C f /C-Cu- New Sliding Electrical Contact Materials

Liping Ran; Maozhong Yi; Ke Peng; Lin Yang; Yicheng Ge

[ ]composites were fabricated by infiltrating molten Cu into different preforms prepared by chemical vapor infiltration, resin impregnation and carbonization. The microstructure and properties of the composites were investigated. The results show that Cu in the composites filled the pores and showed network-like distribution. Compared with homemade J204 brush material and certain grade pantograph slider from abroad, the composites have higher flexural strength and better electrical conductivity. The friction and wear properties of the composites are better than that of J204, and closed to that of the abroad material.

Sliding Friction and Wear Behavior of C/C Composites Against 40 Cr Steel

Yicheng Ge; Maozhong Yi; Huijuan Xu; Ke Peng; Lin Yang

In this work, effects of carbon matrix on sliding friction and wear behavior of four kinds of C/C have been investigated against 40 Cr steel ring mate. Composite A with rough lamination carbon matrix (RL) shows the highest volume loss and coefficient of friction, while composite D with smooth lamination/resin carbon matrix (SL/RC) shows the lowest volume loss. The worn surface of composite A appears smooth, whereas that of composite C with smooth lamination carbon (SL) appears rough. The worn surface of composite D appears smooth under low load but rough under high load. Atomic force microscope images show that the size of wear particles on the worn surface is also dependent on the carbon matrix. Keywords : C/C composites, Tribology, Reinforcement, Carbon fibers, Microstructure
