Abstract

The fatigue properties of braided polyester cord/rubber were studied. The mechanical properties of braided and laminated composites artier fatigue loading were compared with those of cyclic loading of tension, bending and compression. When all composite were fatigued in 30% level of its breaking load, the braided composite showed the highest strength and the lowest reduction rate in tensile elongation. The increase in tensile moduli with extentional fatigue loading of braided composite showed the same rate as those of 5° and 10° ply laminates. The braided composite showed superior fatigue resistant over laminate composites. It is believed that the reinforced cords of the braided composite share the external load than those of laminate composites. The delamination and debonding of the structure during the fatigue didn't show at all in the braided composite.
