摘　　要：针对连续纤维增强的聚合物基复合材料,梳理了常见的缺陷及其产生原因,从缺陷的无损检测方法及其对材料力学性质的影响方面,回顾了最新研究进展。在缺陷检测方面,提高检测精度、加速检测数据处理、发展针对特殊缺陷的检测技术是目前研究的热点。在宏观缺陷对复合材料力学性质的影响方面进行了定性和定量的综述,影响因素主要包括:分层缺陷的面内尺寸、埋深和形状,孔隙缺陷的孔隙率、分布集度和形状,褶皱缺陷的方向、凹凸性和褶皱角等。为纤维增强聚合物基复合材料构件的设计及其可靠性评价提供依据。This paper analyzed the common defects and their causes in the continuous-fiber-reinforced-polymer-matrix composites and reviewed the latest research progress in the non-destructive testing methods of defects and their effect on the mechanical properties of the composites.In the aspect of defect detection,improving detection accuracy,accelerating detection data processing,and developing detection technology for special defects are the hotspots of the current re-search.The effect of macroscopic defects on the mechanical properties of the composites was qualitatively and quantita-tively analyzed.The influencing factors mainly included the in-plane size,buried depth and shape of delamination de-fects,porosity,distribution concentration and shape of pore defects,and the direction,convexity and wrinkle angle of wrinkle defects.This paper provides a basis for the design and reliability evaluation of fiber-reinforced-polymer-matrix composites.
