In the molding manufacturing process of the composite material, winding molding manufacturing is the most common molding manufacturing method, and the composite material winding molding manufacturing method is to wind a composite material strip on the surface of a mold to form a preform, and then to solidify and release the mold.
The composite material part to be wound is generally a cylindrical or conical rotary part. The cylindrical composite material part is mostly formed and manufactured by straight winding, and the conical part is mostly formed and manufactured by oblique winding. The straight winding and the oblique winding are two types which are more applied in the manufacturing process of winding and forming the composite material.
