Abstract

This paper presents experimental results of both quasi-static compression and low-velocity impact behavior for tri-axial bio-composite structural panels using a spherical load head. Panels were made having different core and face configurations. The results showed that panels made having either carbon fiber fabric composite faces or a foam-filled core had significantly improved impact and compressive performance over panels without either. Different localized impact responses were observed based on the location of the compression or impact relative to the tri-axial structural core; the core with a smaller structural element had better impact performance. Furthermore, during the early contact phase for both quasi-static compression and low-velocity impact tests, the panels with the same configuration had similar load-displacement responses. The experimental results show basic compression data could be used for the future design and optimization of tri-axial bio-composite structural panels for potential impact applications.

摘要

本文展示了使用球形加载头对三轴生物复合材料结构面板进行准静态压缩和低速冲击行为的实验结果。制作了具有不同芯部和面层配置的面板。结果表明，与没有碳纤维织物复合材料面层或泡沫填充芯部的面板相比，具有这两种结构之一的面板在冲击和压缩性能方面有显著改善。基于压缩或冲击相对于三轴结构芯部的位置，观察到了不同的局部冲击响应；具有较小结构元件的芯部具有更好的冲击性能。此外，在准静态压缩和低速冲击试验的早期接触阶段，具有相同配置的面板具有相似的载荷-位移响应。实验结果表明，基本的压缩数据可用于未来三轴生物复合材料结构面板在潜在冲击应用方面的设计和优化。
