Abstract
The current study examines the mechanical behaviour of Aluminum-Carbon Fiber Reinforced Polymer (Al-CFRP) composites fabricated using compression moulding technique, a novel approach combining lightweight aluminium’s ductility with CFRP’s high strength-to-weight ratio. The polymer composites were fabricated by stacking aluminum alloy sheet of 0.5mm thickness and pre-impregnated by 12 layers of carbon fiber cloth of 200 gsm, with epoxy resin between layers, followed by consolidation under controlled temperature and pressure in a compression moulding setup, ensuring strong interfacial bonding. A comprehensive mechanical characterization was conducted to evaluate the composite’s toughness and structural performance. Results demonstrated that the compression-moulded Al-CFRP composites exhibited enhanced mechanical strength and great stiffness compared to monolithic aluminum, with significant improvements in impact resistance and fatigue life. However, interfacial delamination and fiber buckling were identified as dominant failure modes under extreme loading conditions. This study offers important findings regarding the design and production of non-structural high-performance Al-CFRP metal composites for aerospace, automotive, and defence applications, where weight and formability are crucial than high strength. The results highlight the potential of compression moulding as a viable technique for producing cost-effective, high-strength hybrid composites with tailored properties.
Keywords: Al-CFRP, mechanical characterisation, toughness, metal matrix composites, failure analysis.
