Tape springs are being used with increasing frequency in today’s space industry to deploy small satellite aerials and array areas. However, to accurately model the deployment of an appendage mounted with tape spring hinges, it is necessary to accurately model the opening moments produced from the material strains in the tape spring fold. These moments are primarily a function of curvature. This paper uses a photographic method to study the post buckling curvatures at the fold location for both two and three dimensional tape spring folds. The results are finally compared to determine the overall data trends.
