Wood plastic composites (WPC) have been produced by compounding meranti wood flour (WF) with polypropylene (PP) copolymer using a twin-screw extruder. The meranti WF content was varied from 30 to 60 wt.%. The mechanical properties, i.e. tensile, flexural and impact of the composites were determined on injection-molded specimens. The tensile fractured surfaces were used to study the morphological properties of the composites. The result shows that the increment in WF content has given a significant improvement in modulus properties but at the expense of strength and toughness properties. A commercial maleic anhydride grafted polypropylene (MAPP) compatibilizer at 5 wt.% was incorporated into the PP40/WF60 formulation. The strength, stiffness and toughness properties were improved significantly in the presence of MAPP. The morphology of the composites was studied by scanning electron microscopy (SEM). The improvement of the fibre-matrix adhesion between the WF and PP matrix as revealed by SEM is believed to be one of the major reasons for the improved mechanical properties.

In this paper, the mechanical properties of carbon fiber polypropylene composites prepared under various process conditions were investigated. Two different types of polypropylene composites were produced by mixing and compressing the mixtures using hot press. The mixture was prepared by mixing polypropylene with chopped carbon fiber and carbon fiber percentage (wt%) was varied. Mechanical properties investigated were tensile test, impact test, bending test and density test. The Scanning Electron Microscopy (SEM) was employed to study the morphology of the composites. The highest tensile strength was obtained for polypropylene (MFI 60) composites reinforced with 10 wt% carbon fiber. The composite also exhibited the best tensile and flexural properties.
