摘要/Abstract

摘要： 碳纤维增强树脂基复合材料(CFRP)因其优异的物理性能在航空发动机短舱制造中应用广泛。在应用中,CFRP材料通常需要进行连接与装配,但因其属于脆性材料且具有各向异性,对其进行钻削加工后,容易导致材料应力集中部位产生一定程度的缺陷。为了探究钻削加工工艺对材料孔部质量的影响,国内外对其钻削进行了大量的实验研究,其主要研究内容包括三个方面:切屑形成机制、钻削力、钻削热。本文基于国内外的研究成果,综合概述了CFRP的钻削加工研究现状、CFRP钻削加工后孔部出现的缺陷种类以及CFRP钻削加工工艺的发展趋势。

Abstract: Carbon fiber reinforced plastic(CFRP) composites are widely used in aero engine nacelles for its exellent mechanical properties. The material inevitably requires a lot of connection, but it is a brittle material and anisotropic. After drilling, the stress concentration of the material will have a certain of defects. In order to explore the impact of drilling on the quality of the hole, a lot of researches have been carried out on its drilling process at home and abroad, its process includes three phenomen i.e., a chip formation mechanism, drilling force, drilling heat. Based on the research results from all over the world, this article comprehensively summarizes the drilling mechanism of CFRP, explains the types of defects in the hole after drilling and the development of the drilling process of carbon fiber composite materials.

Key words: carbon fiber, composite material, machining of drilling, defects
