摘要
研究了聚乙烯(PE)纤维胶丝束拉伸损伤过程中的声发射(AE)特性,确定了PE纤维胶丝束拉伸损伤过程中不同损伤阶段的AE特性,得到了不同损伤类型的AE参数特征。研究发现,判定PE纤维胶丝束失效的依据是出现幅度大于90 dB、持续时间大于1042μs的AE信号。
The acoustic emission（AE） characteristics of tensile damage processes in PE fiber was studied by means of testing.By using AE multi-parameter analysis,the AE characteristics of different damage phases were defined and AE parameters of different damage types were obtained.The research indicated that the determinant rule of PE fiber invalidation occured when the AE extent was more than 90 dB and the duration was more than 1042 μs.
