Biodegradable resin matrix green composites reinforced by ramie fibers are dramatically improved in toughness, if the fibers are treated by means of mercerization. The result of tensile test shows that unidirectional composites using mercerized ramie yarns exhibit larger fracture strain without a significant decrease in strength, in comparison with the composite using untreated yarns. Textile composites using mercerized ramie yarns also show larger impact energy than the composites using untreated yarns. On the other hand, mechanical properties of the composites depend on water content of the matrix. The result of tensile test shows that the textile composite with high water content decreases in stiffness in comparison with the composite with low water content. The composite with higher water content exhibits a higher impact energy.
