Effect Of Thermal Aging On The Fatigue Behavior Of Natural Rubber

Abstract

—This paper investigates the thermal aging effects on the fatigue life duration of natural rubber using volumetric test specimens under uniaxial loading condition. All samples were thermally aged in an oven at 70 ℃ and 120 ℃ in 48h and 96h. Then, the uniaxial tensile tests were performed at room temperature. It shows that with the aging temperature and time increase, the fatigue life of natural rubber decreases. The fracture areas also have different macro morphology.
