Application of advanced biO₂composites in wind blades

Bamboos , a kind of bio-materials , grow fast and have good mechanical behaviors. The properties of outside st rip of bamboo are better than those of inside , so the grading process was developed , which can make the laminate bamboo st rip lumber (LSBL) of grading A , B , C and D. The advanced biO₂composites , compared with othermaterials , can replace GFRP and wood/ epoxy , and can be used in wind blades as a new generation of materials.This new materials have many advantages , such as renewable , less dissipation of energy , low cost , no waste and theworn2out product s can be disposed easily.
