Mechanical Characterization Of Epoxy–Glass Fibre– Aluminium Composites Fabricated By Stir Casting

The present project work concentrated on the construction and experimented of a metal matrix composite alloy using epoxy resin, glass fiber, and aluminum particles by employing the stir casting technique. In automotive and aerospace industries, aluminum composite materials are popularly employed due to their superior in strength, higher in malleability, stiffness, excellent in corrosion, wear and lightweight. This present work implies the construction of specimens and analysis of specimens with varying proportions of epoxy resin. The mechanical properties such as strength, hardness and toughness were evaluated with the help of constructed specimens. The experimental values shows a drastic changes on the mechanical properties of the epoxy, glass fibre, and aluminum composite system. In the alloy materials consisting 10% aluminum, 60% Epoxy and 30% Glass fibre, shows the higher epoxy percentage improved matrix stick but moderately falls resistance of impact because of the lower reinforcement ratio. The adjustment of the composition to 50% epoxy, 35% Glass fibre and 15% aluminum yielded a noticeable augmentation in tensile strength, and rigidity of structure, attributable to the raised reinforcement phase. Compared to development of lower aluminium content, the 50% epoxy, 35% glass fibre, and 15% aluminium mixture shows the best stable stiffness, strength, and resistance of impact. It is observed that significant improvement in tensile and toughness aspects of the composite as the results showed that increasing the aluminium and glass fibre content up to optimal levels.
