摘要
报告了用热致液晶对玻璃纤维增强环氧树脂材料表面裂纹疲劳过程进行的检测，成功地给出了裂纹周围的温度场分布．
This poper reports on the use of thermochromic liquid crystals for the detection of surface cracks on a glass fibre reinforced epoxy composite material which was subjected to cyclic loading.The results obtained were very successful with the liquid crystals giving a clear indication of the temperature distribution around the fracture site.
