[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0034] The chemical powder is sprayed on the surface of the fiber fabric, and then heated to solidify it. The mechanical properties of the powdered fiber fabric after shaping are greatly improved compared with the fiber fabric. Mechanical properties mainly refer to the macroscopic properties of the material, such as elasticity, plasticity, hardness, impact resistance, etc. They are the main basis for selecting materials when designing various engineering structures. Various parameters that characterize the mechanical properties of the material are related to a series of internal and external factors such as the chemical composition of the material, external force characteristics (static, dynamic, impact, etc.), temperature, processing methods, etc. The chemical powder is, for example, epoxy resin powder, polyurethane powder, etc., and the fiber fabric is, for example, carbon fiber fabric, glass fiber fabric, composite fiber fabric, etc.

[0035] In order to shape the powdered fiber fabric into a specific shape and facilitate testing of its shaping performance, an embodiment of the present application provides a powdered fiber fabric shaping device, which includes an insulation layer, a heating layer and a cover layer arranged from the inside to the outside, and the outer surface of the cover layer is made into a preset shape, and the inner surface of the cover layer is adapted to the shape of the heating layer. With this design, the heating layer heats the cover layer, and the powdered fiber fabric is laid on the cover layer to complete heating and curing.

[0036] The powdering fiber fabric shaping device provided in the present application is described in detail below in conjunction with the accompanying drawings.

[0037] like Figures 1 to 3 The y-axis direction shown in is the first direction, and the x-axis direction is the second direction.

[0038] An exemplary embodiment of the present application provides a powdering fiber fabric shaping device, such as Figure 1 and Figure 2 As shown, the powdered fiber fabric shaping device includes a thermal insulation layer 100, a heating layer 200 and a cover layer from the inside to the outside. The powdered fiber fabric to be shaped is laid on the outer surface of the cover layer. The outer surface of the cover layer has a specific shape, and the inner surface of the cover layer is adapted to the shape of the heating layer 200. The heating layer 200 is used to heat the cover layer; the thermal insulation layer 100 is filled in the accommodating space enclosed by the heating layer 200.

[0039] In the powdered fiber fabric shaping device provided in this embodiment, the insulation layer 100 insulates the heating layer 200 so that the heat of the heating layer 200 is transferred to the cover layer as much as possible. The powdered fiber fabric is laid on the outer surface of the cover layer, heated and shaped, and solidified into a shape similar to the outer surface of the cover layer. With such a design, the powdered fiber fabric can be shaped into a specific shape by changing the shape of the cover layer and the heating layer 200. The powdered fiber fabric in this shape is also convenient for subsequent testing of its shaping performance.

[0040] It should be noted that, in some embodiments, the thermal insulation layer 100 is filled in the accommodation space enclosed by the heating layer 200, adapted to the shape of the heating layer 200, and a layer of thermal insulation layer 100 is laid close to the heating layer 200; in other embodiments, the thermal insulation layer 100 fills the accommodation space enclosed by the heating layer 200, which not only improves the thermal insulation effect, but also can better support the heating layer 200, so that the heating layer 200 and the cover layer are more closely attached, thereby improving the heating effect and the curing efficiency.

[0041] In some embodiments, Figure 2 and Figure 3 As shown, the powder-sprinkling fiber fabric shaping device also includes a base plate 400 and two support plates 500. The cross-section of the support plate 500 is "L"-shaped. The two support plates 500 are relatively arranged on both sides of the base plate 400 along the x-axis direction. The two support plates 500 are respectively fixed to the base plate 400 by fasteners 510. The two support plates 500 limit the heating layer 200 and play a role in supporting the heating layer 200; the thermal insulation layer 100 is filled in the enclosed space enclosed by the base plate 400 and the heating layer 200, and also plays a supporting role for the heating layer 200.

[0042] In some embodiments, Figure 2 As shown, the cover layer is composed of a forming portion and two bending portions 320. The two bending portions 320 are respectively arranged on both sides of the forming portion along the x-axis direction for supporting the forming portion. The cross section of the support plate 500 is two oppositely arranged "L" shapes, and the cross section of the bending portion 320 is also "L" shaped. Each bending portion 320 is respectively arranged back to back with a support plate 500.

[0043] The setting of the bending portion 320 can not only support the shaping portion and provide a setting space for the support plate 500, but also avoid contact between the powdered fiber fabric and the table top or the ground of the laboratory bench when the powdered fiber fabric is laid on the cover layer, thereby avoiding foreign matter from sticking to the surface of the powdered fiber fabric and affecting product quality.

[0044] In some embodiments, reference Figure 1 and Figure 2The powdering fiber fabric shaping device extends along the first direction (i.e., the y-axis direction in the figure), that is, the shaping part, the bending part 320, the bottom plate 400, the supporting plate 500 and the heating plate all extend along the first direction. The shaping part includes a horizontal plate 311, a first inclined plate 312, a second inclined plate 313 and two end plates, all extending along the first direction.

[0045] The first inclined plate 312 and the second inclined plate 313 are located on both sides of the horizontal plate 311, and there is an angle between them and the horizontal plate 311 respectively. The two end plates are arranged at the two ends of the shaping portion along the first direction. The horizontal plate 311, the first inclined plate 312, the second inclined plate 313, the two end plates, the bending portion 320 and the bottom plate 400 together form a closed space. The heating layer 200, the insulation layer 100 and the two support plates 500 are all located in the closed space. The closed space is more conducive to the insulation of the shaping device.

