纤维复合材料已经研究了数十年了。他们有着比传统材料,如钢材,优秀的多的力学性能。然而,由于相对较低的产量,梭织、编织与其3D纤维结构的复合材料被认为较难大量生产。因此,近年来,针织物在复合材料界获得了较高的关注,它的高度可塑性使针织复合材料可以直接生产制造成各种复杂形状的复合材料如管状、圆锥型等,使得材料的浪费可以降到了最低。本文使用了有表面处理和没有表面处理的纬编平针碳纤维制成复合材料。对两种复合材料的经向和纬向分别做了拉伸试验。结果显示:有表面处理的材料具有更好的拉伸性能,尤其是在wale方向上,有表面处理的复合材料比没有表面处理的复合材料的拉伸强度提高75.68%。
Fiber composites have been studied for decades. They have superior mechanical properties than traditional materials such as steel. However, woven fabrics, woven composites with their 3D fiber structures are considered to be more difficult to mass-produce due to the relatively lower yield. In recent years, therefore, knitwear has gained a great deal of attention in the field of composite materials. Its high plasticity enables knit composite materials to be directly manufactured into various complex shapes such as tubular, conical, etc., so that the waste of materials can be Dropped to the lowest In this paper, a composite of plain weft knitted carbon fiber with and without surface treatment was used. Tensile tests were conducted on the warp and weft directions of the two composites respectively. The results show that the surface treated materials have better tensile properties, especially in the wale direction, the tensile strength of the surface treated composites is increased by 75.68% compared with the non-surface treated composites.
