This book was released on 2018-11-06 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: These guidelines address the electrical properties of composite materials which may have an effect on electromagnetic compatibility (EMC). The main topics of the guidelines include the electrical shielding, fault current return, and lightning protection capabilities of graphite reinforced polymers, since they are somewhat conductive but may require enhancement to be adequate for EMC purposes. Shielding effectiveness depends heavily upon the conductivity of the material. Graphite epoxy can provide useful shielding against RF signals, but it is approximately 1,000 times more resistive than good conductive metals. The reduced shielding effectiveness is significant but is still useful in many cases. The primary concern is with gaps and seams in the material just as it is with metal. Current carrying capability of graphite epoxy is adequate for dissipation static charges, but fault currents through graphite epoxy may cause fire at the shorting contact and at joints. The effect of lightning on selected graphite epoxy material and mating surfaces is described, and protection methods are reviewed. Evans, R. W. Marshall Space Flight Center...

Book excerpt: These proceedings contain research papers that were accepted for presentation at the 14th International Conference Inter-Eng 2020 ,Interdisciplinarity in Engineering, which was held on 8–9 October 2020, in Târgu Mureș, Romania. It is a leading international professional and scientific forum for engineers and scientists to present research works, contributions, and recent developments, as well as current practices in engineering, which is falling into a tradition of important scientific events occurring at Faculty of Engineering and Information Technology in the George Emil Palade University of Medicine, Pharmacy Science, and Technology of Târgu Mures, Romania. The Inter-Eng conference started from the observation that in the 21st century, the era of high technology, without new approaches in research, we cannot speak of a harmonious society. The theme of the conference, proposing a new approach related to Industry 4.0, was the development of a new generation of smart factories based on the manufacturing and assembly process digitalization, related to advanced manufacturing technology, lean manufacturing, sustainable manufacturing, additive manufacturing, and manufacturing tools and equipment. The conference slogan was “Europe’s future is digital: a broad vision of the Industry 4.0 concept beyond direct manufacturing in the company”.

This book was released on 2019-10-25 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanocomposite materials are multiphase materials where the interactions between the different components are enhanced by their intimate contact. Indeed, this emerging class of innovative materials guarantees excellent macroscopic properties by taking advantage of the peculiar characteristics that nanometer-sized fillers give to a suitable matrix compared to those obtainable with the same fillers at micrometric dimensions. These innovative materials improve and extend the range of desirable properties. Diverse Applications of Organic-Inorganic Nanocomposites: Emerging Research and Opportunities s a pivotal reference source that provides vital research on the application of organic-inorganic nanocomposite materials within various professional disciplines and in different human activities.

Download or read book High Effectiveness Shielding Materials and Optimal Shield Design written by E. Greenspan and published by . This book was released on 1992 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: A preliminary investigation of the effectiveness of new composite materials under development for shielding against neutrons and photons is reported upon. These materials are made from a proper mix of powders of tungsten, titanium or zirconium hydride and boron carbide, all bonded by hydrogenous materials such as polyethylene or silicone based materials. The investigation is carried out with the aid of the shield optimization code SWAN by considering a simplified 40-cm-thick spherical shield with CI-252 source at its center. The shielding ability of the new, so-called polynated and siliconated, materials is found to be highly superior to that of shielding materials in common use. The flexibility in tailoring the mix of inelastic scatterers, elastic scatterers, neutron absorbers, and photon attenuators to one's shielding needs, along with the information on material effectiveness functions which can be calculated with a code such as SWAN, are expected to enable improvements in future shield designs.

Download or read book Low Cost Electromagnetic Shielding Using Drywall Composites Results of RFI Radio Frequency Interference Testing of a Shielding Effectiveness written by Peter F. Williams and published by . This book was released on 1987 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of developments in electronics technology, the need for electromagnetic shielding has increased. To reduce the cost of this shielding, new materials are needed. The U.S. Army Corps of Engineers, Fort Worth District (FWD), and the U.S. Army Construction Engineering Research Laboratory (USA-CERL) have developed composite materials which use standard, construction grade, aluminum foil-backed gypsum board in combination with either a metal mesh or lead foil. Special seams for these composites have been designed by U.S. Gypsum Company. USA-CERL evaluated the adequacy of each material and seam design by using radio frequency antennas and receivers to measure its shielding effectiveness when mounted in the wall of a shielded room. These evaluations showed that the composite panels met the specified requirement of 60 decibels (dB) of shielding. The composites were also shown to be adequate for most communications security applications. However, the addition of a seam decreased shielding by as much as 10 dB.
