Abstract：In view of the technical demand of bamboo industry in China， four key technologies were developed via this 863 program.Under the traditional technology conditions， only the few kinds of bamboo with large diameter level can be available for industrial utilization in a relative lower utilization about 20%～50%.With the application of the patented technology platform， it successfully broke through the difficulty for the bonding problem of the bamboo green and bamboo yellow. Not only the large diameter bamboo， but small bamboo can be full used， and the bamboo culms utilization ratio increase to 95%. High performance bamboo-based fiber composite can be made through the technology platform， such as the framework material for the blade of wind turbine. The implementation of the project promote the upgrading of the bamboo industry in China.

Key Words：Bamboo；Bamboo-based fiber composite；High Performance
