摘要:
我国丛生竹资源丰富,但其加工利用的开发远远落后于毛竹。为促进丛生竹的开发利用,以3种常见的大径丛生竹油簕竹、越南巨竹和麻竹为材料,加工成竹篾层积材,并对板材的物理力学性能进行测定。结果表明,3种竹篾层积材的含水率在7.02%~7.96%之间,符合《竹篾层积材》规定的标准6%~8%;最小静曲强度为118.40,基本达到标准规定的120;最小冲击韧性为112.86 kJ·m-2,均大于标准规定的110 kJ·m-2,即产品主要物理力学性能基本能达到或超过产品规定的指标,板材的胶合性能优良,各物理力学性能间具有较密切的相关性。因此,在生产实践中,开发和利用这3种大径丛生竹是可行的。

Abstract:
Facing the problem that the big sympodial bamboo resources are not used sufficiently, the authors probed into the possibility of mading three kinds of big sympodial bamboo, Bambusa lapidea McClure, Dendrocalamus yunnanicus et D.Z.Li and Sinocalamus latiflorus Munro into laminated bamboo strips and studied their physical and mechanical properties. The results showed that the physical and mechanical properties of the three kinds of laminated bamboo strips reached the requirement of the standard of laminated bamboo strips with the moisture content of 7.02%~7.96%, the minimum MOR(modulus of rupture)of 118.40 and the minimum pushing strength of 112.86 kJ·m-2, showing good bonding quality. The physical and mechanical properties of the three kinds of laminated bamboo strips had good relativity with each other. Therefore, it is feasible to process and utilize laminated bamboo strips using big sympodial bamboo in practice.
