摘要

碳纤维增强颗粒复合材料由于其优异的功能和机械性能,在商业和军事应用中得到了广泛的应用。在碳纤维增强复合材料中使用纳米填料来改善其功能和力学性能的研究已有报道。然而,需要进行比较研究,以描绘出具有优异功能和机械性能的最佳介电和磁性纳米填料。目前的研究是比较不同的介电和磁性纳米颗粒对碳纤维增强复合材料的电学、力学和热性能的影响。目的是确定一种具有优异的电学、机械和热性能,具有相同重量比的纳米填料,并具有潜在的电磁干扰屏蔽应用。单向复合预浸料分别含有2%(重量)的磁性和介电纳米填料,在实验室开发的UD预浸料制造装置上制备。在介质纳米填料中,含MWCNT纳米填料的复合材料样品表现出最高的电学、热学和力学性能。含氧化钛纳米填料的复合材料在磁性纳米填料中表现出较好的弯曲、电学和热性能。

Effect of Different Dielectric and Magnetic Nanoparticles on the Electrical, Mechanical, and Thermal Properties of Unidirectional Carbon Fiber-Reinforced Composites
Carbon fiber-reinforced particulate composites are immensely used in commercial and military applications due to their excellent functional and mechanical performance. Several studies have been reported to use nanofiller in carbon fiber-reinforced composites to improve their functional and mechanical performance. However, a comparative study was required to depict the best dielectric and magnetic nanofillers with excellent functional and mechanical performance. The current research was performed to compare the effect of different dielectric and magnetic nanoparticles on the electrical, mechanical, and thermal properties of carbon fiber-reinforced composites. The objective was to identify a nanofiller with excellent electrical, mechanical, and thermal properties with the same weight ratio and a potential candidate for EMI shielding application. Unidirectional composite prepregs containing 2% (by weight) of each magnetic and dielectric nanofillers were fabricated on an in-house developed lab-scale UD prepreg manufacturing setup. Among the dielectric nanofillers, the composite samples containing MWCNT nanofiller showed the highest electrical, thermal, and mechanical properties. The composite samples containing titanium oxide nanofillers showed better flexural, electrical, and thermal properties among magnetic nanofillers.
