studies on isora fibers mixed with 1% ricinoleic acid reinforced with polypropylene

The aim of this study is to investigate the effectiveness of isora fiber mixed with 1% ricinoleic acid as a reinforcement for polypropylene (pp) thermoplastic matrix. isora fibers were subjected to mercerization prior to blending with pp in order to obtain good interfacial adhesion with the matrix. a pp/isora composite has been prepared by melt blending of pp with 5%, 10%, 15%, 20% alkali treated isora fiber in co-rotating twin screw extruder. the extruded strands are pelletized and then injection-moulded to obtain specimens. the optimum compositions of the pp/alkali treated isora composites were mixed with 1% ricinoleic acid. fiber-matrix adhesion will be analysed by mechanical and thermal properties of the composites which were evaluated.
