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.

Book Synopsis Protection of Materials and Structures from Space Environment by : J. Kleiman
Download or read book Protection of Materials and Structures from Space Environment written by J. Kleiman and published by Springer Science & Business Media. 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: 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: It was the 50s and life was simple, until September 25, 1954. That was the night that would be etched in the memory of the citizens of Stanfield, Massachusetts. The Chief of Police described the brutal savagery of the double homicide as "the most atrocious crime in the history of the city." A fourteen-year-old girl, and the four-year-old boy in her care were murdered at the hands of a deranged, depraved killer. A Thread of Evidence places the reader at the scene of the crime, an eye witness to the senseless stabbing of two innocent children. With a piece of crochet thread as their only clue, the entire police department, lead by detectives Steven Logan and Raymond Gage, scour the city in search of a maniacal savage. When all tips and leads have been exhausted, they review all evidence. They come back to the thread. The only real evidence. With tenacity and perseverance of Logan and Gage the killer is apprehended. The reader experiences the twists and turns of the investigation, and ultimately occupies a reserved seat in the Superior Court as the trial proceedings commence. A Thread of Evidence has been written as fiction, but inspired by an actual event. Fifty years later, it remains etched in the minds of all who had lived in the area. The author has researched court records, newspapers, interviewed neighbors, police and has drawn on personal recollections of the crime. The story has been recounted over and over and to this day, it continues to be discussed. A Thread of Evidence is a compelling account of superb detective work, and unprecedented dedication of an entire police department.

Book Synopsis The Effects of Simulated Space Environmental Parameters on Six Commercially Available Composite Materials by : National Aeronautics and Space Adm Nasa
Download or read book The Effects of Simulated Space Environmental Parameters on Six Commercially Available Composite Materials written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2018-10-12 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of simulated space environmental parameters on microdamage induced by the environment in a series of commercially available graphite-fiber-reinforced composite materials were determined. Composites with both thermoset and thermoplastic resin systems were studied. Low-Earth-Orbit (LEO) exposures were simulated by thermal cycling; geosynchronous-orbit (GEO) exposures were simulated by electron irradiation plus thermal cycling. The thermal cycling temperature range was -250 F to either 200 F or 150 F. The upper limits of the thermal cycles were different to ensure that an individual composite material was not cycled above its glass transition temperature. Material response was characterized through assessment of the induced microcracking and its influence on mechanical property changes at both room temperature and -250 F. Microdamage was induced in both thermoset and thermoplastic advanced composite materials exposed to the simulated LEO environment. However, a 350 F cure single-phase toughened epoxy composite was not damaged during exposure to the LEO environment. The simuated GEO environment produced microdamage in all materials tested.
