摘要
研究了芳纶/环氧复合材料在承受拉伸载荷时的损伤与断裂行为。发现不同损伤类型表现出不同的声发射特性,从声发射信号的某几种关联图中可以较好地判断损伤发生的类型,并可根据某些声发射特征参量值对临界承载值进行合理的确定。
The damage and fracture of composite material of epoxy-matrix reinforced by Kevlar-fiber in thestate of trending is researched in this paper.It is discovered that different damage has different acoustic emission(AE)feature,different stage of damage in composite can be differentiated by some relational graphs of signal acousticemission,and critical loading value can be decided reasonably by some AE parameters.
