Book excerpt: The goals of this experimental program were to optimize the effectiveness of an icephobic coating for use on several Space Shuttle surfaces, to evaluate the effects of adding an ultraviolet light absorber (UVA) on coating performance, and to assess the consistency and durability of the basic coating and its modifications. The double lap shear test was used to quantify ice adhesion performance at a constant temperature of 112 C (170 F). The experiments used ice that was grown as strong and consistently as possible before being subjected to the extreme temperature decrease. Standardized coating application with a foam brush provided consistent and reproducible surface coverage. The program included 20 tests subdivided in two phases. Phase 1 focused on determining an optimal coating of Rain-X and varying weight fractions of PTFE powders MP-55 and UF-8TA. Ice adhesion to the UF-8TA coatings was similar to that of the uncoated controls. Conversely, the MP-55 coatings produced large reductions in ice adhesion. Through three cycles of phase 1 testing the M4 coating, a mixture of 60% Rain-X with 40% MP- 55, was the best and most consistent by a wide margin. As a result, M4 was the basis of all phase 2 mixes. Phase 2 tests sought to verify the effectiveness and durability of the optimal coating for several surfaces on the shuttle and to quantify any changes in effectiveness resulting from the addition of UVA to the coating. The ice adhesion to coated coupons with Koropon, Kapton tape, Kapton film, and Fire-X (fire-retardant paint) surfaces was a small fraction of the adhesion to corresponding uncoated coupons. Rain-X solvent loss during prolonged coating preparation caused a greater increase in ice adhesion than that of adding the UVA. A rapid mixing procedure was developed to minimize this problem. The M4 coating showed outstanding performance and durability through five cycles of ice growth and adhesive failure.

Book excerpt: The brackets that secure the liquid oxygen feed line to the external tank are known locations of frost and ice growth during the period following fuel loading. This experiment quantified the reduced adhesion when ice phobic coating were applied to test coupons simulating the bracket surface. Double lap shear testing of coated and uncoated coupons provided robust test specimens and consistent load response patterns with exceptional resolution. For these tests ice was grown as strong and consistently as possible, subject to temperature decreases comparable to those of the prototype bracket, and tested at a controlled temperature of -112 degrees C. The tests evolved in three phases, with uncoated controls included in each group of tested samples. The first phase of testing evaluated a wide range of coatings, and showed that Rain-X mixed with MP-55 powdered Teflon (RXM) was outstanding coating to reduce ice adhesion to Koropon coated aluminum.

Available in PDF, EPUB and Kindle. Book excerpt: NASA commissioned the Columbia Accident Investigation Board (CAIB) to conduct a thorough review of both the technical and the organizational causes of the loss of the Space Shuttle Columbia and her crew on February 1, 2003. The accident investigation that followed determined that a large piece of insulating foam from Columbia's external tank (ET) had come off during ascent and struck the leading edge of the left wing, causing critical damage. The damage was undetected during the mission. The Columbia accident was not survivable. After the Columbia Accident Investigation Board (CAIB) investigation regarding the cause of the accident was completed, further consideration produced the question of whether there were lessons to be learned about how to improve crew survival in the future. This investigation was performed with the belief that a comprehensive, respectful investigation could provide knowledge that can protect future crews in the worldwide community of human space flight. Additionally, in the course of the investigation, several areas of research were identified that could improve our understanding of both nominal space flight and future spacecraft accidents. This report is the first comprehensive, publicly available accident investigation report addressing crew survival for a human spacecraft mishap, and it provides key information for future crew survival investigations. The results of this investigation are intended to add meaning to the sacrifice of the crew's lives by making space flight safer for all future generations.

Available in PDF, EPUB and Kindle. Book excerpt: Over the concluding decades of the twentieth century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, gas stations and diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior’s National Park Service and first published in 1995. Now, this invaluable guide is being reissued—with a new preface by the book’s original editor. With more than 250 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminum, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume. The book is intended for a wide range of conservation professionals including architects, engineers, conservators, and material scientists engaged in the conservation of modern buildings, as well as scholars in related disciplines.

This book was released on 2007-05-08 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the twentieth century, engineers and technologists would have recognized the importance of adhesion in two main aspects: First, in the display of friction between surfaces — at the time a topic of growing importance to engineers; the second in crafts requiring the joining of materials — principally wood—to form engineering structures. While physical scientists would have admitted the adhesive properties of glues, gels, and certain pastes, they regarded them as materials of uncertain formulation, too impure to be amenable to precise experiment. Biological scientists were aware also of adhesive phenomena, but the science was supported by documentation rather than understanding. By the end of the century, adhesion and adhesives were playing a crucial and deliberate role in the formulation of materials, in the design and manufacture of engineering structures without weakening rivets or pins, and in the use of thin sections and intricate shapes. Miniaturization down to the micro- and now to the nano-level of mechanical, electrical, electronic, and optical devices relied heavily on the understanding and the technology of adhesion. For most of the century, physical scientists were aware that the states of matter, whether gas, liquid, or solid, were determined by the competition between thermal energy and int- molecular binding forces. Then the solid state had to be differentiated into crystals, amorphous glasses, metals, etc. , so the importance of the molecular attractions in determining stiffness and strength became clearer.
