【摘要】 采用浸胶玻璃纤维布强化方法制造杨木胶合板模板。以杨木胶合板模板的弹性模量为指标,分析玻璃纤维布浸胶量、偶联剂用量、玻璃纤维布上下面单板涂胶量等的影响。在试验确定的优化工艺条件下,模板的纵、横向弹性模量和纵、横向静曲强度分别提高23.6%、35.4%、24.5%和65.3%。更多还原

【Abstract】 Poplar(Populus deltoides) veneers were used to make plywood for concrete forms.With the modulus of elasticity as an index,the effects of glass-fiber cloth,with the following conditions,were studied: various resin contents,addition of a silicone coupling agent,and resin spread at the interface between the veneer and the glass-fiber cloth.Under the optimum parameters obtained from the experimental results,the MOE∥,MOE⊥,MOR∥ and MOR⊥ were improved by 23.6%,35.4%,24.5% and 65.3%,respectively.更多还原
