Morphology and Graphitization of the Worn Surface of C/C Composite with Rough Lamination/Smooth Lamination/Resin Carbon as Matrix Precursor

Abstract:

We study systematically the morphology and graphitization of the worn surface of C/C composite with rough lamination/smooth lamination/resin carbon (RL/SL/RC) as matrix precursor tested by using M2000 wear tester with a couple of Cr-coated 40 Cr steel. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) analyses indicate that the worn surface of RL/SL/RC is integrated. Particles with the size of 100~300 nm could be found on the worn surface. The leaning-angles of the particles against the sliding direction on the worn surface are between 30 ° and 50 °. Raman laser spectrum (RLS) analysis reveals that, after the wear test, the graphitization on the worn surface of RL/SL/RC decreased with the increase in load, but graphitization of the fiber kept constant and that of the boundary increased up to 150 N. The surface graphitization of different components became closer and closer with the increase in load.
