This paper presents a design theory and dynamic mechanical characterizations of the composite tape-spring hinge made by two parallel single tape springs.First,the theoretical models of moment-rotation angle on anisotropy tape springs with antisymmetric laminates are proposed.Second,the relationships of moment-rotation angle for tape-spring hinges with different sizes are simulated and analyzed by means of the finite element method (FEM),which is in good agreement with the results from theoretical predictions.Finally,the dynamic vibration analysis for deployable composite tube hinges with different dampings is done during the process of deployment.
