloy or is provided with a metal surface or metallized surface or multiple metal surface areas or metallized surface areas, and the second subcomponent is configured as a strip, which is made of metal or metal alloy or is provided with a metal surface or metallized surface or multiple metal surface areas or metallized surface areas, and wherein the second subcomponent is laid on the first subcomponent, in particular by winding or bundling, and the joining is achieved by nanowires grown on one or both subcomponents or on corresponding connection interfaces provided on one or both subcomponents. In this embodiment, it is considered advantageous that the semi-finished tube or tank structure made of non-metallic material (e.g. a composite material having only a metal or metallized surface or a metal or metallized surface area) can be laid with a layer of metal or metal alloy material to obtain a leakproof cover or leakproof surface and / or a metal shell covering the composite material.
[0018] According to another embodiment of the component, the component is configured as an aircraft component, in particular a lightweight structural part for an aircraft. In this embodiment, it is considered advantageous that the component according to the invention can replace or supplement aircraft components or structural parts of an aircraft that are usually manufactured using milling or welding processes. The component according to the invention is configured in particular as a lightweight component, such as a structural part for an aircraft, for example made of aluminum or other suitable metals or metal alloys.
[0019] Aircraft components or structural parts are usually machined from solid material, resulting in material losses of up to 95% in the milling process, or are usually manufactured in welding processes, which require great efforts to maintain the mechanical and structural properties of the material and the final workpiece and the weld. With the component of the invention, an advantageous reduction in material usage can be achieved and the mechanical and structural properties of the material and the final workpiece can be maintained. The component of the invention provides an aircraft part that has the same properties as parts manufactured with state-of-the-art processes, thereby meeting quality requirements and complying with relevant regulations for aircraft parts.
[0020] Therefore, in another aspect of the invention, an aircraft may comprise a component according to the invention.
[0021] According to another embodiment of the method, at least one of the first subcomponent and the second subcomponent comprises a plurality of connection interfaces. This allows the method of the invention to advantageously easily establish connections and can even be used to generate complex structures that cannot be manufactured by standard processes such as milling or high temperature welding.
[0022] According to another embodiment of the method, establishing the permanent connection includes applying at least one of pressure, heat and electric current to at least one of the pair of connection interfaces. The advantage of the method of the present invention is that by using nanowires, the pressure or temperature required to establish the permanent connection is significantly lower than the pressure and temperature in the standard process, because the interlocking of the nanowires and the mutual diffusion of the metal atoms do not require elevated temperature and / or pressure or only need to be subjected to a short-term elevated temperature and / or pressure. This low temperature process maintains the material properties of the sub-components.
[0023] According to another embodiment, the method includes growing nanowires on at least one of the first subcomponent, the second subcomponent and the connection interface before establishing the permanent connection. This has the advantage that the nanowires only need to be grown on one of the subcomponents or the connection interface, and a permanent connection can still be established because the subcomponent or the connection interface provides a surface with which the nanowires can interlock.
[0024] According to another embodiment of the method, at least one of the first subcomponent and the second subcomponent consists of or comprises a flexible material, or is configured as a strip or sheet. This allows the method of the invention to be advantageously used for subcomponents with complex or curved surfaces.
[0025] According to another embodiment of the method, the metal or metal alloy material is selected from a group including titanium, magnesium, steel, copper, aluminum, Invar, alloys and mixtures of titanium, magnesium, steel, copper, aluminum, Invar, alloys. This allows the advantages of the present invention to be utilized by a pair of subcomponents consisting of the same or different materials. As encompassed in another embodiment of the present invention, the first subcomponent and / or the second subcomponent are particularly made of Invar to manufacture components with a low coefficient of thermal expansion. Such components are useful in, for example, low-temperature applications. In order to support the growth of nanowires on the Invar surface, these surfaces can be metallized, for example, with copper or another suitable metal material. In an alternative embodiment of the present invention, aluminum can be used as the metal material of the first subcomponent and / or the second subcomponent. If aluminum is used, a surface treatment can be applied to remove the oxide layer from the aluminum surface, thereby enabling the growth of nanowires or supporting the growth of nanowires.
