摘　　要：三维织物具有良好的力学性能及层间性能优势,实验中用7200d碳纤维在自制筒子架上预置适当张力制成弹力丝,在8层三维织机上反复实验,确定最佳浅交弯联层数为5层和最佳贯穿正交织物层数为7层。通过多次试验,优化上机工艺参数,设计出5层浅交弯联织物及7层贯穿正交织物的织物组织图及纹板图。采用顺穿法在0.75筘板上按4/4/3和5/6组穿筘。通过改变经纱与芯模之间的夹角改善碳纤维无捻度、耐磨性极差造成织造过程中开口不清的缺点,织造出两种圆筒状三维织物。最终得出结论:5层浅交弯联织物质地柔软,强力低,适合加工成工业管道运输中所使用的管状材料;7层贯穿正交织物表面相对平整,强度高,适合做航空航天中的飞行器外壳的材料。Three-dimensional fabrics have good mechanical properties and interlayer properties.In the experiment,7200d carbon fiber was pre-tensioned on a self-made bobbin frame to make an elastic filament.Repeated experiments were conducted on an 8-layer three-dimensional loom,and the optimal number of shallow bending layers was determined to be 5 layers,while the optimal number of intersecting layers was 7 layers.Through numerous tests and optimization of process parameters,the fabric structure diagram and pattern diagram of the 5-layer shallow cross-bending fabric and the 7-layer intersecting fabric were designed.The reed is threaded in groups of 4/4/3 and 5/6 on the 0.75 reed plate using the sequential threading method.By changing the angle between the warp and the core mold,two kinds of three-dimensional cylindrical fabrics are woven to improve the non-twist of carbon fiber and address the unclear opening caused by poor wear resistance in the weaving process.Finally,it is concluded that the 5-layer shallow cross-bending fabric is soft in texture and low in strength,making it suitable for processing into tubular materials used in industrial pipeline transportation.The 7-layer intersecting fabric surface is relatively flat and high in strength,and it is suitable for aerospace aircraft shell material.
