Research on control technology for discontinuous tape winding of composite materials

To achieve the technological requirement of large tension ratio for composites winding, discontinuous tape winding was proposed. Based on the research of the molding process and the possible technical difficulties, the control method and the interaction mechanism of tension, tension ratio, automatic lap and rectification were researched, which affected the quality of the requirements of wound products. On the basis of the requirements of winding process requirements, the mechanical device and the control scheme were designed. To verify the rationality of the method, the technological experiments were conducted on the discontinuous tape winding machine. Meanwhile, a comparative analysis of wound products performance was done. The application verifed that variable tension control methods made winding process and lapping process have a different tension, which ensurs a constant tension ratio in the whole winding process. In addition, it did not cause the joint to disconnect again. Therefore, the automation of discontinuous tape winding was realized.
