| 摘 要： | 经过若干世纪的选择进化, 生物自然复合材料昆虫外甲壳的细观结构高度优化, 使其具有种种优良的性质。本文研究了昆虫外甲壳的细观结构特征, 这些结构特征为人工合成复合材料提供了一些有益的启示。按在昆虫外甲壳中发现的双螺旋铺层结构和纤维绕孔铺层结构, 用玻璃纤维和环氧树脂制备了仿生铺层复合材料, 比较实验表明, 仿生铺层复合材料比常规铺层复合材料有更高的强度和断裂韧性。

| Abstract: | Through untold centuries of evolutionary development, the insect exoskeleton has become a highly optimized structure suited to a variety of demanding duties. In this study, the structure of the exoskeleton of the insect was investigated for structural characteristics that may prove beneficial to advanced composite efforts. The arrangements of plies discovered in insect exoskeleton were applied to the biomimetic design and synthesis of the glass fiber reinforced epoxy composites. It was shown experimentally that the fracture toughness and the intensity of biomimetic plies are higher those that of conventional ones. |
