Tribological Properties of Carbon Fiber Epoxy Resin Composite and Polyimide Material at High and Low Temperatures

Abstract

Carbon fiber epoxy resin composite and polyimide material are likely to be applied to pulley-guideway system of the new satellite antenna. Their tribological properties have effects on the motion characteristics of the pulley-guideway system. To master the tribological properties of carbon fiber epoxy resin composite and polyimide material, this paper carries out tests of tribological properties and wear behavior of carbon fiber epoxy resin composite and polyimide material at 130°C and 30°C. Carbon fiber epoxy resin composite is used as the grinding specimen and polyimide material is used as the counter-grinding specimen. Tribological properties of this material pairs is studied under diverse linear velocity and external loads. The results show that friction coefficient of this material pairs is stable under different conditions, especially at 30°C. Meanwhile, wear behavior of this material pairs is mainly affected by ploughing of surface roughness at low temperature, while by surface micro-spalling at high temperature.

Friction and Wear Behaviours of Polyimide Composites Against Steel Ball Under Rolling-Sliding Compound Motion

“…Due to its high thermal and chemical stability, excellent wear resistance, and good self-lubricity, polymer materials has widely used as the structure materials in human joints, bearings and other industrial elds [1][2][3][4]. Among them, especially polyimide and the related composite materials have received extensive attention because of their extra superior mechanical properties and high temperature resistance [5][6][7][8].…”
