Comparative studies of mechanical and interfacial properties between jute and bamboo fiber-reinforced polypropylenebased composites

ABSTRACT: Jute and bamboo fiber-reinforced polypropylene (PP) based compo-sites (50wt % fiber) were fabricated by compression molding. Tensile strength (TS), bending strength (BS), tensile modulus (TM), and bending modulus (BM) of the jute-reinforced PP composite were found to be 48, 56, 900, and 1500MPa, respectively. Then, bamboo fiber-reinforced PP-based composites (50wt % fiber) were fabricated and the mechanical properties evaluated. The TS, BS, TM, and BM of bamboo-reinforced PP composites were found to be 60, 76, 4210, and 6210MPa, respectively. It was revealed that bamboo fiber-based composites had higher TS, BS, TM, and BM compared to jute-based composites. Degradation tests of the composites (jute fiber/PP and bamboo fiber/PP) were performed in soil at ambient conditions for up to 24 weeks. It was revealed that bamboo fiber/PP composite retained its original mechanical properties higher than that of jute fiber/PP composite
