摘要(Abstract)：

为探讨芳纶纬编增强体复合材料的力学性能,以对位芳纶为原料,采用LiCl/无水乙醇溶液对芳纶表面进行改性处理,设计并编织1+1满针罗纹和罗纹空气层2种组织织物增强体,以E-51环氧树脂为基体,应用手糊成型技术制备芳纶纬编增强体平板复合材料。采用YG026D型电子织物强力机对制备的芳纶纬编增强体复合平板材料的经纬向拉伸、弯曲、压缩以及层间剪切性能进行测定。结果显示:经LiCl/无水乙醇络合溶液处理的芳纶纬编增强体复合材料的各项力学性能均有所提高,且经向的各项力学性能优于纬向。在拉伸、弯曲性能方面,罗纹空气层芳纶纬编增强体平板复合材料优于1+1满针罗纹芳纶纬编增强体复合材料。
To discuss the mechanical properties of aramid weft-knitted reinforced composites, using aramid fiber as raw materials, surface modification treatment of aramid fiber was done with LiCl/anhydrous ethanol.Two kinds of fabric reinforcements with 1+1 full-needle rib and rib air layer were designed and knitted. Using E-51 epoxy resin as the matrix, the aramid knitted reinforced flat plate composites were prepared by hand paste molding technology. The tensile, bending and compression properties of aramid weft-knitted reinforced composite plate were measured by YG026 D electronic fabric strength machine. The results show that the mechanical properties of aramid weft-knitted reinforced composites treated with LiCl/anhydrous ethanol complexing solution have been improved, and the mechanical properties of longitude are better than that of latitude. The mechanical properties of 1+1 full-needle ribbed knitted reinforced composites are better than rib air layer knitted reinforced plate composite such as tension, bending strength.
