The invention discloses a thermal protection needling composite material with a heterogeneous structure and a preparation method, and belongs to the field of functional compounding. In the thermal protection needled composite material with the heterogeneous structure, a layer A is obtained by alternately laying carbon fiber plain cloth and a carbon fiber web, a layer B is obtained by alternately laying alumina fiber plain cloth and an alumina fiber felt, and a layer C is an alumina film; the layer A, the layer B and the layer C are needled to obtain a needled prefabricated body, and then the needled prefabricated body is impregnated with aluminum oxide slurry and sintered through a chemical vapor deposition process to obtain the thermal protection needled composite material with the heterogeneous structure. The thermal protection needling composite material with the heterogeneous structure prepared by the invention can simultaneously have high temperature resistance and heat insulation performance.

    本发明公开了一种非均质结构热防护针刺复合材料及制备方法,属于功能复合领域。本发明的非均质结构热防护针刺复合材料中A层是以碳纤维平纹布与碳纤维网胎交替铺层得到,B层是氧化铝纤维平纹布和氧化铝纤维毡交替铺层得到,C层为氧化铝薄膜;本发明的A层、B层和C层之间通过针刺得到针刺预制体,再通过化学气相沉积工艺、浸渍氧化铝浆料,烧结,得到非均质结构热防护针刺复合材料。本发明制备的非均质结构热防护针刺复合材料可以同时兼顾耐高温和隔热性能。
