| Abstract In this research, our concentration was to studies the effect of weight fraction of the reinforcement materials(carbon continuous fibers and carbon powder) on the behavior of alternating bending fatigue behavior of the unsaturated polyester matrix(polymeric composite) . The result of this study, reveals that the variation of the weight fraction percentage of reinforcement materials could be affected the fatigue resistance of the composite produced . It have been noticed that increases in the weight percentage fraction of carbon continuous fibers, contributed effectively to improve the fatigue resistance, this reflects the longer fatigue life of the composites, that increase in the fatigue life could be approach to more than (180) times, in the case of using carbon continuous fibers, at the stress level (9MPa), and the percentage of weight fraction (6wt%) . The result obtained of fatigue test in the case of using carbon powder, suggests that the fatigue life depend on the percentage of weight fraction, as the results also reveals some improvement in fatigue life three times and half longer for the weight fraction (2,5wt%), of carbon powder, but the higher weight fraction (6wt%), reduced the fatigue life to a two third compared to un reinforced base matrix . | ||
