Abstract

The optimal distribution of the reinforcing fibers for stiffening hollow cylindrical composites is explored using the linear elasticity theory. The spatial distribution of the vascular bundles in wild bamboo, a nature-designed functionally graded material, is the basis for the design. Our results suggest that wild bamboos maximize their flexural rigidity by optimally regulating the radial gradation of their vascular bundle distribution. This fact provides us with a plant-mimetic design principle that enables the realization of high-stiffness and lightweight cylindrical composites.

摘要

利用线性弹性理论探索了用于增强空心圆柱复合材料的增强纤维的最佳分布。天然设计的功能梯度材料野生竹子中维管束的空间分布是该设计的基础。我们的结果表明，野生竹子通过最佳调节其维管束分布的径向梯度来最大化其抗弯刚度。这一事实为我们提供了一种仿植物设计原则，可实现高刚度和轻质的圆柱复合材料。
