抄録

Since CFRP has light weight and strong characteristic compared with conventional structural materials. On another front, wood has been used in various forms such as furniture, house building. Instead of its light weight and low cost characteristics, compared with metal, strength is relatively low and often causes a brittle failure. So the application of wood to the structure for automobile, etc. is restrictive. In this study, the improvement of the mechanical properties of wood which is 10w strength and 10w toughness is explored. The composite plate of wood with thin CFRP layer is actually prepared. The result of having done bending testing is reported. By adding thin CFRP layer on 20mm wood plate, bending strength rises 130%. Furthermore by adding foamed material between thin CFRP layer and 20mm wood plate, absorbed energy rises 150%.
