【 摘 要 】

The use of lignocellulosic materials as reinforced polymer composite has been in great demand during the last decade due to some of its advantages. The lignocellulosic material may be in the form of wood flour or cellulose fiber, both of which have different properties and structures due to effects of the resulting composite product. This study aims was to compare lignocellulosic materials as reinforcing agent in polypropylene composite, i.e in the form of wood flour or cellulose fibers. The characterization conducted were the physical and mechanical properties of the composite. The characteristics of lignocellulose materials were investigated using FTIR and XRD analysis. Cellulose fibers were obtained by pulping with an alkaline solution, followed by bleaching treatment. The results showed that the chemical treatments could increased the crystallinity of the fibers, therefore resulted in an increase of physical and mechanical properties of polypropylene composites.