[0026] In another embodiment of the invention, the method comprises depositing a layer of a metal or metal alloy material suitable for growing nanowires on at least one of the first subcomponent, the second subcomponent and the connecting interface. Non-limiting examples of suitable metal materials are copper, gold, silver and nickel. In the case where one or both subcomponents or the connecting interface do not consist of a metal or metal alloy material or do not consist entirely of a metal or metal alloy material and where the surface for growing the nanowires is provided by a metal or metal alloy layer deposited on such a material, such deposition also allows the method of the invention to be advantageously used.

[0033] The attached drawings are included to provide a further understanding of the present invention, and the attached drawings are incorporated into and constitute a part of this specification. The drawings illustrate embodiments of the present invention and are used together with the description to explain the principles of the present invention. Other embodiments of the present invention and many of the expected advantages of the present invention will be readily understood because they become better understood by reference to the detailed description. The elements in the drawings are not necessarily drawn to scale relative to each other. In the drawings, unless otherwise specified, similar reference numerals represent similar or functionally similar components.
[0034] Although specific embodiments are shown and described herein, it will be appreciated by those skilled in the art that various alternative and / or equivalent embodiments may be substituted for the specific embodiments shown and described without departing from the scope of the invention. Generally, this application is intended to cover any modifications or variations of the specific embodiments discussed herein.
[0035] In the drawings, unless otherwise specified, the same elements, features and components having the same function and the same effect are each given the same reference numeral.
[0036] Figure 1 A perspective view of a component 100 according to an embodiment of the present invention is schematically depicted. The component 100 includes a first subcomponent 101, which is configured as a curved plane, such as a sheet metal. A plurality of second subcomponents 102 having a linear extension relative to the first subcomponent 101 are permanently connected to the first subcomponent 101. The second subcomponent 102 is provided with a connection interface 110 in a surface of the sheet metal facing the first subcomponent 101. In the connection interface 110, nanowires have been grown for establishing a permanent connection between the first subcomponent 101 and the second subcomponent 102. During the manufacturing process of the component 100, the second subcomponent 102 is placed on a surface 120 of the first subcomponent 100, and pressure is applied to the connection interface 110 in a contact area 130 of the second subcomponent 102 in contact with the first subcomponent 101. The first subcomponent 101 is also provided with a connection interface 112 on which no nanowires are grown. In Figure 1 In the embodiment shown, only the second subcomponent 102 is provided with nanowires. Since the first subcomponent 101 is made of a thin sheet metal material, a permanent connection between the second subcomponent 102 and the first subcomponent 101 can be established by using nanowires grown only on the second subcomponent 102 and in the corresponding connection interface 110. When manufacturing the component 100 by the method according to the invention, welding is not required to establish a permanent connection between the first subcomponent 101 and the second subcomponent 102. This has the beneficial effect that the material properties of the subcomponents 101, 102 can be maintained compared to using a high temperature welding process.
[0037] like Figure 1As shown, the method according to the invention can be used to permanently connect subcomponents 101 , 102 having surfaces 120 , wherein it is foreseen that the connection interfaces 111 , 112 are curved or flat.
[0038] Figure 2 A perspective view of a component 100 according to another embodiment of the invention is schematically depicted. The component 100 consists of a first subcomponent 101 arranged as a metal plate 150 having a substantially flat or uniform surface 120. A total of four second subcomponents 102a, 102b, 102c, 102d are arranged on the first subcomponent 101, which form a rib 140 extending horizontally between a first edge 104 and a second edge 105 of the first subcomponent 101. Using the method according to the invention, the second subcomponents 102a, 102b, 102c, 102d intended to form the rib 140 on the first subcomponent 101 are permanently connected to the first subcomponent 101. The first subcomponent 101 and the second subcomponent 102 are provided with connection interfaces 111, 112 on which nanowires have been grown. The nanowires grow only in those areas of the first subcomponent 101 and the second subcomponent 102 that are dedicated to providing the connection interfaces 111, 112 between the subcomponents 101, 102. After the permanent connection between the first subcomponent 101 and the second subcomponent 102 has been established, the metal plate 150 as the first subcomponent 101 is provided with ribs 140 extending in an orthogonal direction relative to the main plane of the first subcomponent 101. In the milling process known in the art, a thick metal plate is required, wherein the ribs 140 are formed and obtained by milling excess metal material until the final thickness. This process can be completely replaced by the method of the present invention, thereby saving the material and work time required for milling.
