碳/环氧复合材料拉伸损伤声发射Felicity效应研究

摘要

In order to study the Felicity effect of carbon/epoxy composite,the test program of carbon/epoxy composite [0] unidirectional plate was developed,and then the experiment data was analyzed to study the composite Felicity ratio variation law.The results showed that the composite Felicity ratio tends to be smaller when the damage degree is getting severer,which means that the Felicity ratio can evaluate the damage degree of composite very effectively.%为研究碳/环氧复合材料的Felicity效应,制定了碳/环氧复合材料[0]单向板拉伸试验方案,结合试验数据探讨了复合材料的Felicity比值变化规律。结果表明,复合材料的Felicity比值随损伤程度的增加呈下降趋势,说明利用Felicity比值可以较有效地评定复合材料损伤程度。
