摘　　要：研究了环氧树脂拉伸损伤过程中的声发射特性,进行了直接拉伸断裂、分级加载拉伸断裂和重复加载拉伸断裂3种加载方式的试验,并探讨了声发射特性与增韧剂种类及含量的关系。The acoustic emission characteristics of tensile damage processes in epoxy resin is Studied. Three tests of direct tension fracture, graded loading tension fracture and repeated loading tension fracture are carried out, and the relation between acoustic emission characteristics and the category and content of flexibilizer is discussed.
