Abstract
Abstract
Materials for friction used in brakes should fulfill many requirements, such as stable friction performance in all conditions, lower change in the friction coefficient, high wear resistance and low wear rate. In this study, three different compositions were produced to investigate the effects of each composition and its manufacturing parameters. Three different compositions, which are called standard, fly ash and sisal fiber mixture, were produced to be compared with existing commercial heavy-duty truck brake lining. These compositions were homogeneously mixed and hot molded at different pressures and temperatures. The post-curing effect was also investigated in some of the samples. The wear and friction tests were performed using a friction tester. The density and hardness of the samples were also analyzed in relation to compositions and manufacturing parameters. The coefficient of friction and wear behavior was compared with a commercial heavy-duty truck brake lining. The results suggest that there is a high potential in the samples investigated for commercial trucks applications of brake lining products that are highly suitable from the environmental and cost reduction view.
