Abstract: 
A composite material is made of resin and fibers with different mechanical properties. The mechanical property of the composites is a mixture of the mechanical properties of the resin and fibers. The main goal of this research is determining the optimum fiber volume fraction of unidirectional composites to achieve the best strength properties. Based on the results obtained in this research, the compressive strength in the fiber direction of the composites is used to measure the optimum fiber volume fraction. In this research this idea is studied using the failure theories and the results are evaluated by conducting experiments, based on ASTM standard, on E-Glass/Epoxy composites. After comparing the analytical and experimental results, the optimum fiber volume fraction of the composites is defined. Also, by applying the strength reduction factor, the allowable deviation from optimum fiber volume fraction is achieved. This result can be used as a quality control criterion.
