| Abstract | ||
| In this study, the mechanical properties, fatigue life, and endurance limit values were investigated for composite materials containing natural fiber reinforcement (flax, wool), which were arranged by 0°/90° Angle orientation and a combination of 0°/90° and 45°/-45° angle orientation, then the wool woven mixed by flax woven and unidirectional flax interfered with jute woven. Binary blends containing epoxy and polyurethane at v were mixed at various weight percent (0%, 5%, 10%, and 15 %) vacuum infusion technique was used to prepare the specimens. ANSYS Workbench was used as numerical software to investigate the fatigue behavior and endurance limit values of the unreinforced and reinforced blend. It was found that the weight percentage of 10% polyurethane in the blends was the optimal percentage providing the best fatigue life and the endurance limit value, endurance limit values of wool composite improved when hybridized by flax woven and unidirectional flax interfered with jute woven by 132.895 % and 66.549 % respectively. | ||
