Evaluation of the effect of the novolac resin ratio on the high temperature performance of the brake pads

The resin is a widely used binder in the brake pads. Determining the optimum, resin ratio is important for the brake pad to show the best wear and braking performance. In this article, the impression of the novolac resin ratio (15% and 30%) on the perfor-mance of the brake pads at high temperatures was studied. Friction experiments of the brake pads were performed according to ASTM G99–95a test standard in Pin-on disc test device at 350 °C. The average friction coefficients obtained in the friction tests of 15% and 30% novolac resin samples at 500 rpm rotation speed, 350 C temperature, and 10 N load were 0.151 and 0.308, respectively. With the increase in the novolac res-in ratio, the hardness, density, and thermal conductivity of the brake pads have in-creased.
