Abstract

Effect of hard particle angularity on frictional coefficients and grit embedment of brake material was investigated. Silicon carbide, silica sand and garnet were used with drag and stop mode test. The spike parameter quadratic fit (SPQ) method was applied to characterize the particles angularity. Results showed that particles angularity exhibited a great influence in modifying the effective contact, wear generation and friction coefficient. Good correlation between pad specimen weight loss and grit embedment was found. Signs of formation and disintegration of contact plateaus correlated well with angularity, suggesting the grit embedment role as wearing mechanism.
