Effect of the Amount of Water Medium on Short-Cut Rice Straw Based Composite

Abstract:

A series of such composites of poly (vinyl alcohol) and short-cut rice straw were prepared by hot-pressing method at different water medium amounts. And the effects of medium amount on the strength, elongation and hardness of composites were studied. Results indicate tensile strength of composite prepared with 5 mL medium is 119% higher than that with 10 mL medium at formula of 18 g rice straw and 12 g poly (vinyl alcohol). And this kind of strength difference is 98% higher at formula of 15 g rice straw and 15 g poly (vinyl alcohol). Elongation at break is 17.85% when 5 mL medium, 12 g poly (vinyl alcohol) and 18 g short-cut rice straw were used. However, it reaches 21.46% when 10 mL medium was used. The hardness fluctuation range shows no difference when preparation conditions were changed. But samples prepared with 5 mL medium roughly show higher hardness than that prepared with 10 mL medium.
