Abstract

Metal Matrix Composites (MMCs) constitute an important class of design and weight-efficient structural materials that are encouraging every sphere of engineering applications and mainly in aerospace applications. The present investigation is focused on formation of a hybrid composite by using industrial waste fly ash and E glass short fibers by dispersing them into AA7075 alloy by Stir casting method. The MMC is obtained for the different compositions of E-glass and Fly ash particulates. The test specimens are prepared to the standard size by turning and facing operations to conduct tensile test and the specimens are subjected to heat treatment. The specimens were tested for tensile test at different loads by using Universal Test Machine. The results are plotted and it is concluded that the MMC obtained has got better tensile strength compared to Aluminum alloy (7075) alone. Further, tensile strength slightly increased with I hour aging heat treatment.
