Composite forming method of multifunctional integrated composite material

Abstract

The invention relates to a compound forming method of a multifunctional integrated composite material. According to the different functional requirements of parts and components, partitions are carried out to obtain multiple functional areas and corresponding transition areas. According to the shape requirements of the functional areas, 3D printing or flexible guided three-dimensional The weaving forming process manufactures the transition area, obtains the transition area with adjacent functional area guide template information on both sides, respectively forms the Z-direction reinforcement array of the adjacent functional area on both sides of the transition area, and completes the weaving and forming of all functional areas , to obtain a multi-functional integrated composite material prefabricated body, and perform simultaneous impregnation and curing of a single matrix material or multiple matrix materials to realize the composite forming of a multi-functional integrated composite material. The composite forming method proposed by the present invention adopts different numbers and types of reinforcing bodies, base materials and suitable forming processes for synchronous weaving and forming for different functional areas. At the same time, the preformed transition area can isolate the two functional areas on both sides. It satisfies the simultaneous impregnation of various matrix materials, and on the basis of realizing the overall forming of multifunctional integrated composite materials, it effectively guarantees the respective forming quality, functionality and performance characteristics of different functional areas.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a method for composite forming of multifunctional integrated composite materials. Background technique [0002] Composite materials are composed of one or more reinforcements and matrix. Different composite materials can be obtained according to different reinforcements and matrix types. For the same reinforcement and matrix material, due to changes in composition, different composite materials can be obtained. Composite materials, especially for three-dimensional structural composite materials, due to different materials, structures, and forming methods, different composite materials can be obtained, thus exhibiting different performance characteristics. Therefore, in addition to the characteristics of lightweight materials such as high specific strength and high specific stiffness, composite materials also have strong designability, which is also a major advantage of composit...
