Embodiment 1
[0029] Adopt the trapezoidal body component (referring to of the inventive method weaving) Image 6 ). The cross-sectional size of its large end is 100mm×1.5mm (width×thickness), the trapezoid height is 100mm, the warp yarn density is 10 yarns / cm, the weft yarn density is 8 yarns / cm, the warp and weft yarns are carbon fiber T300-3K, and the reed used is 10 teeth / cm. According to the size requirements and density of the workpiece, the number of warp yarns required is 500, and the length of the warp yarns must be at least greater than 100mm.
[0030] Warp yarn 5 is passed through reed 4 according to the requirement of warp density, and is suspended on the yarn hanging point 9 on the machine chassis 7 . The up and down reciprocating motion of the machine chassis 7 drives the warp yarn 5 to reciprocate up and down, and 6 or 4 channels are formed between the warp yarns 5 during the up and down reciprocating process. At this time, the weft yarn 3 is passed through the channels in ...
