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.

Hydrothermal depolymerization of DGEBA/EDA epoxy resin was carried out in a stainless autoclave at temperatures of 270°C to 350°C in H2O medium. The effect of the factors catalyst, temperature and time on the depolymerization was researched. The products of depolymerization were analyzed qualitatively and quantitatively by means of GC/MS and GC. The results indicated that the main depolymerized products were phenol, p-isopropylphenol and bisphenol-A (BPA). The epoxy resin composite based on glass fiber and the solid residue after reaction using catalytic hydrothermal depolymerization technology were analyzed by SEM. Also, the depolymerization kinetics of epoxy resin with 3% catalyst and no catalyst were researched and the activation energy was calculated.
