摘　　要：采用成熟的竹木复合集装箱底板制造工艺,根据不同的组坯方式,用竹帘及杨木单板压制成竹木复合板和竹木复合层积材。该工艺的创新点在于只将杨木单板浸胶,而竹帘直接干燥铺装,以减少人工操作对竹帘的破坏。通过研究两种板的抗弯性能,发现其顺向抗弯性能非常好,可将其分别作为集装箱底板和建筑结构用材。此外,针对竹木复合板性能不稳定的问题提出了改进方案。Using mature bamboo-wood composite container floor manufacturing process and according to different assembly modes, bamboo-wood composite plate and laminated bamboo-wood composite lumber are made by using bamboo curtains and poplar veneers. The innovation point of the process is that only the poplar veneer is dipped in the glue and the bamboo curtains are directly dried and paved to reduce the damage to bamboo curtains caused by artificial operation. The study on the flexural performances of the two kinds of boards shows that they have excellent forward bending performances and can be directly used as materials for container floors and building structural material. Besides, an improvement plan for solving the instability of bamboo-wood composite boards is presented.
