Third East Asian Polymer Conference

IntroductionFiber reinforcement is an obvious way to improve properties of composites, but common reinforcements such as glass, carbon and aramid fibers are neither biodegradable nor easy to incinerate. Natural-fiber-reinforced composites have attracted increasing attention because of their cost effectiveness, availability, low density and biodegradability in association with high specific strength. In recent years, thanks to their high breaking strength, cellulose fibers are excellent reinforcing elements for the preparation of polymer composites . In addition, given their elastic nature, they can be more easily processed than some more rigid fibers such as glass fiber (GF). This paper report the impact, bending strength and modulus of various treated sisal fiber (SF)
