本研究的目的是探讨碳纤维布的脆性行为是否可以减轻。实现这一目的的一种方法是遵循生物结构，即所谓的仿生学。本研究以螳螂虾为研究对象。其前足的特征结构是甲壳素纤维在改变角度的同时堆叠。进行了三点弯曲试验，并记录了载荷和位移。在试验过程中，用摄像机观察试样直至断裂。最后，通过比较，对螺旋层合CFRP试件的弯曲特性进行了评价。结果表明，螺旋层合结构可以有效地改善CFRP的脆性。
The purpose of this study is to investigate if the brittle behavior of CFRP can be mitigated. A way to achieve the purpose is to follow a biological structure, so-called biomimetics. In this study, mantis shrimp is selected. The characteristic structure of its forefoot is that chitin fibers are stacked while changing spirally their angles. Three point bending tests were carried out, and load and displacement were recorded. During the tests, the specimens were observed until fracture with a video camera. Finally, bending characteristics of helicoidally laminated CFRP specimens were evaluated through comparison. It was found that the brittle behavior of CFRP could be mitigated by a helicoidally laminated structure.
