Abstract

Composites of polymer renforced with natural fibres have been widely received great attention by the entire engineering community. Natural fibers that exploredsuch as hemp, sisal, jute and wood fibers provide grater reinforcing capabilities when it perfectly compounded with the polymers matrix. Thus, the potential from the induction of wood flour fibers in the thermoplastics polypropylene (PP)) for the structural application required the materials which can up stand the load in a prolonged duration with unpredictable service environment. This research aims to study and analyze the of different fib1er loading on the mechanical properties and its relationship to the microstructural behavior of the wood flour fik reinforced poiypmpyleae composites. The major raw materials used in this project is polypropylene(PP)as matrix materials wihich based on two type which is the virgin and the rcycle resin and wood flour fiber as reinforcement materials for the composite fabrication. The composite plate were fabricated by usign an exhuder and compression molding machine and were then cut into the specific dimension according to the specific ASTM standsrd of testing. The specimens primarily were tested for the Critical Properties Analysis -Tensile Test. The best oompounding formulation of composite was found at the weight pacentage (wt%) of Wt% of PP matrix and 40wt% of the wood flour fibers for both of virgin and recycle. Further analyses for various mechanical properties of the composite were done accordingly to all composites formulation. The microstructures of tested specimens fracture surface were observed by usign an optical microscope as to understand the fracture behavior, the fiber distribution and the surface morphology and its significant correlation to the mechanical properties studied. The results showed that the increasign of fiber loading had significantly increased the mechanical properties of the fabricated composite. Through the study, the eahancanent of fabricated composite could be applied to the structural engineering applications through the advantage of the mechanical properties of tensile, flexural and impact properties. Conclusively, it is hope that the research will contribute to the development of newly environmental friendly advance materal specifically for the structural application.
