Composite forming method of multifunctional integrated composite material

Abstract

The invention relates to a composite forming method of a multifunctional integrated composite material. The composite forming method is characterized in that a plurality of functional areas and corresponding transition areas are obtained by partitioning according to different functional requirements of parts; the transition areas are manufactured by adopting a 3D printing or a flexible guide three-dimensional weaving forming process according to the shape requirements of the functional areas, and the transition areas with adjacent functional area guide template information on two sides are obtained; Z-direction reinforcement arrays of the adjacent functional areas are respectively formed on two sides of the transition areas; all functional areas are woven and formed, and a multifunctionalintegrated composite material prefabricated body is obtained; and single matrix material or multiple matrix materials are synchronously impregnated and cured, so that composite forming of the multifunctional integrated composite material is achieved. According to the composite forming method, different quantities and varieties of the reinforcing bodies, the matrix materials and the appropriate forming processes are adopted for the different functional areas to carry out synchronous weaving forming; and meanwhile, the preformed transition areas can isolate the two functional areas on the two sides, the various matrix materials can be simultaneously impregnated, and on the basis of achieving the integral forming of the multifunctional integrated composite material, the respective forming quality, functionality and performance characteristics of the different functional areas are effectively guaranteed.

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...
