摘要: 分别将纳米三氧化二铝(Al2O3)、纳米二氧化钛(TiO2)、纳米二氧化硅(SiO2)颗粒和碳纳米管(CNTs)填充到环氧树脂(EP)/玻璃纤维(GF)复合材料中,制备了纳米填充EP/GF复合材料,GF的体积含量为30 %。用环块摩擦试验机研究了纳米填充物对EP/GF复合材料的摩擦磨损性能的影响。结果表明,1.0 %(质量分数,下同)的CNTs能够较大幅度地降低复合材料的摩擦因数和磨损率,而纳米Al2O3、纳米TiO2和纳米SiO2颗粒可以明显提高复合材料的耐磨损性能。

Abstract: Nano-Al2O3, nano-TiO2, nano-SiO2, and carbon nanotubes (CNTs) were separately introduced into glass fiber (GF) reinforced epoxy (EP) composites (GF 30 vt %). The friction and wear behavior of the composites under dry condition were evaluated with blockonring friction and wear tester. It showed that 1.0 wt % CNTs could significantly decrease the friction coefficient and specific wear rate of composites, while nano-SiO2, nano-Al2O3, and nano-TiO2 (all at a loading of 1.0 wt %) could slightly decrease specific wear rate of the composites.
