摘　　要：重组竹是一种新型的可替代硬阔叶材的结构材。对重组竹用于家具制造的干缩与湿胀性进行了研究,结果表明:重组竹的干缩湿胀率均表现出很强的方向性,表现为宽度最大,厚度次之,纵向最小。重组竹出厂时应标明热压时的压制方向,以利用于家具用材加工时进行各方向上加工余量的确定。重组竹干缩系数与柚木相近。在相同近密度下,比几种常见家具木材麻栎等的干缩系数要小,这表明重组竹适于用作家具制造用材。Recombinant bamboo is kind of new engineered timber which can substitute hardwood.This paper researched its shrinkage and swelling properties.The results showed that shrinkage and swelling properties of recombinant bamboo were obviously different in three dimensions.Values of shrinkage and swelling in width were the highest,then followed by thickness and grain direction in turn.The pressing direction should be marked when recombinant bamboo products being out of factory in order to process solid furniture c...
