科爱赛

Therefore , interlayer toughened composites are the excellent candidate materials for primary structure of aircrafts . in this paper , composites modified with particle - interlayer were fabricated . based on the aims of improving compression strength after impact ( cai ) and evaluate damage resistance and damage tolerance , mode ii fracture toughness test and quasi - static indentation test ( qsi ) were conducted
本文采用层间颗粒增韧技术制备试验件，基于提高冲击后压缩强度( cai )和考察损伤阻抗、损伤容限的目的，试验测试了型层间断裂韧性g _ ( c ) 、准静压痕( qsi )试验的分层起始能量和接触力?凹坑深度关系。
