| 摘 要： | 提出了基于光纤图像的复合材料结构内部损伤区域重构方法，根据光纤网络在结构中的排布方式和位置，可定量分析结构损伤域的形状和域内各处的损伤度。层板冲击损伤检测实验中，对所得的离散型损伤度数据进行插值处理，获得的损伤度图形与对半透明复合材料做反向照明的结果吻合，证明了本文方法的有效性。

| Abstract: | An approach is given to the damage region reconstruction within composite structures based on fibre optic image. According to the arrangements and the positions of the fibre optic detecting network, one may quantitatively analyse the shape of the damage region and extents in the structure. The damage extent figure obtained from interpolation of discrete reconstructional data coincides well with the backlighting outcome through semi translucent composites. The result of impact tests on laminates proves the effectiveness of this method. |
