Mechanical Properties of PBS/Bamboo Green Composites Made by Injection-molding
In recent years, from an environmental point of view, there has been an increasing interest in the change to a sustainable society. As one of the solutions of it, the use of natural fiber reinforced biodegradable composites has been proposed. Bamboo is a typical yearly-renewable bio-resource and inherently has an advantage in high growing speed. PBS (polybutylene succinate) used as matrix resin has biodegradable characteristics. This paper describes flexural properties of bamboo/PBS composites prepared by injection molding. As a result, the following conclusions were obtained. When the cylinder temperature of injection molder was 140℃, the flexural modulus was improved with increasing the bamboo powder content. However the flexural strength had the reverse tendency to be decreased with increasing the bamboo powder content. The SEM photomicrograph of the fracture surface for bamboo/PBS composites showed the typical fracture behavior of pull-out fibers without fiber fracture. In addition, there was no sticking of PBS resin on the surface of the bamboo fibers. In addition, the mechanical properties of bamboo/PBS composites were affected by processing conditions, namely higher flexural strength and flexural modulus were obtained at high cylinder temperatures, such as 180℃ and 200℃.
