This book was released on 1983 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant progress has been made in the last several years toward the production of highly conductive carbon filament. Graphitized carbon fibers, made from a variety of precursor materials such as PAN, pitch and benzene, have electrical conductivity in the range 10 to the -6 power -10 to the -7 omega m, tensile strength in the range 1-3 GPa, tensile modulus in the range 100-700 GPa and density in the range 1.8 -2.2 x 10 to the 3rd power kg/m cube. These properties suggest graphitized fibers may have potential as current carrying material for electrical power transmission. This paper reviews the physical reasons for the electrical and mechanical properties and evaluate prospects for better conductivity without degradation of mechanical properties. Chemical doping (intercalation) is found capable of achieving X5-15 improvements in conductivity with some degradation in tensile strength. Various applications for electrical power transmission usage are examined, i.e., underground and overhead conduction, underground pipe, overhead towers and submarine cable. Near term usage is most probable in towers and submarine cable where high strength to weight advantages may offset the good, but not great, fiber electrical conductivity. (Author).

Download or read book Study of the Effects of Accidentally Released Carbon/graphite Fibers on Electric Power Equipment. Program Final Report, June 5, 1978-June 5, 1980 written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The program to study the effect of accidentally released carbon fibers on electrical power equipment consisted of determining the vulnerability of system outage rates to carbon fiber contamination, and performing tests to quantitize the contamination required to cause flashover of external insulation. Part One of this final report describes an assessment of the vulnerability of power systems to accidentally released fibers from a composite burn. The assessment describes the effect of carbon fibers on individual component failure rates and discusses the effect the change in component failure rates has on the power system reliability. Part Two describes in detail testing performed to determine the vulnerability of external insulation to carbon fiber contamination. Testing consisted of airborne contamination tests on distribution insulators, limited tests on suspension insulators which are commonly used for transmission class voltages, and various tests to quantify the influence of fiber length, voltage stress, etc. on flashover characteristics. The data obtained and analysis performed during this project show that the change of system reliability due to an accidental release from burned carbon fiber composite is negligible.

Download or read book Concise Encyclopedia of Composite Materials written by A. Kelly and published by Elsevier. This book was released on 2012-12-02 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Concise Encyclopedia of Composite Materials, first published as a hardbound edition in 1989, has been updated and revised and is now available as a paperback for individual researchers requiring a fundamental reference source for this dynamic field. Since 1989, research involving composite materials has advanced rapidly and this revised edition reflects those changes with the addition of new articles, including recent work on nanocomposites, smart composite materials systems, and metallic multilayers. The 67 articles included in this revised edition are presented in alphabetical order and each provides an introduction to one aspect of composite materials. Every article is extensively cross-referenced and includes a full bibliography. The volume contains over 250 photographs, drawings and tables as well as exhaustive subject and author indexes. The comprehensive breadth of coverage of the field of composite materials makes this volume an invaluable source of reference for materials scientists and mechanical engineers involved in industrial and academic research into the fabrication, properties and applications of composite materials.
