The primary mode of failure in structures composed of coated fabrics is often by means of propagation of a tear or crack. Fracture models used for metal structures have generally not worked well for these materials. This investigation pro vides an evaluation of several fracture models developed for continuous fiber com posites to predict failure in coated fabrics. The inherent flaw model, the point stress model, and the modified singularity model were all found to correlate well with ex perimental data from strength testing of coated fabrics.
