| 摘 要： | 采用红外热波无损检测技术对低速冲击后的碳纤维层合板进行检测和分析,研究了损伤面积与冲击能量之间的关系。对比发现,实验结果与文献结果一致;实验结果说明红外热波不仅可以检测冲击损伤的大小,还可以确定损伤在材料内部绕冲击点沿纤维方向呈旋转方式进行扩展的损伤模式。采用超声C扫描对相同复合材料层合板进行了检测,详细对比了2种检测方法的优缺点,发现对于碳纤维层合板的低速冲击损伤,红外热波检测技术是一种快速、有效、可靠的无损检测技术和评估手段。

| Abstract: | The carbon fiber laminated boards impacted at low velocity were tested and analyzed using infrared thermal wave testing. The relationship between the damage area and impact energy was discussed. The experimental results was consistent with the literature. It is found that infrared thermal wave testing can not only detect the size of impact damage but the expansion of internal damage which revolves round the impact point along the fiber direction. The same laminated boards were tested by ultrasound C-scan. For carbon fiber laminated boards after low velocity impact, infrared thermal wave testing is a rapid, effective and reliable non-destructive evaluation method compared with the ultrasound C-scan. |
