In this paper, an improvement is suggested to increase the fatigue life of the isotropic materials combined from glass short fibers and polyester resin materials by adding the reinforcements of powder materials to increase the fatigue strength. Two types of powder materials were investigated, carbon and glass with and without powder reinforcement. The investigation was conducted experimentally and numerically. The experimental program covers the manufacturing the tensile and fatigue samples and evaluate the mechanical properties and the fatigue strength using the different volume fractions and types of powders. The experimental results are compared with those obtained numerically using the finite element technique adopting Ansys program. The comparison has shown a good agreement between the two techniques with a maximum discrepancy of (9.46%). Also, the results indicate that the reinforcement of the composite material by powder materials increase the fatigue limit. Also, the improvement of fatigue life by using the carbon powder is better than that obtained by using the glass powder.
