Abstract

Stiff, thermal-formed polyimide panels are examples of next generation space structures that address some of the issues of membrane-dominated ultra-lightweight structures while maintaining their low mass and low stowage volume characteristics. The research presented here involved statically characterizing and modeling one of these panels - 0.1875 m² with a mass of 81 g - to develop computer models which can be used to determine the effects of changing manufacturing parameters and scalability. Cantilevered bending tests characterized panel behavior. These data were replicated by simple, coarsely-meshed shell element finite element models that are significantly smaller than previous finite element models of similar structures.
