Download or read book Polymer Properties at Room and Cryogenic Temperatures written by Gunther Hartwig and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most descriptions of polymers start at room temperature and end at the melting point. This textbook starts at very low temperatures and ends at room temperature. At low temperatures, may processes and relaxations are frozen which allows singular processes or separate relaxations to be studied. At room temperatures, or at the main glass transitions, many processes overlap and the properties are determined by relaxations. At low temperatures, there are temperature ranges with negligible influences by glass transitions. They can be used for investigating so-called basic properties which arise from principles of solid state physics. The chain structure of polymers, however, requires stringent modifications for establishing solid state physics of polymers. Several processes which are specific of polymers, occur only at low temperatures. There are also technological aspects for considering polymers at low temperatures. More and more applications of polymeric materials in low temperature technology appear. Some examples are thermal and electrical insulations, support elements for cryogenic devices, low-loss materials for high frequency equipments. It is hoped that, in addition to the scientific part, a data collection in the appendix may help to apply polymers more intensively in low temperature technology. The author greatly appreciates the contributions by his coworkers of the Kernforschungszentrum Karlsruhe in measurement and discussion of many data presented in the textbook and its appendix.

Book Synopsis Low-Temperature Properties of Polymers by : I. Perepechko
Download or read book Low-Temperature Properties of Polymers written by I. Perepechko and published by Elsevier. This book was released on 2013-10-22 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-Temperature Properties of Polymers systematizes the available materials on polymers. This book also describes the main trends in the investigation of interrelated properties of polymers, such as thermal (heat capacity, thermal conductivity, and thermal expansion), acoustical, dielectric, and viscoelastic, which maintain the physical properties of polymers at low temperatures. Comprised of nine chapters, this book first covers heat capacity of polymers at low temperature, and then tackles thermal conductivity of polymers at low temperatures. Chapter 3 discusses thermal expansion of polymers at low temperatures, and Chapter 4 tackles electrical properties of polymers at low temperatures. The fifth chapter covers nuclear magnetic resonance in polymers at low temperature, while the succeeding chapter encompasses dynamic mechanical properties of polymers at low temperatures. Chapter 7 concerns itself with the acoustical properties of polymers at low temperatures, while the succeeding chapter covers viscoelastic parameters of polymers at low temperatures. The closing chapter covers how to determine the thermophysical characteristics of polymers by acoustic measurement at helium temperature. This book will be of great interest to researchers or professionals whose line of work involves the manipulation and understanding of the properties of polymers.
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 Thermal Properties of Solids at Room and Cryogenic Temperatures by : Guglielmo Ventura
Download or read book Thermal Properties of Solids at Room and Cryogenic Temperatures written by Guglielmo Ventura and published by Springer. This book was released on 2014-06-23 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The minimum temperature in the natural universe is 2.7 K. Laboratory refrigerators can reach temperatures in the microkelvin range. Modern industrial refrigerators cool foods at 200 K, whereas space mission payloads must be capable of working at temperatures as low as 20 K. Superconducting magnets used for NMR work at 4.2 K. Hence the properties of materials must be accurately known also at cryogenic temperatures.

Book Synopsis Thermal/Mechanical Response of a Polymer Matrix Composite at Cryogenic Temperatures by : National Aeronautics and Space Administration (NASA)
Download or read book Thermal/Mechanical Response of a Polymer Matrix Composite at Cryogenic Temperatures written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-11 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order for polymeric-matrix composites to be considered for use as structural materials in the next generation of space transportation systems, the mechanical behavior of these materials at cryogenic temperatures must be investigated. This paper presents experimental data on the residual mechanical properties of a carbon-fiber polymeric composite, IM7/PETI-5, both before and after aging. Both tension and compression modulus and strength were measured at room temperature, -196C, and -269 C on five different laminate configurations. One set of specimens was aged isothermally for 576 hours at -184 C in an unconstrained state. Another set of corresponding specimens was aged under constant uniaxial strain for 576 hours at -184 C. Based on the experimental data presented, it is shown that trends in stiffness and strength that result from changes in temperature are not always smooth and consistent. Moreover, it is shown that loading mode and direction are significant for both stiffness and strength, and aging at cryogenic temperature while under load can alter the mechanical properties of pristine, un-aged laminates made of IM7/PETI-5 material.Whitley, Karen S. and Gates, Thomas S.Langley Research CenterTEMPERATURE EFFECTS; POLYMER MATRIX COMPOSITES; CRYOGENIC TEMPERATURE; COMPRESSIVE STRENGTH; TRENDS; STIFFNESS; SPACE TRANSPORTATION SYSTEM; ROOM TEMPERATURE; LOADS (FORCES); CARBON FIBERS

