Comparative Experimental Measurements of Jute Fiber/polypropylene and Coir Fiber/polypropylene Composites as Ionizing Radiation

摘要

Jute and coir fiber-reinforced polypropylene (PP) composites (45 wt% fiber) were prepared by compression molding. Composites were fabricated with irradiated jute fiber/irradiated PP and irradiated coir fiber/irradiated PP at different doses (250-1,000 krad). It was revealed that jute-based composites had better mechanical properties as compared to coir-based composites. Interfacial shear strength of jute/PP and coir/PP systems was measured by using the single-fiber fragmentation test. Scanning electron microscopy investigation shows poor fiber matrix adhesion for coir-based composites than that of jute-based composites. Water uptake and soil degradation tests of the composites were also performed.
