摘　　要：开发具有更高强度和模量的玻璃纤维增强复合材料能更好地满足市场的新需求。文章利用不同的方法将不同规格的玻璃纤维纱线和涤纶丝制备了5种玻璃纤维织物,研究了织物的编织工艺和成型方式等关键制备技术对复合材料的树脂渗透率及复合材料力学性能的影响。研究表明:织物的针脚长度、0°细纱的材质和成型方式等因素影响织物孔隙率、树脂浸透率及复合材料的力学性能。采用二次成型方法和0°玻璃纤维细纱作为绞织纱有利于提高织物的孔隙率,保持规整的织物结构,并有助于提高复合材料的整体力学性能。经优化后的工艺制备得到的玻璃纤维复合材料具有较高的拉伸强度和拉伸模量,预计其将在风电叶片行业中具有广泛的工程应用价值。To develop glass fiber reinforced composites with higher strength and modulus can better meet the new market demand.In this study,5 kinds of glass fiber fabrics were fabricated by using different glass fiber yarns and polyester yarns as raw materials through various knitting technology.The effects of key manufacturing technologies of glass fiber fabric,including knitting technique and forming method,on resin permeability and mechanical properties of composites were investigated.The experimental results show that stitching length of fabric,material type of 0°yarn and forming method could influence fabric porosity,resin permeability and mechanical properties of composites.Adopting two-stage forming method and selecting 0°glass fiber yarn as twisted yarn can increase fabric porosity,maintain the regular fabric structure,and improve the mechanical properties of composites.The glass fiber composite prepared by the optimized process has higher tensile strength and tensile modulus,which is expected to have a wide application in wind power turbine blades.
