摘要:

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作为经纱、纬纱和针织纱编织织物,以其作为增强体,采用VARTM工艺制作玄武岩纤维/乙烯复合材料。为提供这种新型织物增强复合材料的应用依据,测试了复合材料的横向、纵向和斜向拉伸性能,并对各个方向的拉伸应力与应变特征曲线及其拉伸断裂形态进行分析,对比了复合材料中经纱和纬纱强力。研究结果表明:这种复合材料具有较好的轴向拉伸性能,横向和纵向的拉伸性能均优于斜向,其拉伸断裂均为脆性断裂;纬纱的强力高于经纱。

Abstract:

According to the structural features of co-woven-knitted fabric (CWK), high tenacity and high modulus basalt fiber filaments with different linear density were used as warp, weft and stitch yarn to produce the CWK fabric, which was used as reinforcement in making basalt filament/ethylene composite by VARTM process. For exploring the application fields of the CWK reinforced composites, the tensile of cross, longitudinal, and diagonal direction were tested. The mechanical properties of the composites were investigated by analyzing the stress-strain curves and breaking elongation. The strength comparison was made between the warp and weft of the composites. The results revealed that the tensile strength in the axial direction was relatively higher, and the tensile strength in weft and warp directions was better than that in diagonal direction. Brittle elongation breaking was observed, and the strength of the weft yarn is higher than that of warp yarn.
