guiding and arranging fibers on the yarn roll 1 through a yarn threading plate 3, then enabling the fibers to enter a resin tank 4, and fully soaking the fibers in the resin tank 4 by resin;
s2, winding the fabric, namely,
the fiber soaked with the resin is pulled out from the resin groove 4 and guided by the filament nozzle 6, wherein the resin groove 4 and the filament nozzle 6 travel back and forth along the first track 5 at a set speed, the core mold 7 rotates at a certain rotating speed under the control of the drive control system 9, the fiber soaked with the resin is spirally arranged on the core mold 7 according to the design requirement under the dual action of the rotation of the core mold 7 and the travel of the resin groove 4, and when the fiber travels to the tail end of the core mold 7, the fiber is hooked by a hanging needle on a yarn hanging disc to fix the fiber and return to the back, and finally the fiber is wound on the core mold 7;

When the fiber is soaked in the resin, the comprehensive specific load of the fiber has the value range as follows:
on one hand, when the winding angle is small by 15 degrees, the standard line is approximately positioned on the same horizontal plane because the fiber can be separated from the core mold during the rotation of the core mold, or the fiber is separated from the core mold, and on the other hand, the resin is uniformly distributed on the fiber, and the comprehensive specific load of the fiber is uniformly distributed along the fiber, so that the mechanical state of the fiber in the core mold can be calculated by adopting a parabolic theory.
As shown in fig. 5, an a-xy plane coordinate system is established, in which,
in order to be the winding angle,
the distance between the two binding coils;
is the axial stress at the binding point of A, B,
the horizontal stress at point a. Since the bending moment at any point on the fiber is 0, the force balance equation of the fiber at the points A and 0 can be listed
