Description/Abstract

One of the most significant drivers in satellite design is the minimization of mass to reduce the large costs involved in the launch.With technological advances across many fields, it is now widely known that very low-mass satellites can perform a wide variety of missions. However, there is a need for small, efficient, area deployment devices.

One possible structural solution for such devices is tape springs. Previous work on tape spring hinges has focused on two-dimensional folds; however, applications exist that incorporate three-dimensional tape spring folds. The properties of three-dimensional tape spring folds are experimentally investigated using a specially designed test
rig. The rig is first used to produce comparative two-dimensional data before being used to analyze more complex
three-dimensional folds.
