Utilization of RHA in development of green composite material using RSM

Abstract

In the present investigation, rice husk waste from rice mill was utilized in the development of aluminum based green metal matrix composite. Response surface methodology (RSM) was employed to develop green metal matrix composite by considering tensile strength as a response. Rice husk ash (RHA) was used as primary reinforcement material and B4C was used as a secondary reinforcement material in the development of composite. Microstructure results showed a uniform distribution of RHA and B4C in aluminum based matrix material. The optimum combination of reinforcement parameters was found to be RHA weight percentage of 7.8%, RHA preheats temperature of 231.12âC, B4C preheats temperature of 435.24âC and B4C wt.% of 6.67% respectively to achieve a tensile strength of 249.867 MPa.
