Composite is a combination of two or more chemically distinct and insoluble phases. The composites consist of one or more discontinuous phases (reinforcement) embedded in a continuous phase (matrix). Composite Material is mainly used to improve the properties of material. The present paper reviews various types of composite material used in different industrial and commercial applications. study of various manufacturing technique for preparation of composite material are described. Various mechanical testing techniques are presented to check the characterisations. Composites are extensively used because of their high strength to weight ratio. Moreover, the use of versatile synthetic fiber in preparation of the composites with concern toward the environment issues to develop composites using glass fiber reinforced. In the present paper, glass fiber reinforced epoxy composites are synthesized considering three factors viz. epoxy to hardener ratio, curing temperature and fiber percentage to study the tensile behavior of the composites. The experiments were conducted based on Taguchi L9 orthogonal array considering three design parameters. The experimental data were analyzed using Taguchi optimization technique and optimum combinations of process parameters values for tensile strength was determined. Analysis of variance (ANOVA) was carried out to obtain the significance of factors affecting the tensile strength. It was observed from the analysis that the percentage of fiber has more significant effect on tensile strength at 95% confidence level.
