亜麻繊維と炭素繊維を用いた繊維強化プラスチックの衝撃吸収部材

（落錘試験による軸圧縮エネルギ吸収性能の基礎的検討）

Carbon fiber reinforced plastics (CFRP) are used in a variety of industrial products. Because of the high heat resistance of CFRP, disposal and recycling processes for products used in its applications are not well established and many challenges remain. A flax fiber-reinforced plastics using natural fibers such as hemp and coir have been proposed to replace glass fiber and carbon fiber used in fiber-reinforced plastics. Authors focused the flax fiber reinforced plastic as impact absorption materials used for crash box in automobiles. In this report, we manufactured a specimen made of flax fiber and carbon fiber prepreg and evaluated impact absorption performance by drop weight test.
