Recent developments in Al7075 hybrid composites and study on its microstructure and mechanical characteristics

Abstract

Hybrid composites are formed by incorporating more than one reinforcement into the parent alloy and these are considered to be one of the significant materials used for aerospace, automobile, defence applications. Even nano hybrid composites are also evolving as materials to be considered with prominence. Aluminum metal matrix hybrid composites especially Al7075 hybrid composites are known for superior strength to weight ratio and good wear resistance, that's why those are considered as most useful materials in the field of mechanical applications. Ease of manufacturing, low cost of production paved the way for aluminum hybrid composites to emerge itself in to one of the potential material for future applications in aerospace, automobile, defence sectors. In order to develop aluminum hybrid composites several reinforcements were been added along with the metal matrix. Reinforcements enhance the mechanical, physical and micro structural characteristics of the hybrid composites. Mechanical properties would get enhance with varied wt % of reinforcements. This article provides an overview on recent developments on aluminum metal matrix hybrid composites.

Analysis of the use of composite materials for further application in the support of mine workings

“…Механічні властивості композитних матеріалів залежать від фізикомеханічних властивостей фазових складових та дефектів кристалічної будови [36]. В композиційних матеріалах із волокнистою будовою фази зміцнення дефекти кристалічної структури накопичуються переважно в матричній фазі та на границях розподілу між фазовими складовими.…”
