摘　　要：竹材是一种变异性非常显著的天然材料,本文采用分级方法研究了竹层积材的吸水膨胀率。结果表明:竹层积材是一种低湿胀性材料,顺纹、径向和弦向上均远低于木材和LVL。经过对竹木材构造的分析,解释了竹层积材低湿胀性的原因。利用竹层积材低湿胀性的特点,可以开发湿环境和干湿交替环境下使用的系列产品。Bamboo is a variable natural material, so the bamboo strands need to be graded. The swelling properties of grading bamboo strand lamination were studied.The results showed that the grading bamboo strand lamination is a low-swelling material. The swelling of parallel to grain, radial and tangential is lower than that of timber and LVL. This paper explains the reason for low swelling through analysing the structure of timber and bamboo. By using its low-swelling property serial products can be developed, which can be used in humid and dry-humid alternate environments.
