Abstract

Abstract: The phenolic resin composites modified with different volume ratios of nitrile rubber and boron were prepared to study the effect of resins on the thermal, mechanical and tribological properties of composites. 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. Highlights: Friction materials with hybrid of two resins were prepared. Porosity and flexure strength of fiction material were in inverse proportion. Composite with ratio of resins being 1:3 showed improved thermal resistance. Composite with ratio of resins being 1:3 showed high μ and poor wear resistance.