[0039] Figure 2 The embodiment of the component shown can be used, for example, as an aircraft shell or other flat workpiece requiring increased rigidity. Figure 2 In addition to the method of component 100, Figure 2In an alternative embodiment not shown in the figure, the nanowires grown on the entire surface 120 of the first subcomponent 101 provide a non-specific connection interface 111. The second subcomponents 102a, 102b, 102c, 102d can be laid on this surface and permanently connected to the first subcomponent 101 by interlocking the nanowires with the connection interface 112. As an alternative, only those areas of the surface 120 of the second subcomponents 102a, 102b, 102c, 102d that are intended to be permanently connected to the first subcomponent 101 can be supplied with nanowires in the connection interfaces 111, 112 that are subsequently established. In this case as well, a permanent connection between the first subcomponent 101 and the second subcomponents 102a, 102b, 102c, 102d can be established by interlocking the nanowires. The present invention is not limited to the above alternatives and also includes embodiments in which nanowires are grown in the connection interfaces 111, 112 of the two subcomponents 101, 102a, 102b, 102c, 102d.
[0040] exist Figure 2 In the component 100 shown, the subcomponents 101, 102a, 102b, 102c, 102d are composed of a metallic material. Alternatively, the first subcomponent 101 and / or the second subcomponent 102a, 102b, 102c, 102d may be composed of a non-metallic material, for example, a composite material having a metallic layer deposited on the surface 120 or deposited on the surface 120 in the region intended to serve as a connecting interface 111, 112 to join the subcomponents 101, 102a, 102b, 102c, 102d. The second subcomponent 102a, 102b, 102c, 102d may also be formed by using a plurality of metal strips (not shown) stacked on top of each other to achieve the desired height of the ribs 140. The width of the ribs 140 is defined by the width of the strips and may be adapted to the requirements of the final geometry of the component. Each metal strip is provided with nanowires interconnected with the respective previous underlying metal strips.
[0041] Figure 3 A perspective view of a component 100 according to another embodiment of the present invention during manufacturing is schematically depicted. In this embodiment, the component 100 is configured as a tank having a cylindrical geometry. Such tanks are used in some cases to store liquid nitrogen (LN2) or liquid hydrogen (LH2), and particularly when used in the aircraft industry, such tanks can be composed of composite materials due to the requirement of weight reduction. The inventive method described herein is not limited to the first component 101 or the second component 102a, 102b, 102c, 102d composed of composite materials, but also includes other materials, such as steel. Advantageously, the outer surface 120 of such a tank is covered with a metal shell to reduce the leakage rate.
[0042] like Figure 3As shown, the first subcomponent 101 herein is a can body made of a composite material, and the second subcomponent 102 is constructed as a metal strip permanently connected to the first subcomponent using the method according to the present invention. In order to establish a permanent connection, the surface 120 of the first subcomponent 101 is surface treated to metallize the entire surface 120 or a specific area of the surface 120, thereby setting a connection interface 111 for bonding with a connection interface 112 of a strip-shaped second subcomponent 102 made of a metal material. In order to generate a metallized surface or a metallized surface area of the first subcomponent 101, a metal layer, such as a metal layer composed of copper, is deposited on the surface or a specific surface area where the connection interface 111, 112 will be formed. The deposition of the metal layer is performed by a standard process known in the art. The metal layer can be used as a basis for growing nanowires, which are used to establish a permanent connection between the strip-shaped second subcomponent 102 wound on the first subcomponent 101 by a winding tool 200. As an alternative to growing nanowires on the surface 120 of the first subcomponent 101, nanowires can be grown on a metal strip used as the second subcomponent 102. During the process of laying the metal tape on the tank surface 120, nanowire interlocking occurs. Interlocking can be supported by applying pressure and / or heat on the connection interface 111, 112. In order to increase the hydrogen tightness of the tank, the metal tape as the second subcomponent 102 is laid partially overlapping on the surface of the tank as the first subcomponent 101.
