Technical Abstract: Cellulose obtained from a variety of agricultural sources was utilized as the fiber-reinforcing dispersed phase in biodegradable starch-based composites. Materials included rice straw, kenaf, linen, hemp, cotton, Whatman filter paper, and Avicel PH101. Fiber properties, such as crystallinity, particle size and content of noncellulosic impurities were taken into account regarding the effectiveness of these fibers as reinforcing agents. Further, the fiber surface properties were assessed with electrokinetic analysis as well as by microscopic methods. Thermal and mechanical characteristics of the composite materials were studied. As reinforcing agent, cotton proved to be more difficult to process than fibers containing small amounts of lignin and other impurities. Linen and Hemp fibers showed fairly high tensile moduli and good cohesion properties.
