Preparation and Evaluation of Mechanical Properties of Al6061 Reinforced with E-Glass Fiber Metal Matrix Composites

Aluminium alloy materials found to be the best alternative with its unique capacity of designing the material to give required properties. Aluminium alloy metal matrix composites (MMCs) are gaining wide spread acceptance for automobile, industrial and aerospace application because of their low density, high strength and good structural rigidity. In the present work, an attempt is made to prepare and study the mechanical properties of Al6061- E-glass fiber Composite. The Al6061- E-glass fiber having 2wt%, 4wt%, 6wt%, 8wt% and 10wt% were fabricated by liquid metallurgy (stir cast) method. The ingots were subjected to T6 heat treatment to optimize the properties. The composite specimens were machined as per ASTM test standards. The microstructures of the composites were studied to know the dispersion of the E-Glass fiber in matrix. It has been observed that addition of E-Glass fiber significantly improves ultimate tensile strength along with compressive strength and hardness properties as compared with that of unreinforced matrix.
