摘    要:为了设计开发轻量型仿生复合材料,考察了甲虫独角仙成虫前翅的结构,得到了甲虫前翅及其小柱结构的简易模型。观察结果表明: 独角仙前翅为具有以小柱为中空层的夹芯层状三合板结构,这种结构为一种轻量型的复合材料板材;小柱中的纤维通过大于90°弯曲与上层及下层中的纤维连续相连接,这种结构对层状纤维强化的复合材料可以极其有效地提高层间的抗剥离性能。

关 键 词:仿生复合材料  甲虫前翅  小柱结构  抗剥离性能  独角仙

Abstract:In order to develop the light-weight biological composite structures, the fore wing structures of beetles, Allomyrina dichotoma, were investigated. As a result, the structural models for both fore-wing of the beetle and trabecular structure were established: (1) the allomyrina dichotoma fore-wing is of sandwich plate structure with the central void layer of trabeculae, and this is one of the typical light-weight composite structures; (2) chitin fibers in trabeculae curved more than 90 degree to connect to the chitin fiber on the upper and the lower lamination, and it is clear that this structure will increase peeling resistance greatly for the laminated composite structures.
Keywords:biomimetics composite material  beetle fore wing  trabecular structure  peeling resistance  Allomyrina dichotoma
