摘要
陶瓷基复合材料(CMC)具有密度低、耐高温的优异特性而被视为新一代航空发动机的战略热结构材料,其制备工艺、性能设计及其在燃烧室和涡轮等热端部件的应用已成为现阶段航空发动机研究领域的热点。然而,由于编织特征导致的各向异性特性,给CMC在热端部件的应用和加工带来巨大挑战。本文总结了有关陶瓷基复合材料在航空发动机热端部件上的应用研究现状和存在的挑战,提出未来CMC热端部件精细化热分析发展建议。
Ceramic Matrix Composites(CMC),with low density and high thermal resistance,has been regarded as the potential thermal structure material for the future. Currently,the preparation technology,performance-based design and the application of the CMC are highlights in aeroengine and the rocket engine research field. Nevertheless,the anisotropy properties of CMC due to the internal structural and the difference between matrix and fibers lead to big challenges and difficulties for the hot components design and manufacturing. The present paper aims to analyze the development of CMC applications in aeroengine based on a brief review of the relevant public research work. Meanwhile,some suggestions for CMC components thermal analysis were proposed for the potential research.
