Finite Element Analysis and Structural Performance of Composite Vehicle Bumpers

Background: The increasing demand for lightweight, durable, and impact-resistant automotive components has accelerated the adoption of composite materials in vehicle structural applications. Conventional metallic bumpers provide adequate strength but contribute significantly to vehicle weight, which adversely affects fuel efficiency and environmental sustainability. Fibre-reinforced polymer composites, particularly carbon fibre composites, offer a promising alternative because of their high strength-to-weight ratio, corrosion resistance and superior energy absorption characteristics. Finite Element Analysis (FEA) has become an essential tool for evaluating the structural performance of composite bumper systems under different loading conditions enabling engineers to optimize designs while reducing the need for costly experimental testing. Assessing the mechanical behaviour of composite bumper structures is therefore essential for improving vehicle safety, structural reliability and material efficiency.
