Studies on mechanical properties of isoro fibers mixed with calcium corbanate reinforced with polypropylene

Abstract

The aim of this study is to investigate the effectiveness of isora fibre mixed with 1% calcium carbonate (CaCO₃) as 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 fibre 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% CaCO₃. Fibre-matrix adhesion will be analysed by mechanical and thermal properties of the composites were evaluated.
