摘要

以慈竹为试材,探讨浸胶竹纤维化单板的干燥温度对竹基纤维复合材料性能的影响。结果表明:随着干燥温度由70℃升至90℃,复合材料的抗弯强度、弯曲模量和垂直加载水平剪切强度呈现先上升、后下降的趋势,平行加载水平剪切强度和耐水性能逐渐下降。综合考虑板材性能和生产效率,建议工业化生产中的干燥温度设为80℃。

Abstract

Drying glue-impregnated bamboo mats to moisture content around 8%～10% is a key process to make crushed bamboo-mat composites.The authors conducted an experiment to investigate how the drying temperatures could influence the composite’s properties.The results indicated that when the drying temperature was raised from 70 ℃ to 90 ℃,the modulus of rupture,modulus of elasticity,and horizontal shear strength（by vertical loading） of the composite increased and then decreased.However,the horizontal shear strength（by horizontal loading） and water-resistance gradually decreased.Considering the composite properties and product efficiency,the authors suggested that 80 ℃ drying temperature should be used for manufacturing the composite.
