For the purpose of applying biomass sources to various industrial products, a bamboo powder composite was developed by injection molding. The matrices used for the composite were a cornstarch-based biodegradable resin (CP) and polypropylene (PP). To improve compatibility between the powder and matrices, alkali-treatment using NaOH solution was carried out for the powder. The results showed that tensile strength of the PP matrix composite increases largely if the alkali-treated powder is used as reinforcement, as compared to the composite reinforced by the untreated powder. The CP matrix composite was also improved in strength, though the degree of increase was not so effective. There may be an optimal NaOH concentration to increase mechanical properties.
