基于液相法的碳纤维复合材料抗氧化烧蚀技术研究进展

Research Progress in Anti-oxidation Technologies of Carbon Fiber Composites Based on Liquid Solution Method

碳纤维增强陶瓷基复合材料是很重要的高温结构材料,在有氧环境下使用时,氧化烧蚀是导致其失效的首要原因。液相法是实施抗氧化保护的有效手段之一,本文从纤维保护、基体改性、整体涂层三个角度,综述了基于液相法的抗氧化烧蚀技术研究现状,分析了今后发展需要关注的问题。

Carbon fiber reinforced ceramic matrix composites are important thermal structure materials. Oxidation ablation is a dominant cause of degradation in the presence of oxygen. Liquid solution method is an effective means to protect the materials from oxidation. In this paper, research progress in anti-oxidaion based on liquid solution method was reviewed from the point of view of fiber protection, matdx modification, and integral coatings. Then the development trend and key problems were pointed out.
