Abstract:

Materials and techniques were improved to advance the concept of expandable,self-rigidizing honeycomb type structures. The strength to weight ratio of structures was markedly improved through the correct utilization of inflatable configurations with a high degree of structural rigidity. A rigidizing resin was developed with an improved strengthweight ratio, a more rapid cure time, and a good shelf life. Solar collectors with reasonably good optical reflectivity and aerospace shelters were fabricated, expanded, and rigidized. Two large sized structures suitable for space application were constructed as end items of this study. Those structures were a 10 foot diameter, 60 degree rim angle solar energy concentrator and a 13 x 15 ft semi-cylindrical aerospace maintenance dock. Both structures utilized a resin impregnated honeycomb type fabric construction and were inflated and rigidized from a packaged configuration. The maintenance dock was successfully designed for 30 psf gravity and 100 mph wind loads. Both structures significantly advanced the concept of expandable, self-rigidizing structures by their size, construction, and performance.
