Product Development And Performance of Reinforced Metal Matrix Composite Brake Disc: Modelling, Simulation And Multi-Criteria Decision Making Technique

Article history : Demand for lightweight and durable components for automotive applications, such as brake discs, is increasing. This has led to the emergence of new designs for brake discs using metal matrix composite (MMC), which offers high strength – lightweight performance and high thermal conductivity. Therefore, this research aims to develop a new brake disc material and design with higher braking capability and is capable of replacing the existing one. Additionally, modelling, simulation, and multi-criteria decision-making (MCDM) techniques were used to select the best design of the MMC brake disc. The results showed that Design 6 with angular grooves has the best performance at dissipating heat and is capable of reaching the highest temperature of 284.66°C with the lowest deformation value of 0.589 mm. Therefore, it is the best alternative due to its highest normalized priority of 0.2742. The combination of MMC as the new material and design has the ability to improve thermal and structural performance, thereby enhancing the vehicle's braking capability.
