| Abstract Because of the increasing importance in recent yeary of using composite material generally , and polymeric composite material in particular in different advanced industrial application , an experiment work was carried out to investigate the most important characteristics which are related to the polymeric composite materials . In this research unsaturated polyester resin (up) was used as a (matrix) for composite material while the reinforcement used was Cotton fiber . The specimens of composite material were prepared by hand lay-up from fiber with volume fraction of (0% , 5% , 15% , 20% , 30% , 40%) the mechanical tests included (Flexural strength) nodules , tensile strength , and Impact ) Flexural strength and modulus were found to increase with cotton constriction , where as tensile strength and Impact were found to decrease at higher concentrations . | ||
