Abstract:

This project was designed to produce new and improved coated fibrous structure materials for rigidizable expanded structures for future aerospace uses. Woven fiberglas is coated with polymeric compositions designed to retain flexibility until rigidization is required. Two techniques involving removal of part of the coating (normally a plasticizer) are evaluated and found satisfactory for producing a rigid structure. Inflatable structures are used to demonstrate the methods. A third procedure for rigidization is outlined from a theoretical viewpoint only.

The investigation is restricted to continuous-filament glass yarn and coating compounds based on polyvinyl chloride and polyurethane polymers. The effects of yarns, weaves, and coating composition are investigated with respect to their rigidization capability. Criteria used to determine the relative merit of a coated fabric matrix are buckling strength under compression loading and modification of the standard stiffness test for plastics. Relative rates of rigidization are measured for several candidate materials
