Abstract

Natural fibers composite play an important role in making eco-friendly products. The present investigation has been made to find tensile strength of hybrid composites fabricated using optimal composition of sisal fiber, glass fiber and alumina. Multi-response optimization has been carried out. The compositions of reinforcements namely sisal fiber, glass fiber and alumina in hybrid composite were prepared by Hand-layup technique. Sisal fiber of 20 Wt.%, 30 Wt.% and 40 Wt.% are chopped into 10mm length, Glass fiber of 20 Wt.%, 30 Wt.% and 40 Wt.% are 10mm length and alumina particles of 2Wt.%, 3 Wt.% and 4 Wt.% are compositions of reinforcement were chosen according to orthogonal array as Taguchi technique(L9). The results have been verified through confirmatory experiments. Experimentations were carried out with the different composition based on L9 process parameters. Based on the experimental observations the maximum ultimate tensile strength was found to be 37.87 MPa for optimised input parameters as 20% of sisal fiber, 30% of glass fiber and 3% of alumina.
