An overview of mechanical and corrosion properties of aluminium matrix composites reinforced with plant based natural fibres

Abstract

Abstract Many researchers have become more interested in utilizing plant based natural fibre as reinforcement for the fabrication of aluminium matrix composites (AMCs) in recent time. The utilization of these environmentally friendly and cost effective plant based natural fibre is necessitated to avoid environmental pollution. The desire for cost-effective and low-cost energy materials in automotive, biomedical, aerospace, marine, and other applications, however, is redefining the research environment in plant based natural fibre metal matrix composite materials. As a result, the goal of this review study is to investigate the impact of agricultural waste-based reinforcements on the mechanical properties and corrosion behaviour of AMCs made using various fabrication routes. Processing settings can be modified to produce homogenous structures with superior AMC characteristics, according to the findings. Plant based natural fibre ash reinforcing materials such as palm kernel shell ash, rice husk ash, sugarcane bagasse, bamboo stem ash, and corn cob ash can reduce AMCs density without sacrificing mechanical qualities. Furthermore, efficient utilization of plant based natural fibre reduces manufacturing costs and prevents environmental pollution, making it a sustainable material. Brittle composites , unlike ceramic and synthetic reinforced composites, are not formed by plant based natural fibre reinforcements. As a result of our findings, plant based natural fibre AMCs have a high potential to replace expensive and hazardous ceramic and synthetic reinforced-AMCs, which can be used in a variety of automotive applications requiring lower cost, higher strength-to-weight ratio, and corrosion resistance.
