Small diameter bamboo and bamboo processing residues were cut into particles; bamboo particles and bamboo mat were constructed into a composite mat; the composite mat was hot-pressed to form a composite board. A study was made of the hot-pressing process for bamboo mat bamboo particle composite boards, taking its hot-pressing time, hot-pressing temperature and glue consumption as the process variables. An analysis of the variance and regression of the test results shows that, among the three variables, glue consumption has the largest effect on every quality index of the product, hot-pressing time has less, and hot-pressing temperature has the least. Based on this, the optimal variables have been determined.Hot-pressing time is 70s/mm, hot-pressing temperature is 170 , and glue consumption is 12%. Prediction and verification of the variables show that these variables are reasonable and helpful in bettering product quality. Advantage of the presented technology was to make full use of character of bamboo mat and bamboo particle, and to raise the rate of bamboo utilization.
