Mechanical properties of rice straw particle/HDPE composites

The rice-straw particle /HDPE composites were made by compression molding process. Effects of the content of the rice-straw particle, the dosage of the titanate coupling agent and the time of hot-press were analyzed. Mechanical properties of the composites were tested, such as MOR, MOE by universal material testing machine. The result showed that rice-straw particle /HDPE composites have relatively good mechanical properties. The effect of the content of the rice-straw particle on the MOR and MOE of rice-straw particle /HDPE composites are very significant. The mechanical properties of the composite material improved by adding titanate coupling agent. The optimized processing conditions are that the content of the rice-straw particle is 50%, the dosage of the titanate coupling agent is 3%, the time of hot-press is 4 min.
