摘要 在扫描电镜下观测了昆虫金龟子外甲壳的微结构特征,发现金龟子外甲壳是一种以几丁质纤维增强角质化蛋白质为基体的层状复合材料,其增强纤维的铺层平行于外甲壳的表面,具有包括螺旋铺层和分叉纤维在内的多种微结构特征,通过与人工合成复合材料的比较,分析了这些结构特征的强韧机理,测量并研究了金龟子外甲壳中的树枝状分叉纤维结构及其拔出力.结果表明,树枝状分叉纤维结构比普通直纤维结构具有更大的拔出力. The microstructure of chafer cuticle was observed by scanning electron microscope. It is found that chafer cuticle is a kind of chitin fiber-reinforced laminate-composite with sclerotized protein matrix. The fiber-reinforced plies parallel the surface of the cuticle. There is a series of peculiar microstructures including helicoidal plies and branched fibers in chafer cuticle. The mechanisms of reinforcement in the strength and the toughness were analyzed by comparing the microstructures of chafer cuticle with the man-made fiber-reinforced composite. Based on the observed microstructures, the fiber pull-out force of branched fiber discovered in chafer cuticle was analyzed. The corresponding experiment was designed and performed, which showed that the pull-out force of branched fiber was greater than that of straight fiber.
