Effect of wood-fiber geometry size on mechanical properties of wood-fiber from Neolamarckia Cadamba species reinforced polypropylene composites.

摘要

Using natural wood-fiber as reinforcement in commercial thermoplastics is gainingudmomentum due to its high specific properties and renewable resources. In this study, the effect ofudwood particle geometry size on mechanical properties of thermoplastics composite wasudinvestigated. The wood species that has been chosen is Kelempayan species (Neolamarckiaudcadamba) and reinforced with polypropylene using fiber geometry size of 75 and 250 μm.udThermoplastic composites were produced from two types of ratio (30:70 and 10:90) betweenudwood-fiber and polypropylene. Static bending and tensile strength were tested. The resultudshowed that wood-fiber from 75 μm geometry sizes with ratio of 30:70 between wood-fiber andudpolypropylene was most suitable in producing thermoplastic composites. The geometry sizes ofudwood particle as well as the ratio between wood-fiber and polypropylene were found to influenceudthe mechanical properties of the thermoplastic composites.
