    The crucial need for capable vehicles to operate at their maximal performance has urged student teams to discover specific portions to alter, especially in ensuring a lightweight condition. For this purpose, designers have considered the redesigning of spot areas such as the knuckle and the certification of new designs with improved capability and reliability. The objective of this project is to replace the existing knuckle system of a formula student car with a new optimized design which demonstrates greater capability in terms of durability, lightweight feature, uniformity of applied force, and stability, particularly in the cornering performance during a race. Therefore, this project ultimately aims to develop a lightweight knuckle for a KKBD formula student car, applicable to withstand various loads from multiple sources. In addition, the study proposed competent material selection and manufacturing procedures for the knuckle component design. Validation of material selection was carried out via HYPER MESH software to discover the design durability by applying various load paths. The simulation results revealed the improvements of the new knuckle design in comparison to the existing design, wherein the load and stress distribution was more ideal. On the other hand, the stress and load distribution of existing design was more focused on the welding area and demonstrates fluctuation with alternating applied loads which may contribute to fracture during a race performance.

    Epoxy mixed with others filler for thermal interface material (TIM) has been well researched. There are some issues occurs when epoxy is used as matrix material likes non-uniform thickness of thermal interface material produce, time taken for solidification and others. New high-performance phase change material (PCM) using graphene as main material to overcome the existing problem and at the same time to increase thermal conductivity. Three types of composite graphene were used for thermal interface material in this research. The sample that contain 10, 20 and 30 wt. % of graphene was used with different contain of graphene oxide (GO). The thermal conductivity of thermal interface material is both measured and it was found that the increase of amount of graphene used will increase the thermal conductivity of thermal interface material. The highest thermal conductivity is 12.8 W/(mK) with 30 w.% graphene. The comparison between the present thermal interface material and other thermal interface material show that this present graphene composite is a commendable thermal interface material in increasing thermal conductivity and reducing thermal contact resistance.