[0043] Figure 4 An embodiment of the method of the invention is schematically depicted. Figure 4The manufacturing process of a component 100 consisting of a first subcomponent 101 as a flat metal plate 150 provided with a connection interface 112 to which a second subcomponent 102 such as a strip or foil is permanently connected is depicted. The second subcomponent 102 consists of interlaced metal strips or foils which are themselves interconnected using nanowires in respective connection interfaces 111. Laying down a plurality of metal strips or foils as second subcomponents 102 will increase the thickness of the area of the metal plate 150 as the first subcomponent 101. A permanent connection of the first subcomponent 101 to the second subcomponent 102 is established using nanowires by nanowires grown on the bottom surface 160 of the lowest metal strip or foil. Each of the second subcomponents 102 is provided with a connection interface 111 having a nanowire coating 170. The nanowires are grown in those areas of the strips or foils intended to provide a connection interface 111 to the next strip or foil layer of the first subcomponent 101 or second subcomponent 102. During the laying process, the connection interface 111 is thus formed on the bottom surface 160, that is, the bottom surface is the side facing the top surface 180 of the lower layer of tape or sheet to which it is to be joined. In order to connect the metal tape or sheet and the first subcomponent 101 and the second subcomponent 102, a compaction roller 300 is provided, which applies pressure to the metal tape or sheet while moving on the subcomponents in the first direction R. The second subcomponent 102 is continuously fed into the compaction area so that it is laid on the previous layer and connected to it. The second subcomponent 102 is configured as a roll of flexible tape material on which nanowires are grown. Therefore, the endless metal tape can be modified with nanowires in a roll-to-roll process, so that the method is upgraded. In an alternative embodiment (not shown), the nanowires can be grown in the connection interfaces 111, 112 of both the first subcomponent 101 and the second subcomponent 102, or on the opposite surface of the second subcomponent 102. In order to avoid preliminary reactions of the nanowires, an intermediate protective layer is provided at least on the second subcomponent 102 , which is removed before the second subcomponent 102 is laid on the previously laid first subcomponent 101 with the nanowires grown in the connection interface 111 .
[0044] By means of the compaction roller 300 , pressure is applied to the connection interfaces 111 , 112 in which the nanowires are arranged, and bonding based on the interlocking of the nanowires is achieved.
[0045] Since the interlocking of the nanowires due to the diffusion of metal atoms in the nanowire surface region can be enhanced by applying temperature, the compaction roller 300 itself can be heated to introduce heat into the connection interface 111, 112. In another embodiment of the method of the present invention, the introduction of heat can be achieved by other means, such as by infrared radiation or wind heating (not shown) located next to the connection interface 111, 112 to establish a permanent connection. Due to the low temperature required to obtain the beneficial effects of the nanowire diffusion-based bonding process according to the method of the present invention, the mechanical properties of the subcomponents 101, 102 can be fully preserved compared to the high-temperature welding process used in the art.
[0046] Figure 5 Another embodiment of the method of the present invention is schematically depicted. Figure 5 In the embodiment of the present invention, the first subcomponent 101 is configured as a stack 301 of thin sheet or strip material layers, and the second subcomponent 102 is configured as a planar material having an area 302 protruding upward at an angle. Only the planar portion of the second subcomponent 102 will be connected to the first subcomponent 101. The connection interface 111 of the first subcomponent 101 is arranged in the planar portion of the first subcomponent 101. Instead of using a Figure 4 The compacting roller 300 shown, this embodiment of the method of the present invention uses a compactor 400, which applies pressure to the connection interface 111, 112 and realizes a permanent connection between the first subcomponent 101 and the second subcomponent 102 at the connection interface 111, 112. The compactor 400 applies pressure for a specific period of time and to the extent required to support the interlocking of the nanowires. In addition to pressure, the compactor 400 can also be a heating element that introduces heat into the connection interface 111, 112 to enhance the reactivity of the nanowires by increasing the diffusion of metal atoms at the surface area of the nanowires. As combined Figure 4 As mentioned above, Figure 5 In the embodiment of the method shown, one or more additional heat sources may be provided, such as infrared radiation or air heating, which directly influence the connection interfaces 111 , 112 during the production of the permanent connection between the subcomponents 101 , 102 .
[0047] In the foregoing detailed description, various features are combined together in one or more examples or embodiments for the purpose of simplifying the present disclosure. It should be understood that the above description is intended to be illustrative, rather than restrictive. It is intended to cover all alternatives, modifications and equivalents. After reading the above description, many other examples will be apparent to those skilled in the art. These embodiments are selected and described in order to best explain the principles of the present invention and its practical application, so that those skilled in the art can best utilize the present invention and various embodiments with various modifications suitable for the specific purposes envisioned.
