本文以疏解竹柬和速生杨木单板为对象,系统研究竹木配比对板材主要物理性能的影响规律,并初步得出优化的热压工艺参数。试验结果表明:在热压温度和热压时间一定时,不同竹木配比下静曲强度随竹束所占比例的增加先增后减,而后又出现回升;弹性模量和内结合强度呈现上升趋势,分别增长了19.5％和115％;板材的吸水厚度膨胀率基本制在2％以内,且竹木配比的变化而有规律的变化。根据竹木复合板材性能测试结果取竹木配比1:1来获得较优化的生产工艺。

　　Using the bamboo bundles and fast-growing poplar veneer as experimental material, the ratio of bamboo and poplar on the main physical and mechanical properties of wood-bamboo composite was investigated in this study, and the optimal press process was achieved.The results show that: the press temperature and time was not changed, with increasing the ratio of bamboo to poplar, there were a decreasing about MOR after increasing, and then it raises again, the MOE and IB increases 19.5% and 115% respectively.The reach also showed that the absorb...