[0046] In some embodiments, Figure 2 As shown, the angle between the first inclined plate 312 and the horizontal plate 311 is equal to the angle between the second inclined plate 313 and the horizontal plate 311, that is, the cross-section of the structure enclosed by the shaping portion and the bottom plate 400 is approximately an isosceles trapezoid, and the powdered fiber fabric is laid on the horizontal plate 311, the first inclined plate 312 and the second inclined plate 313. The powdered fiber fabric after shaping is an isosceles trapezoid that does not include the bottom edge.

[0047] When testing the setting performance of the powdered fiber fabric that has been set using the setting device, it is only necessary to use a fixing device to fix one inclined surface of the powdered fiber fabric and let it hang in the air. For example, multiple clips are installed on the beam to clamp the edge of one inclined surface of the powdered fiber fabric. After the powdered fiber fabric is hung for a set period of time, the morphological changes of the powdered fiber fabric under the action of gravity are observed, and then the quality of its setting performance is determined.

[0048] In other embodiments, the cross-section of the structure enclosed by the shaping portion and the bottom plate 400 may also be in the shape of a triangle, a rectangle, a semicircle, etc., all within the scope of protection of the present application. By adjusting the shape of the shaping portion and matching the shape of the heating layer 200 with the shaping portion, the powdered fiber fabric can be shaped into a specific shape. For example, if the cross-section enclosed by the shaping portion and the bottom plate 400 is an isosceles triangle, that is, the length and width of the first inclined plate 312 and the second inclined plate 313 are equal and fit together, the powdered fiber fabric after shaping is in a bent shape.

[0049] In some embodiments, see Figure 1 and Figure 2The length range of the horizontal plate 311 in the first direction (i.e., the y-axis direction) is 1500±500mm, and the width in the second direction (i.e., the x-axis direction) is 25±3mm. The angle between the first inclined plate 312 and the horizontal plate 311 is 110°±10°, and the angle between the second inclined plate 313 and the horizontal plate 311 is 110°±10°. The length range of the first inclined plate 312 and the second inclined plate 313 in the first direction is 1500±500mm, and the width is 150±50mm.

[0050] In some embodiments, Figure 2 and Figure 3 As shown, the length of the bottom plate 400 in the second direction is 200±10 mm, the length of the bottom plate 400 in the first direction is 1500±500 mm, and the height of the bending portion 320 in the vertical direction is 20±3 mm.

[0051] In some embodiments, Figure 3 As shown, the powdered fiber fabric shaping device also includes a temperature control device 600, which is electrically connected to the heating layer 200. At least one wire outlet hole 410 is provided on the bottom plate 400, and the wire 610 for electrical connection passes through the wire outlet hole 410. The temperature control device 600 can control the temperature of the heating layer 200 to adapt to the curing temperature requirements of different powdered fiber fabrics.

[0052] In some embodiments, the heating layer 200 includes an electric heating wire and two layers of silicone. The electric heating wire is electrically connected to the wire 610 and will generate heat when powered on. The electric heating wire is laid between the two layers of silicone. The heat generated by the electric heating wire is conducted to the silicone layer, and then conducted to the cover layer by the silicone layer, thereby achieving the curing and shaping of the powdered fiber fabric.

[0053] Silicone has the advantages of high temperature resistance, high thermal conductivity, good insulation performance and softness. The heating layer 200 is designed in this way, which has fast heat generation, high thermal efficiency and is not easy to age. It can be made into various shapes as needed, and can better fit closely with cover layers of various shapes, which is beneficial to heat conduction and reduces heat loss.

[0054] In some embodiments, the material of the heating wire is nickel-chromium alloy, and the melting point of nickel-chromium alloy is between 1300°C and 1500°C. Therefore, it has good stability in high temperature environment, and has the advantages of high temperature resistance, corrosion resistance and wear resistance; the cover layer is made of stainless steel; the material of the insulation layer 100 is rock wool, and the rock wool product uses high-quality basalt, dolomite, etc. as the main raw materials. After being melted at a high temperature of more than 1450°C, it is centrifuged into fibers at high speed using an internationally advanced four-axis centrifuge. At the same time, a certain amount of adhesive, dust-proof oil, and water-repellent agent are sprayed in, and then collected by a cotton collector, through a pendulum method, and three-dimensional cotton laying, and then cured and cut to form different specifications; because rock wool is made of rock and contains a large number of tiny air layers inside, it has excellent thermal insulation performance, reduces the heat waste of the heating layer 200, and reduces power consumption.

[0055] It should be noted that, in other embodiments, the insulation layer 100, the heating layer 200 and the cover layer may also be made of other materials, and those skilled in the art may adjust them according to actual needs, which is not limited here.

[0056] The working process of the powdering fiber fabric shaping device provided in the present application is as follows:

[0057] Start the temperature control device 600. After reaching the set temperature, spread the powdered fiber fabric on the shaping part of the cover layer. The area of ​​the powdered fiber fabric cannot be larger than the total area of ​​the horizontal plate 311, the first inclined plate 312 and the second inclined plate 313. Heat and cure the powdered fiber fabric. After shaping into a shape similar to the shaping part, remove and clamp one of the inclined surfaces of the powdered fiber fabric. After hanging it for a set period of time, the shaping performance of the powdered fiber fabric can be determined by observing the morphological changes of the powdered fiber fabric.

[0058] The powdering fiber fabric shaping device provided by the present application realizes shaping of the powdering fiber fabric into a specific shape by arranging the insulation layer 100, the heating layer 200 and the cover layer from the inside to the outside, arranging the heating layer 200 and the cover layer in a close relationship and filling the insulation layer 100 in the accommodation space enclosed by the heating layer 200. The powdering fiber fabric shaped by the powdering fiber fabric shaping device provided by the present application is convenient to hang, thereby facilitating the testing of its mechanical properties, having a simple structure, convenient operation, and saving raw material costs.
