FIBERGLASS PIPELINE CONTINUOUS FILAMENT WINDING AUTOMATION

– The fiberglass composite materials in many ways solve the problems of operation and maintenance of pipelines in various industries and municipal services. Continuous filament winding is a progressive production method with a high degree of automation. It is necessary to take into account the complex influence of the technological parameters of the used winding method when designing the product structure. The actual problem of creating specialized equipment with continuous axial movement of the wound product is considered. Continuous winding ensures a constant product structure along its entire length. A study of a model for the formation of the structure of a fiber-reinforced pipe during continuous oblique-layer longitudinal-transverse winding is presented. Several types of devices providing the ability to perform continuous filament winding automation have been studied. Mathematical equations for the control parameters of these devices depending on the technological parameters of the winding process are obtained. The possibility of forming a pipe wall thickening in given areas while maintaining the reinforcement structure is shown. Examples of created automated continuous pipe winding equipment are given. A two-level CNC system with coupled control is used to control the equipment. The proposed solutions ensure stable reproduction of the reinforcement structure in modern pipe production conditions.
