In this paper, a polyester double-tape seam is studied both experimentally and numerically. In the numerical analysis, the seam components are described with layered models containing fabric composite layers. The in-plane and out-of-plane elastic constants of the fabric composite layers are derived using a crimp model and a stacked model respectively. An existing finite element code, ANSYS 5.7, is used to perform two-dimensional stress analysis of the seam under tension. Numerical results identified the stress concentration causing strength loss in the seam. Finally, two structural modifications are proposed to improve the seam strength. The modifications are evaluated by both simulations and tests.
