This book was released on 1965 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 strength/weight 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.

This book was released on 1965 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The summation of the progress reported in this, the first of twelve monthly reports, concerns resin research and development. Material development has included the defining and establishing of test procedures to determine resin characteristics. Equipment and methods have been developed to (1) evaluate flexural strength and flexural modulus, (2) evaluate the rate of cure, and (3) determine resin shrinkage during cure. Solar collector development engineering has not progressed beyond the planning stage since a subcontract program planned for this phase of the work has not yet been initiated. Resin development has been recorded in (1) isocyanate terminated prepolymers and (2) acetoxy silane prepolymers.

This book was released on 1966 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the search for optimum materials to be used in an expandable sandwich concept of fabricating space structures, a gelatin rigidizing resin system was improved and adapted for use. It was demonstrated that this system would be desirable for use with fabric materials. The resin system is easily applied, has high strength to weight ratio, and is resistant to a space environment. The other materials finally selected for use are completely compatible and equally resistant to a space environment. The final items of the development program were lightweight, self-rigidizing, 10-foot diameter solar energy concentrators; and 4-foot diameter cylinders, 8-foot long. Space systems considerations were an integral part of this study, with particular emphasis on much larger structures requirements.
