DAMAGE ANALYSIS ON HIGH PERFORMANCE FIBER DURING PREFORM FABRICATION PROCESS

  • Online:2008-04-25 Published:2008-04-25

摘要:

采用声发射方法对玻璃纤维、碳纤维和芳纶纤维三种高性能纤维在直拉、弯拉以及摩擦作用下的损伤破坏过程进行了描述、比较和分析。结合纤维断头电镜照片,对各种纤维损伤的机理进行讨论。

关键词: 高性能纤维, 声发射, 纱线损伤, SEM, 摩擦

Abstract:

In this paper,the damage process of high performance fibers under tensile,bending and abrasive actions is evaluated.Acoustic emission technology was used to represent the fiber breakage history.Combine the data of the AE signals,the tensile strength curve and the SEM photos,the mechanisms of filament breakage were given.

Key words: high performance fibers, acoustic emission, yarn damage, SEM, abrasion
