There is an effective method of filament winding for the manufacture of hollow composite products (pipes, containers, etc.). Finished products are light, durable and widely used in industry. However, this method has significant drawbacks. The tension of the surface layer and the tension of the inner layers can differ significantly for the products being formed. This effect is also observed when the tension of the wound material is adjusted. Another significant drawback of the technology is the change in the diameter of the cross section of the product in the end zones, where the return movement of the movable trolley with threads (tape) is carried out. As a result of these drawbacks, there are deviations in the winding density and other stress-strain state indicators from the planned values. To eliminate these shortcomings, we propose an original method for controlling the radial increment of the composite winding and its density.
