A composite material was produced using bamboo fiber soaked into biodegradable poly (vinyl alcohol). To enhance the wettability of specimen, corona discharge was conducted as pre-treatments. The pre-treated specimen was soaked into the poly (vinyl alcohol), then it was compressed and fixed in a airtight atmosphere. Young's modulus in the length direction and flatwise and edgewise shear moduli of the composite material were measured by flexural vibration method, whereas Young's modulus and bending strength were measured by static bending tests. The bending strength of the composite satisfied that of sheathing board, which is determined in the Japanese Industrial Standards as JIS A 5905. Nevertheless, the shear modulus in the thickness direction was so small that it should be improved.
