This book was released on 1967 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The experimental investigation was concerned with understanding the mechanisms by which fibrous insulations attenuate the transfer of thermal energy. Three fibrous insulation materials, Dynaquartz, Sapphire Wool, and Dynaflex, were evaluated for their usefulness in the high temperature environment. Effective thermal conductivities were measured in air, argon, and vacuum up to 2500 deg F. Transmission experiments were carried out to evaluate the relative contribution of radiation attenuation parameters for Dynaquartz.

Book excerpt: The objective of this research is to gain a better understanding of the various mechanisms of heat transfer through fibrous materials and to gain insight into how fill-gas pressure influences the effective thermal conductivity. By way of first principles and some empiricism, two mathematical models are constructed to correlate experimental data. The data are obtained from a test series measuring the effective thermal conductivity of Nomex using a two-sided guarded hot-plate heater apparatus. Tests are conducted for certain mean temperatures and fill-gases over a range of pressures varying from vacuum to atmospheric conditions. The models are then evaluated to determine their effectiveness in representing the effective thermal conductivity of a fibrous material. The models presented herein predict the effective thermal conductivity of Nomex extremely well. Since the influence of gas conduction is determined to be the most influential component in predicting the effective thermal conductivity of a fibrous material, an improved representation of gas conduction is developed. Finally, some recommendations for extension to other random-oriented fiber materials are made concerning the usefulness of each model depending on their advantages and disadvantages.

Available in PDF, EPUB and Kindle. Book excerpt: Thermophysics: Applications to Thermal Design of Spacecraft is a collection of technical papers presented at the American Institute of Aeronautics and Astronautics's 7th Aerospace Sciences Meeting, held on January 20-22, 1969, in New York and 4th Thermophysics Conference, held on June 16-18, 1969, in San Francisco, California. Contributors explore the applications of thermophysics to thermal design of spacecraft and tackle topics ranging from conduction and radiation to convection, phase change, and thermal design techniques. Comprised of 26 chapters, this volume begins with a discussion on experimental thermophysical properties, focusing on topics such as contact thermal resistance theory and experiment; optics and engineering in thermophysics; and crystal growth during melting and freezing and its application to phase change in thermal control. The physical parameters affecting radiation property degradation under simulated space environmental conditions are also considered. Radiative analysis is treated in the next section, with emphasis on surface effects upon radiative properties; two-component heat pipes; parametric thermal control requirements for future manned spacecraft; and thermal considerations of a landed vehicle on the surface of Mars. This book should be of interest to practitioners in astronautics and aeronautics.

This book was released on 2011-04-19 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of fibrous materials in civil engineering, both as structural reinforcement and in non-structural applications such as geotextiles, is an important and interesting development. Fibrous and composite materials for civil engineering applications analyses the types and properties of fibrous textile and structures and their applications in reinforcement and civil engineering.Part one introduces different types of fibrous textiles and structures. Chapters cover the properties of natural and man-made fibres and of yarns, as well as an overview of textile structures. Part two focuses on fibrous material use in concrete reinforcement, with chapters on the properties and applications of steel fibre reinforced concrete, natural fibre reinforced concrete and the role of fibre reinforcement in mitigating shrinkage cracks. In part three, the applications of fibrous material-based composites in civil engineering are covered. Chapters concentrate on production techniques and applications such as reinforcement of internal structures, structural health monitoring and textile materials in architectural membranes.With its distinguished editor and international team of contributors, Fibrous and composite materials for civil engineering applications is a standard reference for fabric and composite manufacturers, civil engineers and professionals, as well as academics with a research interest in this field. - Explores the development of fibrous materials in civil engineering, both as structural reinforcement and in non-structural applications such as geotextiles - Key topics include short fibre reinforced concrete, natural fibre reinforced concrete and high performance fibre reinforced cementitious composites - A standard reference for fabric and composite manufacturers, civil engineers and professionals, as well as academics with a research interest in this field
