采用涤纶长丝和超高分子量聚乙烯(UHM-WPE)纤维编织斜纹布,并与木材复合实现增强的效果,研究了斜纹布与木材复合结构的胶合性能,探讨了UHMWPE在木质材料领域应用的可行性。从斜纹布铺装宽度比设计入手,研究了该复合结构的胶合性能,并对其相关机理进行分析。结果表明,由于木材自身尤其是针叶树材剪切强度(ILSS)较低,PUR 木材层压胶可用做斜纹布/木材复合的基体树脂；在3种 UH-MWPE产品形式中斜纹布的综合性能最优；在拉伸强度允许情况下,采用适当降低斜纹布铺装宽度比的方法可显著提高斜纹布/木材复合结构的 ILSS 值,并从胶层厚度变化入手对影响机理进行了分析。

The twill wove using polyester filament and ultra-high molecular weight polyethylene (UHMWPE) fiber.The bonding performance of composites manufactured with wood lumber and the twill were studied, which was to explore the feasibility of UHMWPE in the field of wooden materials application.The twill widths in the structure of wood composites were designed,and the bonding mechanism was also analyzed.The results show that PUR adhesive could be used as twill/wood composite resin because of the lumber especially softwood lumber had low ILSS.The twill/wood composite had the best comprehensive performance in three kinds of forms of UHMWPE products.The ILSS of twill/wood composite could be significantly improved by decreasing the twill pavement width ratio.At last,the influence bonding mechanism was analyzed at the bondline thickness transition area.
