Mechanical and physical properties of wood polypropylene composites from three Malaysian wood species / Mohd Faizal Mohd Arif
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)...
