Preparation and Physical Properties Evaluation of glass/wood Pulp Fibers wet-laid Felts

ABSTRACT

Mechanical properties of pure glass fiber wet-laid felts with no adhesives are relatively poor and limit the using. The aim of this study is to analyze the hybrid effects of glass/wood pulp wet-laid felt (GWFF) via papermaking technology. The influence of wood pulp fiber weight ratios on the physical properties of GWFFs is studied. The results show that GWFFs can obtain excellent uniformity when wood pulp fiber weight ratios are less than 50%. GWFFs with 20% wood pulp fiber weight ratios exhibit optimum break elongation, flexural property, and bursting strength. It also finds that tensile strength and Young’s modulus increase with wood pulp fiber weight ratios due to the effect of surface roughness of fibers and hydrogen bonds between fibers.

摘要

无粘合剂的纯玻璃纤维湿铺毡的力学性能较差, 限制了其使用. 本研究旨在通过造纸技术分析玻璃/木浆湿铺毡 (GWFF) 的混合效应. 研究了木浆纤维重量比对GWFFs物理性能的影响. 结果表明, 当木浆纤维重量比小于50%时, GWFFs可获得良好的均匀性. 木浆纤维重量比为20%的GWFF具有最佳的断裂伸长率、弯曲性能和耐破强度. 由于纤维表面粗糙度和纤维间氢键的影响, 拉伸强度和杨氏模量随木浆纤维重量比的增加而增加.
