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 two of these panels - both 0.0625 m2, one with a mass of 38 g and one with a mass of 25 g - to develop validated computer models which can be used to determine the effects of changing manufacturing parameters and scalability. Static bending tests showed linear full-panel behavior over a range of applied loads for two different polyimide film thicknesses. These data were replicated by simple, coarsely-meshed shell element finite element models that are substantially smaller than three-dimensional models that faithfully represent the detailed internal geometry of the stiffened panels.
