Investigation on Interaction Mechanism of Components in Fiction Materials Doping Rare Earths

摘要：

Semi-metal friction material was applied widely in brake process of traffic and dynamical system. The friction materials with rare earth additive were manufactured by heating press molding process. The effects of different reinforcing fibers and adhesives on the properties of the materials were studied by changing the formula. The results showed that the friction materials with YSM resin adhesive and hybrid fibers (Kevlar pulp and steel fiber) had higher and more stable friction coefficient and lower wear rate. Semi-metal friction materials with rare earths formed iron-rich surface layer in the worn surface, and the mechanisms of wear had obvious differences at typical temperature ranges.
