本文以丙纶(PP)长丝、亚麻为原料,通过包缠方式将PP长丝包覆在亚麻表面以形成PP/亚麻包缠纱;分别以PP/亚麻包缠纱为经纬纱,在全自动剑杆织样机上制织三种典型的2.5维(浅交弯联、浅交直联、深角联)机织物,并将该机织物通过热压的方式制成汽车内饰用2.5维机织复合材料,研究不同组织结构对复合材料拉伸性能的影响。结果表明,2.5维机织物的经向拉伸性能表现为深角联>浅交直联>浅交弯联,纬向拉伸性能相差不大;2.5维机织复合材料的拉伸性能表现为浅交直联>浅交弯联>深角联,纬向拉伸性能相差不大。
In this paper, polypropylene (PP) filaments and flax are taken as raw materials, PP filaments are wrapped on flax surface by wrapping to form PP / flax wrapping yarn. The PP / flax wrapping yarn is warp and weft yarn, Three kinds of typical 2.5-dimensional (shallow handicraft couple, shallow hand straight couple, deep corner joint) woven fabrics are woven on a rapier prototype, and the woven fabric is made into a car interior by hot pressing with 2.5-dimensional woven Composite materials, the impact of different organizational structures on the tensile properties of composite materials. The results show that the warp tensile properties of 2.5-dimensional woven fabric are as follows: deep-angle joint> shallow-cross-straight joint> shallow cross-bend joint; the tensile properties of the 2.5-dimensional woven composite show shallow Cross-straight> shallow handicraft couplet> deep corner joint, latitudinal stretching performance is not big difference.
