Abstract
Effects of the rolling ratio, the stress amplitude and the test temperature on the fatigue property of the rolled PP/LCP blends have been examined from the variation of dynamic viscoelasticity factor during the fatigue process. The results show that : (1) Under a low rolling ratio (within 40%), the specimen was softened and easily to generate heat. Therefore, it ruptures for the ductile fracture earlier than the unrolled specimen. (2) For the 60% rolled specimen, with the increase of stress amplitude level the E' decrease while the tan δ, Ts, ΔL, Ld increase. The ductile fracture tendency became more evident. But, the specimens had not ruptured under all stress level and test temperature. It shows an excellent fatigue resistance property. (3) The resistance to fatigue becomes better as the test temperature decreases. Especially, it shows a high ductile, high strength and high fatigue resistance even under -10°C when the blends material, which lost the ductile property even under the room temperature, is pressed at 60%.
