Bending Modulus of Elasticity of the Press Forming Composite Material from Bagasse Fiber and Biodegradable Resin

摘要

Bending modulus of elasticity of the composite material from bagasse fiber (remains after sugar cane squeezed) and biodegradable resin was investigated in view of the content of bagasse fiber and the fiber length. The result was validated by short fiber strengthen theory. The result is as followings. Bending modulus of elasticity increased with increasing the content of bagasse fiber. The increase of Bending modulus of elasticity is predicted by short fiber strengthen theory incorporated with the compression ratio of bagasse fiber, which has honeycomb structure in the cross section, was compressed in press forming, makes good agreement with the experimental result. Bending modulus of elasticity decreased when the fiber length of bagasse is under 3mm (aspect ratio=12). This result makes good accordance with the prediction value by the short fiber strengthen theory.
