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.

This book was released on 1965 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the search for optimum materials for use in an expandable sandwich concept of fabricating space structures, a gelatin rigidizing resin system was improved and adapted for use to rigidize space structures. It was demonstrated that a protein system is a desirable system for use with fabric materials. The system provided an easily applied, high strength, space environment resistant material which offers good promise for use in actual space systems. The final items of the development program were lightweight, self-rigidizing 2-1/2 ft diameter solar energy concentrators and 3-1/2 ft diameter by 4-ft high cylindrical space shelter models. These structures were vacuum cured by a plasticizer boil-off process of a gelatin resin system.

Download or read book AEROSPACE EXPANDABLE STRUCTURES AND MAINTENANCE SUPPORT DEVICES VOLUME 1 EXPANDABLE SELF RIGIDIZING SOLAR ENERGY CONCENTRATORS AND AEROSPACE SHELTERS FROM HONEYCOMB TYPE FABRIC written by and published by . 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.

Book excerpt: This book collects state-of-the-art research and technology for design, analysis, construction and maintenance of textile and inflatable structures. Textile composites and inflatable structures have become increasingly popular for a variety of applications in OCo among many other fieldsaOCo civil engineering, architecture and aerospace engineering. Typical examples include membrane roofs and covers, sails, inflatable buildings and pavilions, airships, inflatable furniture, airspace structures etc. The book contains 18 invited contributions written by distinguished authors who participated in the International Conference on Textile Composites and Inflated Structures held in Barcelona from June 30th to July 2nd, 2003. The meeting was one of the Thematic Conferences of the European Community on Computational Methods in Applied Sciences (ECCOMAS). The different chapters discuss recent progress and future research directions in membrane and inflatable structures built with new textile composite materials. Approximately half of the book focuses on describing innovative numerical methods for structural analysis of such structures, such as new nonlinear membrane and shell finite elements. The rest of the chapters present advances in design, construction and maintenance procedures."
