Friction Characteristics of CuTi4O9 as Base Agent

In the previous paper, we reported friction characteristics of K2Ti4O9 as a base agent of disk-type brake pad. The use of K2Ti4O9 seems to be effective in increasing the friction coefficient, but it causes abrasion and a great deal of wear. In this study, the authors investigated the characteristics of a new base agent using processed K2Ti4O9 in HCl, then in Cu(OH)2 so that K2Ti4O9 was transformed into CuTi4O9. In friction materials using CuTi4O9 as abase agent of disk-type brake pad, thermal decomposition of the base agent and combination with Phenol-resin occurs at almost the same temperature. Because thermal conductivity of CuTi4O9 is high, phenol-resin decomposition is difficult. Consequentry, CuTi4O9 will be effective decreasing the amount of wear.
