Lumber The study focuses on the effects of wood species, particle sizes and filler loading on the mechanical and physical properties of the wood polypropylene composites. The sawdust was derived from three Malaysian hardwood species; Kelempayan (Anthocephyllus cadamba) , Rubberwood (Hevea brasilliensis) and Simpoh (Dillenia reticulata) were used as filler s in polypropylene composite at 10%, 30% and 50% by weight.
