Abstract
Short carbon fiber (SCF) reinforced Polypropylene (PP) composites were fabricated using twin-screw extruder followed by injection molding process. The SCF used is of 7-9 mu m diameter and 90 mu tm length (SCF90). SCF were loaded at two different percentages, 15%wt and 35%wt. Different %wt loading of compatibilizer (Maleic Anhydride grafted Polypropylene (MAPP)) ranging from 0 to 4 %wt were used. For 15 wt% loading, higher %wt of MAPP increases the ductility but the strength and modulus remain at the same level as without MAPP. Optimal %wt was found to be at 2%wt of MAPP. For 35 %wt loading, no change on the ductility observed but slight drop in the modulus and strength at 4 %wt loading.
