this sensitivity, in this work, mechanical, physical and morphological properties of rubber-based composite friction materials have been performed. We have studied the influence of different proportions of curing agents, phenolic resin and the effect of different rubbers on the final properties of matrices used as friction materials. We have designed our experiments by using the Taguchi method in order to reduce the number
of experiments required. The mechanical and physical properties-such as tensile strength, elongation at break, hardness, swelling properties, degradation temperatures- and morphological behavior were studied. The most effective factors in variation of different properties were reported by analyzing of variance in the Taguchi method. Mechanical and physical properties of such systems were influenced predominantly by variation of resin and sulfur contents. In addition, NBR-based compounds showed higher properties than SBR-based ones.
