Composite material reinforced by hybrid fiber preform and preparation method of composite material
The invention discloses a composite material reinforced by a hybrid fiber preform. The composite material is composed of the fiber preform, a composite material interface and a ceramic matrix, the fiber preform is a three-dimensional fabric formed by hybrid weaving of 2-5 kinds of high-performance inorganic fibers, and the matrix is resin, light alloy, carbon and ceramic. A preparation method of the composite material comprises the steps of ceramic slurry preparation, fiber bundle dipping treatment, fiber weaving, three-dimensional integral structure preform forming, preform heat treatment, interface preparation and matrix preparation. The weaving performance of the inorganic rigid fibers is improved, the prepared composite material is good in integrity, high in interlayer bonding strength and not prone to layering, meanwhile, the functions of wave transmission, wave absorption, high-temperature structural material, heat insulation and heat protection are achieved through combination of the hybrid fibers, and integration of the structure and the function is effectively achieved.
本发明公开了一种混编纤维预制体增强的复合材料，由纤维预制体、复合材料界面以及陶瓷基体组成，其中纤维预制体是由2～5种高性能无机纤维混编而成的三维立体织物，基体为树脂、轻合金、碳和陶瓷。该复合材料的制备方法包括：制备陶瓷浆料、纤维束浸浆处理、纤维编织、三维整体结构预制体成型、预制体热处理、界面制备和基体制备。本发明改善了无机刚性纤维的编织性能，制备的混编纤维预制体增强复合材料整体性好，层间结合强度高，不易分层，同时通过混编纤维的组合实现透波、吸波、高温结构材料、隔热和防热功能，有效地实现结构功能一体化。
