Abstract

Vacuum-assisted resin infiltration technology (VARI) was used to prepare carbon fiber boards containing superfine copper powder in order to improve the wide application of carbon fiber boards in the automotive industry. The mechanical properties, phase composition and surface morphology of two kinds of carbon fiber board were tested by universal tester, X-ray diffractometer and optical microscope. Afterwards, The tribological performance of two kinds of carbon fiber board was tested on the MRTR friction and wear testing machine under oil lubrication. The results show that the friction coefficient and wear scar width of the carbon fiber board containing superfine copper powder additives are significantly lower than that of the carbon fiber board without copper powder. It indicating that the addition of superfine copper powder can greatly enhance the tribological properties of the carbon fiber board. The reason is the better anti-friction performance and excellent thermal conductivity of superfine copper powder.

含超细铜粉添加剂碳纤维板摩擦学特性研究

为了提高碳纤维板在汽车工业中的广泛应用，采用真空辅助树脂渗透技术(VARI)制备了含超细铜粉碳纤维板。采用万能试验机、x射线衍射仪和光学显微镜对两种碳纤维板的力学性能、相组成和表面形貌进行了测试。随后，在MRTR摩擦磨损试验机上对两种碳纤维板在油润滑条件下的摩擦学性能进行了测试。结果表明:添加超细铜粉的碳纤维板的摩擦系数和磨损痕宽度明显低于未添加铜粉的碳纤维板;说明在碳纤维板中加入超细铜粉，可以大大提高碳纤维板的摩擦学性能。其原因是超细铜粉具有较好的抗摩擦性能和优异的导热性。
