Abstract

Nowadays, strong international demand for composite is driving expansion of industrial-scale and automotive industry. Due to unstable properties of Carbon Fiber (CF), the modifications of their properties are necessary to improve. The versatility of polypropylene in general purpose products was addressed to support green environmental by recycling materials. Recycle carbon fiber was used as filler for Polypropylene and as a primary matrix material with different formulation in order to improve their physical and mechanical properties. The optimum compounding formulation of the material compound was observed at the combination of polypropylene and carbon fiber based on 100 wt. % of the polypropylene (PP) and different carbon fibers filler loading at 3wt%, 10wt% and 20wt%. In order to improve the interfacial interaction between polypropylene and carbon fiber, maleic anhydride was used at composition of 3wt% and 5wt%. Polypropylene and carbon fiber were blend together by using Internal Mixer and the composition were fabricated into thin sheets using a Hot Compression Molding machine. The compound undergone a few testing includes Pin-On-Disc, Shore Hardness Type D and Optical Microscope to characterize the properties of PP/rCF composites. Based on the study, the higher the weight percentage of rCF will improve the properties of its hardness. Furthermore, for testing tribology, the addition weight percentage of recycle carbon fiber will improved the wear resistance and coefficient of friction of the PP matrix.
