[0046] The purpose of selecting coated glass fiber is mainly because after coating, the glass fiber can be given color or special functions, thereby meeting customers' demands for different colors and functions.

[0047] In one embodiment, if Figures 1 to 7 As shown, in step S2, the fibers are divided into four groups according to the pre-examination scheme, and the four groups of fibers are arranged in the directions of 0° (longitudinal), 90° (transverse), +45° and -45° (±45° is the cross direction), and then the fiber bundles of 0°, +45°, -45° and 90° are transported to the braiding machine for braiding according to the lamination order and the preset yarn spacing from bottom to top, that is, the 0° fiber is the first layer of fiber 28, the +45° fiber is the second layer of fiber 29, the -45° fiber is the third layer of fiber 30, and the 90° fiber is the fourth layer of fiber 31. The four groups of fibers can select corresponding types of fibers and corresponding colors according to customer needs, such as the four groups of fibers are the same type and the same color, or different types and the same color, or different types and different colors, etc.
