This paper introduced characteristics and sorts of bamboo composite materials, elaborated processing technology and technological features of different bamboo composite materials, analyzed current status of bamboo processing industry in China, brought up some problems, and to look into the research direction and future of bamboo composite materials in China.
Bamboo composite material is a kind of composite materials which are manufactured by using bamboo as raw materials through some certain processing technology.
Initial moisture content of raw materials mainly is more than 40%, so they have to be dried.
Because the thermal conductivity of bamboo than wood materials is lower, so the hot pressing time should be slightly longer than wood materials.
