Research of Nanometer TiO₂/PF Composites and the Properties of Semi-Metallic Friction Material

Abstract:

A type of phenolic resin (PF) was prepared by using TiO₂ nanoparticles modified with KH-550 as composite filler and modifier, and then the composite modified PF were used as adhesive to prepare semi-metallic friction materials samples. TG analysis of the prepared nano-TiO₂ /PF composites was conducted on SETARAM-TG2DSC92216 thermal analyzer that was made in France, and the friction and wear property comparison tests of the samples were carried out on XD-MSM fixed speed friction-wear machine. The results show that the heat resistance of phenolic resin after being compositely modified by TiO₂ nanoparticles can be improved, carbon residue rate increases10% at 600°C；the friction coefficient of the corresponding sample slightly increases；the wear rate clearly decreases at high temperature, and wear rate decreases 10% at 350°C.
