EXPERIMENTAL STUDIES ON MECHANICAL PROPERTIES OF EGLASS SHORT FIBRES & FLY ASH REINFORCED AL 7075 HYBRID METAL MATRIX COMPOSITES

Abstract

Conventional monolithic materials have limitations in achieving good combination of strength, stiffness, toughness and density. To overcome these shortcomings and to meet the ever increasing demand of modern day technology, composites are most promising materials of recent interest. Metal matrix composites (mmcs) possess significantly improved properties including high specific strength, specific modulus, damping capacity and good wear resistance compared to unreinforced alloys. Among the mmc’s aluminum composites are predominant in use due to their low weight and high strength. The key features of mmc’s are specific strength and stiffness, excellent wear resistance, high electrical and thermal conductivity. The present investigation aims at the development of aluminium based e-glass and flyash particulate reinforced hybrid metal matrix composites. The test specimens are prepared as per astm standard size by turning and facing operations to conduct tensile and compression test.

Fabrication and Characterization of Aluminum (Al‐6061) Matrix Composite Reinforced with Waste Glass for Engineering Applications

“…This concept of multiphase composites provides exciting opportunities for designing an exceedingly large variety of materials with property combinations that cannot be met by any of the monolithic conventional metal alloys, ceramics, and polymeric materials [3,4]. The composites, especially metal matrix composites (MMCs), have received considerable attention in the field of materials research due to their lighter weight, higher strength, more wear resistance, and greater fatigue and dimensional stability than conventional composites [5][6][7][8]. MMCs are increasingly becoming a new class of material in device applications because their properties can be tailored through the addition of selected reinforcements [9,10].…”
