摘　　要：巴沙木又称轻木,是制造风电叶片常用的材料之一。目前风电叶片用巴沙木含水率通常控制在12%以下,含水率过高将使叶片生产时产生缺陷。为研究不同含水率的影响,本文选取市售的巴沙木板材与目前风电叶片普遍应用的环氧灌注树脂,对不同含水率的巴沙木本体与壳体形式的压缩与面外剪切性能的影响进行了研究与分析。实验结果表明:0%、2.5%、5%、7.5%、10%的含水率对本体、壳体形式的压缩性能均有影响,由于水分会影响木材间纤维结合能力,含水率越低巴沙木压缩与剪切性能越好,为叶片生产中巴沙木含水率的控制提供了数据支撑,同时评估了过高含水率巴沙木对树脂灌注的影响,为工厂的生产提供指导。Balsa,also known as light wood,is one of the commonly used materials for manufacturing wind turbine blades.At present,the moisture content of Balsa used for wind turbine blades is usually controlled below 12%,and too high moisture content will cause defects in blade production.In order to study the influence of different moisture content,this paper selects the commercially available Balsa plate and the epoxy resin widely used in wind turbine blades,and studies and analyzes the influence of different moisture content on the compression and out of plane shear properties of Balsa body and shell.The experimental results show that the moisture content of 0%,2.5%,5%,7.5% and 10% has an impact on the compression performance of the body and shell.Because the moisture will affect the fiber bonding ability between wood,the lower the moisture content,the better the compression and shear performance of Balsa,which provides data support for the control of Balsa moisture content in leaf production.At the same time,the impact of high moisture content of Balsa on resin pouring is evaluated,which has guiding significance for the production of the factory.
