Investigation of thermal behavior of brake system using alternative materials

During the braking process many undesirable effects can appear that can disturb the safety of all participants in the traffic. It can be considered that using the new alternative friction materials is the key to improve the performance of brake system and reduce the negative effect on the environment. In this research paper, the temperatures and the stresses that appeared during the braking process will be investigated deeply. Different materials for braking disc [cast iron, aluminum matrix composites (AMC), and carbon–ceramics materials (CCM)] were used to achieve the numerical analysis. Finite element analysis (transient structural) was applied to obtain the numerical results. The results showed that the lowest temperature appeared during the heavy-duty braking process when using aluminum matrix composites, while the highest temperature appeared during the braking process when using different types of material for disc brake (cast iron and CCM). Also, the lowest stresses appeared during the braking process when using carbon–ceramics material. This study presents the criterion to select optimal material for braking discs based on the developed approach.
