摘　　要： 经纬纱和针织纱分别使用玻璃纤维和高强涤纶编织新型机织针织复合织物作为增强体,采用真空辅助树脂传递模塑(VARTM)工艺制作聚乙烯树脂复合材料.对该新型复合材料的横向、纵向和斜向拉伸性能进行测试,并对拉伸应力-应变特征曲线及其拉伸断裂形态进行分析.研究表明:该类复合材料具有较好的拉伸性能,横向和纵向的拉伸性能均优于斜向,其拉伸断裂都为脆性断裂.研究结果为该新型织物增强复合材料的应用提供了必要的基础. A novel co-woven-knitted fabric was produced using glass filaments as warp and weft inserted yarns and high tenacity polyester as stitch yarn and used for reinforcing the co-woven-knitted composites by Vacuum Assisted Resin Transfer Molding（VARTM）process.Tensile tests were carried out in the course,wale and bias directions.The mechanical properties of the composites were investigated by analyzing the stress-strain curves and the damage modes.The results revealed that the tensile strength and the elastic modulus in the course and wale directions were all better than in the bias direction,and the damage modes were the brittle fracture.These provided a basis for the application of the co-woven-knitted reinforced composites.
