Abstract

Aluminium matrix composites (AMCs) used extensively in various engineering fields due to their exceptional mechanical properties. In this present study, aluminium matrix composites (AMCs) such as aluminium alloy (A356) reinforced with rice husk ash particles (RHA) are made to explore the possibilities of reinforcing aluminium alloy. The stir casting method was applied to produce aluminium alloy (A356) reinforced with various amounts of (2%, 4%, and 6%) rice husk ash (RHA) particles. Physical treatment was carried out before the rice husk ash manufacturing process. The effect of mechanical strength of the fabricated hybrid composite was investigated. Therefore, impact test, tensile stress, compressive stress, and some other tests were carried out to analyse the mechanical properties. From the experimental results, it was found that maximum tensile, and compressive stress were found at 6% rice husk ash (RHA) and aluminium matrix composites (AMCs). In future, the optimum percentages of rice husk ash (RHA) to fabricate the hybrid composites will be determined. Also, simulation by finite element method (FEM) will be applied for further investigation.

Highlights

Composites has become the most widely used materials because of their adaptability in different conditions
The specimens were placed in the grip of the universal testing machine (UTM) machine, and the test was performed by applying tensile load during tensile test, and compressive load during compressive stress test, respectively until failure at room temperature
6 CONCLUSIONS In this study, rice husk ash particles were successfully incorporated in A356 alloy by using stir casting techniques

Summary

Introduction

Composites has become the most widely used materials because of their adaptability in different conditions. Aluminium matrix composites (AMCs) were developed to improve the performance of conventional aluminium alloys which cannot meet the requirement of modern engineering products. Aluminium matrix composites (AMCs) exhibit high strength, high elastic modulus and good wear resistance compared to the without reinforced aluminium alloys. Aluminium matrix composites (AMCs) are increasingly used to produce several components in aerospace, automotive, marine and nuclear industries [1,2,3]. Aluminium matrix composites (AMCs) have emerged as a class of Reference: Hossain, M.
