Effect of Orientation of Basalt Fiber Skin on Damping Performance of PALF/Epoxy Hybrid Composites

ABSTRACT

The objective of the present study is to develop a low-cost hybrid composite using pineapple leaf fiber obtained from agro-waste as core and high modulus basalt fiber produced from volcanic rock as skin to analyze the impact of basalt fiber orientation (skin) on the tensile, flexural, and damping properties of the composite. Different composite samples were fabricated with PALF at 0º (aligned with the longitudinal direction) and with different basalt fiber orientations using the hand layup method. The findings showed that the laminate with PALF and basalt aligned in the longitudinal direction had the best flexural properties and storage modulus, while the sample with the basalt fiber oriented at 90° had the best tan delta (damping). The maximum variation in glass transition temperature due to change in fiber angle was noticed as ~3°C.

摘要

本研究的目的是以从农业废弃物中提取的菠萝叶纤维为芯材，以火山岩中提取的高模量玄武岩纤维为外皮，开发一种低成本的混杂复合材料，分析玄武岩纤维取向（外皮）对复合材料拉伸、弯曲和阻尼性能的影响. 用PALF在0º (与纵向对齐）和不同玄武岩纤维方向，使用手铺法. 结果表明，PALF和玄武岩纵向排列的层合板具有最好的弯曲性能和储能模量，而玄武岩纤维取向度为90%的层合板具有最好的弯曲性能和储能模量. 有最好的棕褐色三角洲（阻尼）. 由于纤维角度的变化，玻璃化转变温度的最大变化为~3ºC
