Thermal And Dynamic Mechanical Properties Of Grafted Kenaf Filled Poly (Vinyl Chloride)/Ethylene Vinyl Acetate Composites
Faculty of Engineering University of Malaya
The effects of kenaf and poly (methyl methacrylate grafted kenaf on the thermal and dynamic mechanical properties of poly (vinyl chloride), PVC and ethylene vinyl acetate, EVA blends were investigated. The PVC/EVA/kenaf composites were prepared by mixing the grafted and ungrafted kenaf fiber and PVC/ EVA blend using HAAKE Rheomixer at a temperature of 150 degrees C and the rotor speed at 50 rpm for 20 min. The composites were subjected to Differential Scanning Calorimetric (DSC), Thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA), Fourier transform infrared (FTIR) and Scanning Electron Microscopy (SEM) studies. The DSC data revealed that the crystallinity …
