摘要:

連續(xù)纖維增強(qiáng)陶瓷基復(fù)合材料由纖維、陶瓷基體和界面三元素構(gòu)成。由于具有密度低、耐高溫、抗腐蝕、抗輻照、強(qiáng)度高等特點(diǎn)，且在斷裂過程中表現(xiàn)為非脆性斷裂特征，成為一類重要的結(jié)構(gòu)材料，在一些極端服役環(huán)境中體現(xiàn)出不可替代的發(fā)展趨勢，備受世界各國關(guān)注。近 20 多年來，歐美、日本等發(fā)達(dá)國家一直將陶瓷基復(fù)合材料的研發(fā)作為重點(diǎn)方向，并投入巨資進(jìn)行研究。本文針對新一代高推重比航空發(fā)動機(jī)熱端結(jié)構(gòu)、高超聲速飛行器熱防護(hù)結(jié)構(gòu)以及新一代核能系統(tǒng)結(jié)構(gòu)部件對適用于極端服役環(huán)境陶瓷基復(fù)合材料的需求，結(jié)合目前的研究現(xiàn)狀，從組成、結(jié)構(gòu)設(shè)計(jì)和制備的角度淺析適用于不同服役要求的陶瓷基復(fù)合材料的構(gòu)建，為材料在極端環(huán)境下的性能優(yōu)化提供借鑒。

Abstract:

Continuous fiber reinforced ceramic composite (CMC) consists of fiber, ceramic matrix and interphase. It is a kind of promising material that can be used under extreme environment due to its low density, heat resistance, corrosion resistance, radiation resistance and high strength. Ceramic matrix composite has been drawn much attentions and intensive studied by western countries. In order to meet the application requirements of ceramic matrix composite served as thermal-structural materials in extreme severe environment, such as new generation turbine engine, hypersonic vehicle and new generation nuclear fusion reaction, the design of CMC was discussed based on the composition, structure and fabrication process. This review is expected to give suggestive guidelines for the performance optimization of CMC under extreme service conditions.
