Influence of Heat Variation on Thermal and Mechanical Performance of Al-7075-Based Hybrid Composites

Al-7075 as matrix and E-glass fibre and tungsten carbide powders as reinforcement materials were mixed to develop composite materials. Standard testing techniques were used to assess the mechanical characteristics, such as tensile strength, hardness, and impact resistance. Furthermore, the thermal properties of the composites, such as thermal conductivity and coefficient of thermal expansion, are examined to assess their suitability for applications involving temperature variations. The hardest and greatest tensile yield strength aluminium alloy is the heat-treated AA7075 alloy. Composites’ thermal conductivity declined as the quantity of reinforcement grew because reinforcements low thermal conductivity values made them less efficient. © 2023, The Institution of Engineers (India).
