Dynamic Mechanical Behavior of Basalt/aramid Hybrid Fiber Reinforced Uhmwpe Light Weight Composite

ABSTRACT

The main focus of this research is to analyze the physical, mechanical, and dynamic-mechanical properties of the high-performance polymer composite. The composites are fabricated by hot compressing basalt and aramid fibers with UHMWPE (Ultra High Molecular Weight Poly Ethylene) at 200°C temperature and 200 bar pressure. Four different weight fractions of composites were fabricated namely UBA 1 having 70% UHMWPE, 10% basalt and 20% aramid; UBA 2 having 70% UHMWPE, 15% basalt and 15% aramid; UBA 3 having 70% UHMWPE, 20% basalt and 10% aramid; UBA 4 having 70% UHMWPE, 30% basalt and no aramid. The tensile strength, impact strength, hardness, and storage modulus of UBA 4 were found to be greater compared to the other composites. The UBA1 shows the highest flexural strength compared to the other samples. From XRD, the average crystalline size was calculated as 3.02 nm. The SEM image of the composites shows good adhesion of fibers and matrix in both UBA 1 and UBA 4. The dynamic mechanical properties of UBA 4 were also found to be better compared to all four samples for structural application.

摘要

本研究的主要重点是分析高性能聚合物复合材料的物理, 力学和动态力学性能. 该复合材料由玄武岩和芳纶纤维与UHMWPE (超高分子量聚乙烯) 在200°C温度和200 bar压力下热压而成. 制备了四种不同重量分数的复合材料, 即UHMWPE含量为70%, 玄武岩含量为10%, 芳纶含量为20%的UBA 1;UBA 2含有70%超高分子量聚乙烯, 15%玄武岩和15%芳纶;UBA 3含有70%超高分子量聚乙烯, 20%玄武岩和10%芳纶;UBA 4含有70%超高分子量聚乙烯, 30%玄武岩和不含芳纶. 与其他复合材料相比, UBA 4的拉伸强度, 冲击强度, 硬度和储能模量更高. 与其他样品相比, UBA1显示出最高的弯曲强度. 根据XRD计算, 平均晶粒尺寸为3.02nm. 复合材料的SEM图像显示, UBA 1和UBA 4中的纤维和基体具有良好的粘合性. 与所有四种结构应用样品相比, UBA 4的动态力学性能也更好.
