Design and Performance Analysis of Sustainable Hybrid Composites for Impact Absorption and Lightweight Applications

This study explores the mechanical and structural properties of a novel hybrid composite composed of recycled tyre rubber, ceramics, and wood. The investigation focuses on key parameters, including energy absorption, compressive and tensile strength, and density, to evaluate the composite's suitability for diverse applications. The impact energy absorption test revealed that Sample A, comprising 50% rubber, 25% ceramic, and 25% wood, exhibited the highest energy absorption capability, with an average of 68 J. This superior performance is attributed to the inherent elasticity of rubber, which effectively dissipates impact forces. In compressive strength tests, Sample B (30% rubber, 50% ceramic, 20% wood) demonstrated the highest resistance, achieving a compressive strength of 72 MPa. The significant contribution of ceramic to structural rigidity underpins this result, making it ideal for load-bearing applications. Tensile strength analysis identified Sample C (40% rubber, 30% ceramic, 30% wood) as the optimal performer, with a tensile strength of 35 MPa. This composition balances flexibility and strength, leveraging rubber's elasticity and ceramic's durability Density analysis highlighted Sample D (30% rubber, 20% ceramic, 50% wood) as the lightest composition, with a density of 0.89 g/cm3, making it suitable for lightweight applications. These findings suggest the composite's potential for automotive, construction, and protective gear applications, offering a sustainable and eco-friendly alternative to conventional materials while maintaining robust mechanical properties.
