Research on Tension Control Technology for Discontinous Tape Winding

The discontinous tape winding is one kind of tape winding, which is widely used in the molding of composite materials. Particularly, it has obvious advantage in the winding of large tension ratio. Aimed at the winding of discontinuous tape and based on the analysis of the molding of composite materials and the possible technical difficulties, this article gives a comparatively deep research on the control method and interaction mechanism of tension, tension ratio, automatic lap and rectification which influence the quality of the winded products. Moreover, the feasible mechanical set and control scheme are designed. According to the application verification, the scheme not only automates the discontinous tape winding process, but also ensures the quality of the winded products, and solves the key problems of control technology in the molding process of discontinous tape.
