Abstract: By means of the orthogonal design method, a preliminary study was made to investigate the relationships between 7 structural and technical factors (total board thickness,bamboo sheet thickness,hot pressing time, hot pressing temperature, average density,adhesive level of bamboo sheets,adhesive level of bamboo particles) and strength properties of bamboo composite board (Modulus of Rupture (MOR) and Bonding strength(IB)).The test results show that the total board thickness,the bamboo sheet thickness and the average density are the most important factors affecting the strength properties of bamboo composite board. Hot pressing time and the adhesive level of bamboo particles also affect the strength properties,but the adhesive level of bamboo sheets and hot pressing temperature are of minor effect on the strength properties of bamboo composite board within the test range.
