Experimental results showed that the porosity and flexural strength of fiction material were in inverse proportion. Composites with the ratio of resins being 1:3 showed improved thermal resistance. It also showed high friction coefficient at different loads and speeds, while the wear behavior of it was the worst despite its improved thermal resistance. The worn surface topographies of composites showed that tribological properties were related to the plateaus formed on the contact surfaces. (C) 2015 Elsevier Ltd. All rights reserved. 收起
