Book Synopsis Properties of Graphite Fiber Composites at Cryogenic Temperatures by : Robert A. Simon
Download or read book Properties of Graphite Fiber Composites at Cryogenic Temperatures written by Robert A. Simon and published by . This book was released on 1970 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of mechanical properties of several graphite fibers and resins as composite strands, bars, and NOL rings showed that composite moduli increased by 0 to 30%. Bending fatigue at 50% breaking stress and 100 cycles deteriorated rings less when cold than when at room temperature. Thermal contraction tests of composite showed the graphite fibers to have a slight negative coefficient. Combined with resins in composites, the resin matrix would experience up to 1.5% strain when cold due to its thermal contraction. The design, fabrication, and testing of graphite filament wound pressure vessels are reported.

Book Synopsis Effects of Thermal and Environmental Exposure on the Mechanical Properties of Graphite/polyimide Composites by : M. P. Hanson
Download or read book Effects of Thermal and Environmental Exposure on the Mechanical Properties of Graphite/polyimide Composites written by M. P. Hanson and published by . This book was released on 1971 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composites were exposed in circulating and static air environments up to 589 K for a maximum of 1000 hours. Composites of HT-S, HM-S, Thornel 50S, and Fortafil 5-Y fiber and a new addition type polyimide resin were laminated in a matched-die mold. Flexural strengths, flexural modulus, and interlaminar shear strengths were determined at 297, 533, and 598 K after various durations of exposure. Composite and fiber weight loss characteristics were determined by isothermal gravimetric analysis in air. Properties of composites exposed and tested at the environment temperatures were compared with those determined under short-term exposure. A new short beam interlaminar shear fixture is described. Environmental effects of long-term ambient temperature exposure on the elevated temperature mechanical properties of graphite/polyimide composites are presented.
Download or read book Fiber Fracture written by M. Elices and published by Elsevier. This book was released on 2002-11-15 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for this book came out of the EURESCO Conference on High Performance Fibers: Euroconference on Fiber Fracture in 2000. Many of the books that are currently available look at different aspects of fiber processing, properties, or applications, but none are focussed on the fracture behaviour of fibers. This book presents the mechancisms and models of fiber fracture currently available for both natural and synthetic fibers, and it is expected that increasingly there will be cross fertilization between the fields, opening new frontiers in academic research and more competitive products for industry. It covers the following areas of fiber fracture: ceramic fibers; glass fibers; carbon filters; metallic fibers and thin wires; polymeric fibers; and carbon nanotubes.
Book Synopsis Cryogenic Temperature Effects on the Mechanical Properties of Carbon, Aramid, and PBO Fibers by : William Chad Hastings
Download or read book Cryogenic Temperature Effects on the Mechanical Properties of Carbon, Aramid, and PBO Fibers written by William Chad Hastings and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the effects of cryogenic temperatures on the mechanical properties of carbon, aramid, and poly(p-phenylene-2, 6-benzobisoxazole) (PBO) fibers. Although the mechanical properties are documented for these fibers at ambient and elevated temperatures, there is an absence of data in the open literature for how these fibers behave at very low temperatures. To evaluate the mechanical properties, the ASTM standard method for testing at ambient temperature was used as a baseline. The low temperature tests were conducted inside a double walled cryogenic chamber to evaluate the fiber performance at 100K. Fiber properties at low temperatures displayed differences from room temperature properties in the form of increased ultimate tensile strength (UTS), decreased in elongation to failure, and increased Young's Modulus. The change in properties due to the effect of temperature was more pronounced in fibers with a higher degree of crystallinity.

Book Synopsis Nonmetallic Materials and Composites at Low Temperatures by : A. F. Clark
Download or read book Nonmetallic Materials and Composites at Low Temperatures written by A. F. Clark and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryogenics is an emerging technology filled with promises. Many cryogenic systems demand the use of nonmetallics and composites for adequate or increased performance. Thermal and electrical insulations, potting for superconducting magnets' mechanical sta bility, and composite structures appear to be some of the most significant applications. Research on nonmetallics at cryogenic temperatures has not progressed to the degree of research on metals. Nor can room temperature research be extrapolated to low tempera tures; most polymers undergo a phase transformation to the glassy state below room temperature. Research by producers, for the most part, has not been prac tical, because, except for LNG applications, the market for large material sales is not imminent. There are, however, many government stimulated developmental programs. Research on nonmetallics thus is dictated by development project needs, which require studies orien ted toward prototype hardware and specific objectives. As a result, research continuity suffers. Under these conditions, periodic topical conferences on this subject are needed. Industry and uni versity studies must be encouraged. Designers and project research material specialists need to exchange experiences and data. Low temperature-oriented research groups, such as the National Bureau of Standards and the Institute for Technical Physics - Karlsruhe, must contribute by assisting with fundamentals, interpreting proj ect data, and contributing to project programs through their materials research.

Book Synopsis Applications of Cryogenic Technology by : J. Patrick Kelley
Download or read book Applications of Cryogenic Technology written by J. Patrick Kelley and published by Springer Science & Business Media. This book was released on 1991-06-30 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of Cryogenic Technology, Vol. 10, is the proceedings from the portion of the conference CRYO-90 sponsored by the Cryogenic Society of America (CSA). CRYO-90, held on the campus of the State University of New York, Binghamton, New York, was an unusual interdisciplinary event, drawing from the life sciences as well as the physical science and engineering areas of the low temperature community. Co-sponsoring CRYO-90 with CSA were the Society for Cryobiology and the Symposium on Invertebrate and Plant Cold Hardiness. These latter two organizations brought an exciting developing field to the conference, a field whose exploration will lead to the betterment of all mankind through improved cryosurgical and organ preservation techniques in addition to improved agricultural and herd yields under extreme conditions. Specific goals of the cryobiological community are cryopreservation, the arrest and recovery of living processes of cells, tissues and organs; and cryosurgery - the local cryodestruction of diseased cells while preserving the healthy surrounding tissue. These goals present great technological challenges. The technological requirements of the cryobiologist include the ability to cool tissues 6 at rates of 10 degrees per second (vitrification), to thaw frozen tissue without damaging the delicate cells, to freeze dry tissue using molecular distillation (vacuum) drying, to supercool cell structures below O°C without freezing, and to successfully store the preserved tissues and organs for any required length of time.

Download or read book Advances in Cryogenic Engineering Materials written by A. F. Clark and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Third International Cryogenic Materials Conference (ICMC) was held in Madison, Wisconsin, in conjunction with the Cryogenic Engineering Conference (CEC) in August 1979. The University of Wisconsin hosted the two conferences in an excellent manner and deserves special recognition and praise. The synergism produced by conducting the two conferences simultaneously continues to be strong. Materials remain a demanding challenge and, in some cases, an obstacle to effective application of cryogenic technology. The association of materials specialists and cryogenic engineers every other year centers their attention on the most needed areas of research. The present ICMC Board met during the conference and elected two new members, E. W. Collings (U. S.) and D. Evans (England). The board voted to conduct two smaller, special-topic conferences in 1980. These are Filamentary A15 Superconductors, which was held at Brookhaven National Laboratories, Upton, New York in May 1980, and Fundamentals of Nonmetallics and Composites at Low Temperatures, held in Geneva, Switzerland in August 1980. The 1981 CEC/ICMC will be held August 10 through 14 in San Diego, California.
