摘要

本文主要对芳纶/环氧复合材料在高速冲击下的损伤面积进行了研究。使用数字x射线摄影和主动脉冲热成像技术对撞击标本(8至28层芳纶)进行尸检分析。使用了两种类型的弹丸:9毫米鲁格FMJ和0.357马格南FMJ。开发了两种专用算法对获得的热像图进行后处理,并将结果与x射线片上直接测量的损伤直径进行了比较。因此,对这三种方法的输出进行了比较和讨论。

Comparison of non-destructive techniques for impact damage area assessment in aramid/epoxy composites
This research focused on the assessment of the damaged area on aramid/epoxy composites subjected to high velocity impact. Digital X-ray radiography and active pulsed thermography techniques were used for performing post-mortem analysis of the impacted specimens (8 to 28 aramid layers). Two types of projectiles were used: 9 mm Luger FMJ and 0.357 Magnum FMJ. Two types of dedicated algorithms were developed to post-process the thermograms obtained and the results are compared with the damaged diameter measured directly on the X-ray radiographs. The output of the three methods are therefore compared and discussed.
