Review on wear characteristics of aluminum silicon carbide reinforced with basalt fibre

Abstract

In industrial or research field the most widely used engineering material is aluminium due to their light weight and high strength. The most important factor of high strength-to-weight ratio for Aluminium-Silicon (Al-Si) has made it extraordinarily useful in the area of composite materials because the eutectic composition of Al-Si alloys is α and β structures. Metal matrix composites (MMCs) have proven their prowess, overpowering pure metals in terms of increased mechanical properties. Material mixed in proper ratio with reinforcement can eject increased tensile and hardness properties of the composite. There are different methodologies of fabricating composites like stir casting, liquid infiltration etc., while using these methods with proper parameters. Previous research papers shown that the usage of fly-ash as reinforcement with Al-Si as base metal in between 2-12% is acceptable to indicate improved wear resistance and mechanical properties along with co-efficient of friction and dry sliding behavior of Al-Si-fly-ash metal matrix composite. A dramatic decrease in hardness and tensile properties has been observed in several cases of Al-Si-Fly-ash composites, whose weight percentage of fly-ash goes beyond 10% indicating continuous increment in hardness and tensile properties with certain limitations proposed. To overcome such a problem, it is proposed an addition of basalt fiber in certain weight percentage to test mechanical properties.
