摘要
纤维增强陶瓷基复合材料具有高比模量、高比强度、低热膨胀系数、耐高温、耐腐蚀和耐磨损等许多优良的力学性能。这些优良的特性使其在航天航空等领域的应用日益增加。但纤维增强陶瓷基复合材料具有非均质性、各向异性、硬度高和脆性大的特点,是一种典型的难加工材料。因此,有必要对纤维增强陶瓷基复合材料的加工机理进行深入的研究。本文系统介绍纤维增强陶瓷基复合材料的传统加工和非传统加工研究现状,并对各种加工工艺方法的发展趋势、优缺点、适用范围、存在问题及相应解决方法进行总结和概括。和传统加工方法相比,非传统加工方法具有比较明显的优势,是当前发展的主要方向。
Fiber-reinforced ceramic matrix composites have many excellent mechanical properties for their high specific modulus,high specific strength,low coefficient of thermal expansion,high temperature resistance,corrosion resistance and wear resistance.Due to these properties,fiber-reinforced ceramic matrix composites have been widely applied in aerospace and other fields.However,fiber-reinforced ceramic matrix composites are difficult to machine due to their heterogeneity,anisotropy,high hardness and brittleness.Therefore,it is necessary to conduct in-depth research on the machining mechanism of this kind of composites.This paper systematically reviews the research status of conventional machining method and non-conventional machining method of fiber-reinforced ceramic matrix composites.It also generalizes the development trend,advantages and disadvantages,application scope,existing problems,and corresponding solutions of various machining methods.Compared with the conventional machining method,non-conventional machining method has obvious advantages,which is the main direction of development at present.
