摘　　要：碳纤维增强树脂基复合材料(Carbon fiber reinforced polymer,CFRP)以其优异的物理性能和柔性的结构功能在航空领域应用广泛,而钻削是实现CFRP结构件装配连接的关键制造工艺。由于CFRP具有非均质和各向异性特性,其制孔过程涉及复杂的切屑去除与表面创成机理,极易产生严重的加工损伤。在文献调研的基础上对CFRP切屑去除机理与钻削过程进行简述,然后对CFRP钻孔损伤模式进行分类,重点对CFRP钻孔分层、撕裂、毛刺等缺陷进行综述,阐述了此类缺陷的一般形成机制和评价方法,归纳了工艺条件对CFRP制孔损伤的影响规律。最后,总结了现有CFRP制孔缺陷抑制策略与方法,并指明了其未来发展方向。Carbon fiber reinforced polymers(CFRPs)have been extensively used in the aviation field due to their superior physical properties and flexible structural functions.Drilling is a critical manufacturing process to realize the assembly of CFRP structural parts.Due to the heterogeneous and anisotropic characteristics of CFRPs,the hole-making process entails complex chip removal and surface generation mechanisms,prone to serious machining-induced defects.To date,worldwide scholars have carried out numerous investigations on the defect formation and suppression mechanisms of CFRPs.Based on the comprehensive literature survey,this paper firstly describes the chip removal mechanisms and drilling process of CFRPs,then classifies the CFRP drilling defect modes,and briefly reviews the CFRP drilling defects such as delamination,tearing,burrs,etc.The fundamental formation mechanisms of these defects are investigated,and the impacts of process conditions on the generation of CFRP hole defects are discussed.Finally,this paper summarizes the existing defect suppression strategies for CFRPs and points out the future development directions.
