Jute fiber reinforced polypropylene composite: effect of chemical treatment by benzenediazonium salt in neutral medium

Jute fiber was treated with o-, m-, and p-hydroxybenzenediazonium salts in neutral media. These modified and raw jute fibers were used to prepare jute-polypropylene (PP) composite containing 20, 25, 30, and 35% by weight fraction. Mechanical properties of composites were studied. It was found that the increase in fiber content reduces the mechanical properties of jute-PP composite. However, treated jute fiber imparts better mechanical properties to jute-PP composite than the raw jute fiber. o-Hydroxybenzenediazonium salt (o-HBDS) treated jute-PP composites are found to be the best composite from the point of view of mechanical properties.