Book Synopsis Heat Capacity and Thermal Expansion at Low Temperatures by : T.H.K. Barron

This book was released on 2012-12-06 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The birth of this monograph is partly due to the persistent efforts of the General Editor, Dr. Klaus Timmerhaus, to persuade the authors that they encapsulate their forty or fifty years of struggle with the thermal properties of materials into a book before they either expired or became totally senile. We recognize his wisdom in wanting a monograph which includes the closely linked properties of heat capacity and thermal expansion, to which we have added a little 'cement' in the form of elastic moduli. There seems to be a dearth of practitioners in these areas, particularly among physics postgraduate students, sometimes temporarily alleviated when a new generation of exciting materials are found, be they heavy fermion compounds, high temperature superconductors, or fullerenes. And yet the needs of the space industry, telecommunications, energy conservation, astronomy, medical imaging, etc. , place demands for more data and understanding of these properties for all classes of materials - metals, polymers, glasses, ceramics, and mixtures thereof. There have been many useful books, including Specific Heats at Low Tempera tures by E. S. Raja Gopal (1966) in this Plenum Cryogenic Monograph Series, but few if any that covered these related topics in one book in a fashion designed to help the cryogenic engineer and cryophysicist. We hope that the introductory chapter will widen the horizons of many without a solid state background but with a general interest in physics and materials.

Book Synopsis Mechanical Properties of Materials at Low Temperatures by : D. Wigley
Download or read book Mechanical Properties of Materials at Low Temperatures written by D. Wigley and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: In writing this monograph, the aim has been to consider the mechanical properties of the wide range of materials now available in such a way as to start with the fundamental nature of these properties and to follow the discussion through to the point at which the reader is able to comprehend the significance or otherwise of the large amounts of data now available in design manuals and other compilations. In short, it is hoped that this volume will be used as a companion to these data compilations and as an aid to their interpretation. In attempting to cover such a wide field, a large degree of selection has been necessary, as complete volumes have been written on topics which here have had to be covered in a few pages or less. It is inevitable that not everyone will agree with the choice made, especially if it is his own subject which has been discussed rather briefly, and the author accepts full res ponsibility for the selection made. The book is written at a level which should be easily followed by a university graduate in science or engineer ing, although, if his background has not included a course in materials science, some groundwork may be lacking.

Download or read book Going for Cold written by J. G. Weisend II and published by Springer Nature. This book was released on 2021-03-03 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This short but revealing biography tells the story of Kurt Mendelssohn FRS, one of the founding figures in the field of cryogenics, from his beginnings in Berlin through his move to Oxford in the 1930s, and his groundbreaking work in low temperature and solid state physics. He set up the first helium liquefier in the United Kingdom, and did fundamental research that increased our understanding of superconductivity and superfluid helium. Dr. Mendelssohn's vision extended beyond his scientific and technical achievements; he saw the potential for growth of cryogenics in industry, visiting China, Japan and India to forge global collaborations, founded the leading scientific journal in the field and established a conference series which still runs to this day. He published two monographs which remain as classics in the field. This book explores the story behind the science, in particular his relationships with other key figures in the cryogenics field, most notably Nicholas Kurti at Oxford, and his work outside cryogenics, including his novel ideas on the engineering of the pyramids.
