本文用同步辐射计算机断层扫描技术研究了碳纤维-环氧树脂层合板的0度层裂。该技术允许直接三维观察损伤。微观机制，如钉扎和桥接已被观察到在橡胶增韧，树脂丰富的地区。与0度分裂相关的裂纹张开和剪切位移已被量化，这项工作表明，这种技术可能是特别有用的，用于确定复合材料损伤周围的全场应变图。(c)2008 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
In situ synchrotron radiation computed tomography has been used to investigate 0 degrees ply splits in a [90/0](s) carbon fibre-epoxy laminate. This technique allows for direct three-dimensional observations of damage. Micromechanisms such as pinning and bridging have been observed in rubber-toughened, resin-rich regions. Crack opening and shear displacements associated with 0 degrees splits have been quantified and this work demonstrates that this technique may be particularly useful for determining full-field strain maps around damage in composite materials.
