It is known that titanates widely use materials for the Non-Asbestos-and-Organic formulation; NAO has excellent performance such as stability in friction level and low wear for disc brake pads.
In our previous report[
1
], we presented that those brake performance depends on the chemical composition, crystal structure and powder properties of titanates from the dynamometer test results. And we introduced the thrust test machine to evaluate friction materials easily[
2
].
In this study, we have improved the thrust test condition to the repetition of sliding and stopping instead of the continuous sliding. In this interval method, we have controlled the temperature of the friction surface, and have been able to observe a phenomenon of wear that occurs under high temperature in our laboratory.
Then we clarified the correlation between powder characteristics and brake performances. Furthermore, we synthesized a new non-fibrous titanate and found that it indicated to extremely near brake performances in comparison with a fibrous titanate.
