The invention discloses a high-strength and high-toughness TaxHf1-xC-based composite material and a preparation method thereof. According to the TaxHf1-xC-based composite material, TaxHf1-xC ceramic is used as a substrate, and metal Ta is used as a toughening phase; the TaxHf1-xC-based composite material is of a layered structure, the TaxHf1-xC ceramic layer and the metal Ta layer are arranged ina laminated mode, and the upper surface and the lower surface of the TaxHf1-xC-based composite material are both TaxHf1-xC ceramic phases. The preparation method comprises the steps of designing the structure of the TaxHf1xC-based composite material, paving and filling raw materials according to the designed structure, sintering at high temperature and the like. The TaxHf1-xC-based composite material provided by the invention has the characteristics of high strength and high toughness, can be used in an extreme thermal environment, and can be used as a high-temperature valve of a solid rocketengine, a wing leading edge of a hypersonic flight vehicle and other components. The preparation method provided by the invention is simple and convenient in process and large in material structure design space.
本发明公开一种高强高韧TaxHf1‑xC基复合材料及其制备方法，该TaxHf1‑xC基复合材料以TaxHf1‑xC陶瓷为基底、以金属Ta为增韧相；TaxHf1‑xC基复合材料为层状结构，TaxHf1‑xC陶瓷层与金属Ta层叠层排布，且所述TaxHf1‑xC基复合材料的上表面和下表面均为TaxHf1‑xC陶瓷相。该制备方法包括设计TaxHf1‑xC基复合材料的结构、按设计的结构铺填原料和高温烧结等步骤。本发明提供的TaxHf1‑xC基复合材料具有高强高韧的特性，可在极端热环境下服役，用作固体火箭发动机的高温阀、高超声速飞行器的机翼前缘等部件。本发明提供的制备方法工艺简单方便，材料结构设计空间大。
