Available in PDF, EPUB and Kindle. Book excerpt: Select candidate materials arising from earlier investigations were more fully characterized. Investigations of a fluted glass fabric, as a candidate structural component for rigidizable structures, were performed. Two ketone blocked amines were synthesized and characterized. Included in this report are investigations of flexural properties of urethane laminates and shelf stabilities of urethane prepolymers at various temperatures. Also included is the investigation of curing rates of urethane laminates at various temperatures. (Author).

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.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program was to develop a chemical rigidization process that could be activated by an on-command mechanism and be capable of rigidizing expandable solar collectors in a simulated aerospace environment. Six two-foot and three ten-foot diameter solar collectors were fabricated and rigidized in the high vacuum facilities atWright-Patterson AFB, Ohio and were delivered to the Air Force. A fail-safe chemical rigidization system was developed that could be incorporated in a preformed, flexible, polyurethane foam and rigidized by an on-command polymerization initiation. The initiation is accomplished by the introduction of a catalyst which is stored in either microcapsules or an aerosol container. Release is obtained by heat or pressure rupture of the capsules or by spraying the catalyst from the aerosol container. The rigidization reaction, a free-radical polymerization, is a self-propagating reaction, once initiated, in which the rigidization rate can be controlled. Rigidization times for ten foot diameter collectors have been varied from fifteen minutes to two hours. The chemical system, a vinyl-type monomer, has exhibited a sustained shelf-life, under ambient conditions, of approximately eight months without premature curing or adverse effects on the total system. The system has also shown high vacuum stability for periods of three to four hours.

This book was released on 1966 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of the program are: (1) fabrication, space deployment, and rigidification of a large parabolic solar collector; (2) fabrication and space deployment of inflatable, rigidizable space shelter structures. The first 10-foot diameter mirror was completed by addition of the plumbing attachments to the manifold for the rigidization task. However, due to some slight leakage between the inflated sandwich and mirror shell coat, it was decided that this unit will be rigidized in ambient conditions. The 4-foot diameter x 8-foot long cylinder was completed, including impregnation. However, deployment in the vacuum chamber was unsuccessful because the resin had already rigidified.
