In this paper, an analysis of a carbon fibre reinforced plastic (CFRP) torsion bar in a Formula 1 car is discussed. The use of composite torsion bar is rather uncommon on in the application of Formula 1 car. Composite structures are usually applied to produce a lighter design while maintaining the strength. Composite structures are considered as modern materials that may act as an upgrade to the conventional metal alloys in present engineering applications. In a Formula 1 car, the load applied on a torsion bar could cause fatigue due to its frequent usage. Maintaining safety and weight are crucial for Formula 1 cars. Replacing metal components with composite could be beneficial. Torsion bars are vital components on a Formula 1 car’s suspension. The torsion bar acts as a spring to absorb bumps by utilizing its stiffness when it experiences torsion. A comparison between the stresses of the torsion bar for both composite and metal alloy is conducted in the present work. This is done by simulating a torsion test on a torsion bar model with predetermined conditions. The comparison of the torsion test simulation results the for both materials by means of Finite Element Method (FEA) is shown in some details.
