Effects of Modified-Phenolic on the Tribological Properties of Carbon Fiber Reinforced Phenolic Friction Materials

Abstract:

In order to make clear the effects of modified-phenolic on the tribological properties, three kinds of carbon fiber reinforced phenolic friction materials (cashew-modified phenolic, boron-modified phenolic and chemigum-modified phenolic) were fabricated with the ethyl alcohol as the solvent by vacuum filtration. The tribological properties of samples were studied by the QM1000-II wet friction performance tester. The scanning electron microscope was employed to analyze the micro topography of specimens. Results show that the dynamic friction coefficient and variable coefficient of cashew-modified phenolic friction materials are better than other two materials. The temperature is the most stable during the continuous engagements. The friction torque curve is the smoothest and most symmetrical. Thus, the comprehensive performance of cashew-modified phenolic friction materials is excellent.
