Effect of epoxidised natural rubber on physical and mechanical properties of kenaf core fibre reinforced polypropylene composites

In this research, the kenaf core fibre (KCF) reinforced polypropylene (KCFRPP) composites were fabricated by melt blending using Brabender internal mixer and compression molding with the presence of different amount of epoxidized natural rubber (ENR). Brittleness had been a problem in engineering ma...
