摘要
为给机织针织复合织物在产业中的应用提供参考,根据新型机织针织复合织物的结构特点,分别选用不同线密度的高强高模玄武岩纤维纺制经纱、纬纱和针织纱编织这种织物,以其作为增强体,采用VARTM工艺制作了玄武岩纤维/乙烯复合材料。并测试该复合材料的横向、纵向和斜向弯曲性能,对各个方向的弯曲载荷挠度特征曲线及其弯曲断裂形态进行分析。结果表明,这种复合材料的横向和纵向弯曲性能均优于斜向,其弯曲破坏都表现为韧性破坏特征,弯曲能量吸收基本相近。
The aim of this study was to give some reference for industrial applications of co-woven-knitted fabrics,thus this paper,based on the structural features of co-woven-knitted fabric（CWK）,selected high tenacity and high modulus basalt continuous filaments with different linear densities as warp and filling as well as stitch yarn to produce CWKs which were used as reinforcement in making basalt filament/ethylene composite by VARTM process.For exploring application fields of the CWK reinforced composites,the cross,longitudinal,and diagonal bending properties of the composites were tested,along with analysis of the load-deflection curves and breaking forms in all directions.The results revealed that the bending properties in the cross and longitudinal directions of the composites were advantageous over those in the diagonal direction.Plastic fracture breaking was observed and bending energy absorbing was similar.
