The invention provides an aluminum oxide-quartz mixed fabric reinforced ceramic matrix composite material and a preparation method thereof. The composite material comprises a reinforcing material and a ceramic matrix, the reinforcing material comprises a core layer fabric and surface layer fabrics arranged on the upper surface and the lower surface of the core layer fabric; the core layer fabric is an alumina fiber-quartz fiber mixed fabric; the surface fabric is a quartz fiber fabric; and the ceramic matrix is silicon dioxide. According to the aluminum oxide-quartz mixed fabric reinforced ceramic matrix composite material, the aluminum oxide fiber-quartz fiber mixed layer serves as the core layer, the quartz layer serves as the surface layer, the mechanical property of quartz fibers is prevented from being reduced under the high-temperature condition, and meanwhile the problems that the aluminum oxide fibers are poor in ablation resistance and relatively high in density are solved; and the method has a wide application prospect in the field of hypersonic flight vehicle bearing-heat-proof components.

    本发明提供一种氧化铝‑石英混编织物增强陶瓷基复合材料及其制备方法,复合材料包括增强材料和陶瓷基体;增强材料包括芯层织物和设于芯层织物的上、下表面的表层织物;芯层织物为氧化铝纤维‑石英纤维混编织物;表层织物为石英纤维织物;陶瓷基体为二氧化硅。该氧化铝‑石英混编织物增强陶瓷基复合材料将氧化铝纤维‑石英纤维混杂层作为芯层,石英层作为表层,在避免石英纤维高温条件下力学性能下降的同时,解决了氧化铝纤维耐烧蚀性能差、密度相对较高的问题,在高超声速飞行器承载‑防热部件领域具有广泛的应用前景。
