Abstract
An experimental study was conducted to investigate the influence of thermo-oxidative ageing on the tensile properties of PVC/ENR/KCP composites. Sodium dodecyl sulfate filler treatment was also carried out to evaluate the effect of filler treatment. The composites were prepared by melt compounding using Haake Polydrive internal mixer at 140 °C and 50 rpm. Compression-moulded samples were subjected to fracture surface morphology analysis and thermo-oxidative ageing for 3, 5 and 7 days. Thermo-oxidative ageing test indicates that after 3 days of exposure to heat, tensile strength increases, which is due to the further cross-linking reaction. With further exposure for 5 days and 7 days, the tensile strength is reduced probably due to the reduction in flexibility of the cross-link, which affect the stress distribution in the composites.
