摘要

为了研究一种新型的仿生节能夹芯板——甲壳虫板（BEP），研究了不同聚氯乙烯泡沫密度和高厚比的短玄武岩纤维增强环氧树脂复合材料BEP和蜂窝板的压缩力学性能。通过观察内外环蜂窝壁的失效模式，揭示了芯体结构、泡沫密度和高厚比的耦合作用机理。该研究可为轻质夹层结构的设计提供有益的指导，并加速BEP在工程中的应用。

The compressive mechanical properties of honeycomb plates and beetle elytron plates with different foam densities and height-to-thickness ratios

To investigate a new type of bionic energy-saving sandwich plate—the beetle elytron plate (BEP), the compressive mechanical properties of short basalt fiber reinforced epoxy resin composite BEPs and honeycomb plates with different polyvinyl chloride foam densities and height-to-thickness ratios were investigated. The mechanism of the coupling effect of the core structure, foam density and height-to-thickness ratio was revealed by observing the failure mode of the outer and inner ring honeycomb walls. This study can provide useful instruction for designing lightweight sandwich structures and accelerate the application of BEPs in engineering.
