Available in PDF, EPUB and Kindle. Book excerpt: This final report summarizes the research results on space environmental effects including vacuum, temperature, and radiation on the coefficient of thermal expansion (CTE), stiffness, creep, and material damping in graphite/epoxy and Kevlar/epoxy composite laminates, obtained over the period 1 November 1981 to 31 October 1982 under AFOSR-78-3694 funding. This submission is intended to supplement the previous three annual reports and thus should be read in context with those documents. The main accomplishments in this 12 month period have been in the study of UV and electron radiation effects on composites in a thermo-vacuum environment, and the development and experimental validation of viscoelastic and laminate damping models for composites. In hard vacuum, matrix stiffness increases over a wide temperature range, matrix creep compliance and material damping decrease, and CTE changes depending on laminate configuration. Combined UV radiation in hard vacuum along with some Beta-radiation testing produced only minor variation in matrix stiffness, creep compliance, and CTE iwth exposures up to 300 equivalent solar days. Thermal-vacuum cycling resulted in matrix stiffness and tensile strength reduction, and CTE drift. Laminate models used were quite accurate in predicting CTE, damping, creep, and strength of arbitrary laminate configurations based on material property data obtained under different environmental conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Advanced polymer matrix composites (PMC) have many advantages such as light weight and high specific strength that make them useful for many aerospace applications. Enormous uncertainty exists, however, in predicting long-term changes in properties of PMCs under extreme environmental conditions, which has limited their use. To help address this issue, the Department of Defense requested a study from the NRC to identify the barriers and limitations to the use of PMCs in extreme environments. The study was to focus on issues surrounding methodologies for predicting long-term performance. This report provides a review of the challenges facing application of PMCs in extreme environments, the current understanding of PMC properties and behavior, an analysis of the importance of data in developing effective models, and recommendations for improving long-term predictive methodologies.

Available in PDF, EPUB and Kindle. Book excerpt: The National Aeronautics and Space Administration (NASA) and the Strategic Defense Initiative Organization (SDIO) cosponsored a workshop on Space Environmental Effects on Materials at the NASA Langley Research Center from June 28 to July 1, 1988. The joint workshop was designed to inform participants of the present state of knowledge regarding space environmental effects on materials and to identify knowledge gaps that prevent informed decisions on the best use of advanced materials in space for long-duration NASA and SDIO missions. Establishing priorities for future ground-based and space-based materials research was a major goal of the workshop. The end product of the workshop was an assessment of the current state-of-the-art in space environmental effects on materials in order to develop a national plan for spaceflight experiments. The workshop was intended for participation by expert applied researchers, systems technologists, and program managers for spacecraft systems.

Available in PDF, EPUB and Kindle. Book excerpt: Nothing stays the same for ever. The environmental degradation and corrosion of materials is inevitable and affects most aspects of life. In industrial settings, this inescapable fact has very significant financial, safety and environmental implications. The Handbook of Environmental Degradation of Materials explains how to measure, analyse, and control environmental degradation for a wide range of industrial materials including metals, polymers, ceramics, concrete, wood and textiles exposed to environmental factors such as weather, seawater, and fire. Divided into sections which deal with analysis, types of degradation, protection and surface engineering respectively, the reader is introduced to the wide variety of environmental effects and what can be done to control them. The expert contributors to this book provide a wealth of insider knowledge and engineering knowhow, complementing their explanations and advice with Case Studies from areas such as pipelines, tankers, packaging and chemical processing equipment ensures that the reader understands the practical measures that can be put in place to save money, lives and the environment. The Handbook's broad scope introduces the reader to the effects of environmental degradation on a wide range of materials, including metals, plastics, concrete,wood and textiles For each type of material, the book describes the kind of degradation that effects it and how best to protect it Case Studies show how organizations from small consulting firms to corporate giants design and manufacture products that are more resistant to environmental effects

This book was released on 2006-03-09 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication presents the proceedings of ICPMSE-6, the sixth international conference on Protection of Materials and Structures from Space Environment, held in Toronto May 1-3, 2002. The ICPMSE series of meetings became an important part of the LEO space community since it was started in 1991. Since then, the meeting has grown steadily, attracting a large number of engineers, researchers, managers, and scientists from industrial companies, scientific institutions and government agencies in Canada, U. S. A. , Asia, and Europe, thus becoming a true international event. This year’s meeting is gaining even stronger importance with the resumption of the ISS and other space projects in LEO, GEO and Deep Space. To reflect on these activities, the topics in the program have been extended to include protection of materials in GEO and Deep Space. The combination of a broad selection of technical and scientific topics addressed by internationally known speakers with the charm of Toronto and the hospitality of the organizers brings participants back year after year. The conference was hosted and organized by Integrity Testing Laboratory Inc. (ITL), and held at the University of Toronto’s Institute for Aerospace Studies (UTIAS). The meeting was sponsored by the Materials and Manufacturing Ontario (MMO) and the CRESTech, two Ontario Centres of Excellence; Air Force Office of Scientific Research (AFOSR/NL); MD Robotics; EMS Technologies; The Integrity Testing Laboratory (ITL); and the UTIAS.

Available in PDF, EPUB and Kindle. Book excerpt: A variety of environmental factors can influence the performance of advanced polymers and composites. In particular, exposure to a combination of moisture and elevated temperature can significantly alter properties. The extent of chemical and physical changes is a function of exposure time and the temperature and humidity of the environment. This work discusses the effects of chemical and physical aging of AFR700B, a high-temperature addition polyimide resin. Neat resin samples were isothermally aged for 500 and 1000 hours at 250 deg C in dry air, humid air, and dry nitrogen. Changes in the dynamic mechanical properties and weight of the resin samples after these different exposures are discussed. An accelerated aging process was developed to facilitate the study of hydrolytic degradation. The effect of degradation on the Tg, weight, and mechanical behavior is discussed. The use of a silicon-nitride moisture barrier proved ineffective.
