The aim of this study was to produce mahogany (Swietenia macrophylla) wood flour filled polypropylene (both recycled and virgin) composites and to determine the effects of maleic anhydride-grafted polypropylene (MAPP) on the interfacial compatibility, density, and other mechanical properties of the resulting composites. Approximately 40 wt% of mahogany wood flour, and 60 wt% of polypropylene, 3 wt% of MAPP, 1.5 wt% of zinc stearate, and 1.5 wt% of wax were used during composite manufacturing. Test specimens were manufactured using extrusion and injection molding processes. The flexural, tensile, impact, and hardness properties of all specimens were determined. Scanning electron microscopy was used to study the morphology and interfacial compatibility of the filler in prepared composites. The test results showed that MAPP use and the filler rates affected the density and mechanical properties of test specimens.

In this study, wood plastic composites (WPC) material were fabricated with wood flour and polyvinyl chloride (PVC). To improve the interfacial compatibility between the wood flour and the PVC, silane method (SM) and tianate method(TM) were used to treat the wood flour, maleic anhydride copolymerized PVC with dicumyl peroxide. The effects of wood flour content, surface treatment on the mechanical properties of WPC materials were investigated. Fracture surfaces of tests specimens were analysis by SEM. Test results indicate that WPC material with wood flour treated by SM or TM together with PVC copolymerized showed good mechanical properties.

Tensile Impact

Recycled polypropylene/microcrystalline cellulose (rPP/MCC) composites were prepared by adding different loadings of maleic anhydride grafted polypropylene (MAPP) coupling agent. The tensile, impact and morphological properties of the composites were investigated. The obtained results show that the tensile and impact strengths of the composites were significantly enhanced with the addition of MAPP loading from 2 to 5 wt%, as compared with unfilled rPP/MCC composites. However, it was found that at low filler content, different amounts of MAPP resulted in no appreciable change in the tensile strength and modulus. Moreover, dynamic mechanical analysis (DMA) results indicated that, increasing the amount of MAPP loading from 2 to 5 wt% in rPP/MCC provide better stiffness of the composite compared to those neat rPP and neat PP. Field emission scanning microscopy (FESEM) has shown that the composite, with MAPP loading, promotes better fibermatrix interaction.

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.

This paper presents the study of mechanical properties of short pineapple leaf fibre reinforced polypropylene composites. Pineapple leaf fibre (PALF) is one of them that have also good potential as reinforcement in thermoplastic composite. It is the objective of the current research to characterize the mechanical properties of treated and untreated composites of PALF reinforced polypropylene (PP) composite with four different volume fractions of pineapple leaf fiber (PALF) was fabricated, (5 vol%, 10 vol%, 15 vol% and 20 vol%).  The study of this PALF-PP composite demonstrates that bulk density of the composite decrease as the volume fraction increased. From the study about impact strength toward the fibre loadings, impact strength and energy absorbed increase as the volume fraction of fibre increased. Untreated PALF gives greater impact strength than treated PALF. From the experiment conducted on impact test and scanning electron microscopy experiment, untreated fibre produce greater impact and absorbed energy than treated fibre. Until 20% of PALF, result showed strength of the composite still rising to prove that 20% of fibre will fabricate finest fibre loading for the PALF-PP composite was observed from the scanning electron microscope (SEM) micrograph as an evidences on compatibility mechanical properties at the intersectional region of composite.
