A Study of the Influence of Porosity and Resiliency of a Paper-Based Friction Material on the Friction Characteristics and Heat Resistance of the Material

One of the major characteristics of paper-based wet friction materials used for clutch plates and brake bands in automotive automatic transmissions is represented by their resilient and porous properties.

This specific characteristic is considered to govern the tribological behavior between a paper-based friction material and a mating steel surface.

In this paper, the effects of porosity and resiliency on the friction characteristics and heat resistance of paper-based friction materials were studied.

Significant direction was obtained by the experimental data of this study, which may be adapted to the design of friction plate materials.
