摘要

利用慈竹（Bambusa distegia）制备纤维化竹单板层积材,分析浸胶量对板材力学性能和耐水性能的影响。试验结果表明:随着浸胶量的增加,板材的弯曲强度和抗拉强度降低,弯曲模量和抗压强度的变化不明显,耐水性能增强,水平剪切强度提高。因此,可通过控制浸胶量,进行板材性能的设计,以适应不同用途的需求。

Abstract

The authors developed a new technology for making laminated fibrillated-veneer lumber.They designed an experiment using bamboo（Bambusa distegia） to optimize the processing parameters.The effect of resin impregnation rate on mechanical performance and water resistance was discussed.The results showed that increasing specimen resin content from 7% to 13%,had a negative impact on the average modulus of rupture（MOR） and tensile strength,and a positive influence on the shear strength and water resistance.However,the increase in resin content didn’t affect the modulus of elasticity（MOE） or compression strength.The authors suggested that the panel’s mechanical performance and water resistance could be predicted by controlling the resin impregnation level to meet different application demands.
