Embodiment 1
[0041] Design a four-gradient two-coil-changing-coil biaxially multi-layered weft knitted fabric (see figure 1 and Figure 8 ).
[0042] The binding yarn is 11.2tex glass fiber × 8 strands, the weft-lining yarn and the warp-lining yarn are both 6K T300 carbon fiber, the warp-lining layer is 1 layer, the warp-lining yarn is 4, the warp-lining density is 12 threads / inch, and the weft-lining yarn The number of layers is 2 layers, the density of weft-inserted yarns is 12 / inch, and the fabric width is 34mm. Among them, the width of the first gradient area with interlaced warp yarns is 8.5mm, and the second gradient, third gradient and fourth gradient without interlaced warp yarns The area widths are all 8.5 mm, and the sum of the area widths from the second gradient to the fourth gradient area of the unlined warp yarn is 25.5 mm.

Embodiment 2
[0048] Design a four-gradient three-coil variable-coil biaxial multi-layer weft knitted fabric (see figure 2 and Figure 8 ).
[0049] The binding yarn is 11.2tex glass fiber × 8 strands, the weft-lining yarn and the warp-lining yarn are both 6K T300 carbon fiber, the warp-lining layer is 1 layer, the warp-lining yarn number is 6, the warp-lining yarn density is 12 threads / inch, and the weft-lining yarn The number of layers is 2 layers, the density of inserted weft yarns is 12 / inch, and the fabric width is 50.8mm. Among them, the width of the first gradient area with lined warp yarns is 12.7mm, and the second gradient, the third gradient and the fourth gradient without lined warp yarns The widths of the gradient regions are all 12.7 mm, and the sum of the widths of the second gradient to the fourth gradient regions of the unlined warp yarn is 38.1 mm.

Embodiment 3
[0055] Design a four-gradient four-coil-changing-coil biaxial multi-layer weft knitted fabric (see image 3 and Figure 8 ).
[0056] The binding yarn is 11.2tex glass fiber × 8 strands, the weft-lining yarn and the warp-lining yarn are both 6K T300 carbon fiber, the warp-lining layer is 1 layer, the warp-lining yarn number is 8, the warp-lining yarn density is 12 threads / inch, and the weft-lining yarn The number of layers is 2 layers, the density of inserted weft yarns is 12 / inch, and the fabric width is 67.6mm. Among them, the width of the first gradient area with lined warp yarns is 16.9mm, and the second gradient, the third gradient and the fourth gradient without lined warp yarns The widths of the gradient regions are all 16.9 mm, and the sum of the widths of the second gradient to the fourth gradient regions of the unlined warp yarn is 50.7 mm.
