EXPERIMENTAL STUDIES ON MECHANICAL PROPERTIES OF E-GLASS 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.

Reinforcement of micro and nano material with aluminum alloy (Al7075) metal matrix composite: a review

“…al. [7] analyzed the physical attributes of an Al7075-based reinforced hybrid metal matrix composite of E-glass (1%, 3%, and 5%) and fly ash (2%, 4%, 6%, and 8%). Tensile and compressive strength tests on the specimens were performed.…”

COMPARISON OF MECHANICAL AND MICROSTRUCTURAL EXAMINATION OF AL7075 COMPOSITES REINFORCED WITH MICRO AND NANO B4C

“…The reinforcement can be a ceramic oxide, nitride carbide particulates. These reinforcements are improving the properties of Al7000 series alloys [2], [3], [4]. In an investigation, Al7075 alloy was reinforced with LM 13 aluminum/ B4C by means of liquid metallurgy techniques to find the wear behavior [5].…”

Microstructural Studies of Aluminium 7075-Silicon Carbide-Alumina Metal Matrix Composite

“…The different materials work together to give the composite unique properties. Matrix is continuous phase and reinforcement is non continuous phase which normally harder and stronger [1], [15]. Aluminium matrix composites, a growing number of applications require the matrix properties of super alloys, magnesium or iron.…”

“…Aluminium matrix composites, a growing number of applications require the matrix properties of super alloys, magnesium or iron. Like all composites, aluminiummatrix composites are not a single materials whose stiffness, density, thermal and electrical properties can be tailored to the suitable requirement [1]- [14]. The properties of the composite depend on the properties of reinforcements, size, and its weight fractions [8].…”

“…Metals have a useful combination of properties such as high strength, ductility and high temperature resistance, but sometimes have low stiffness, whereas ceramics are stiff and strong, though brittle [6]. Stir casting technique is the simplest, cost effective and most popular Liquid Metallurgy Route [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. There are two major problems in stir casting technology firstly sufficient wetting of particle by the liquid metals is not achieved and secondly reinforcements float over the surface of the liquid metal.…”
