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
