Book excerpt: The General Electric (GE) Co., Thermal Systems Programs, in Tacoma, Wash., has developed a medium-density rigid structural polyurethane foam insulation material to withstand thermal stresses imposed by temperatures down to absolute zero 0 K (-460°F). Structural test results according to ASTM standards are presented for tensile, compressive, and shear strength and moduli. Other structural properties presented are Poisson's ratio and creep characteristics. Thermal test results according to ASTM standards are presented for thermal conductivity and expansion/contraction. Foam thermal/structural performance at cryogenic temperatures as low as LN2 (liquid nitrogen) and LH2 (liquid hydrogen) conditions, 77 K (-320°F) and 22 K (-420°F), respectively, are also related. Applications for liquefied natural gas (LNG) ships and LH2 fueled subsonic transport aircraft are discussed. In part, a lot of technical information presented herein was used to obtain conceptual approval complete from the U.S. Coast Guard for the insulation of LNG ships utilizing GE cryogenic polyurethane foam.

This book was released on 2012-12-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This, the second special topical conference on the properties of Non-Metallic Materials at Low Temperatures, was sponsored by the International Cryogenic Materials Conference Board. The potential for plastics materials in the field of cryogenics is vast and as yet only partly explored. In addition, many other materials, which qualify for the title non-metallic but are not 'plastics', have numerous possible outlets in low temperature technology. This conference aimed at providing a forum, whereby specialists from Industry, the Universities and from Government sponsored Institutions could assemble to discuss the extent of our current knowledge. As it transpired, the meeting was also to high light the considerable gaps that still exist in our fundamental understanding of the low temperature behaviour of these materials. On this theme, during the course of the conference, a reference was made to an almost forgotten quotation by Lord Kelvin, who said: "When you cannot measure what you are speaking about, when you cannot express in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the stage of a science, whatever the matter be." This simple statement sums up the aims, objectives and hopefully the achievements of this conference. To discuss and disseminate the current knowledge on non-metallic materials in order that realistic predictions of in-service performance may be made.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: There is a continuing need for improved rigid foam insulation, particularly for cryogenic storage aboard aerospace vehicles. The present work is a material characterization of spray-on foam insulation used on the Space Shuttle External Tank. The characterization includes imaging and measurements of thermal conductivity, ultimate tensile strength, and moisture absorption. Thermal conductivity measurements are the main focus of the present work, as it is the most relevant property to insulation performance. A novel apparatus was developed to measure the thermal conductivity of rigid foam at temperatures ranging from 20 K to 300 K with a ÄT of 10 K between the sides of the foam sample. The effective thermal conductivity of three samples of NCFI 24-124 foam insulation was measured over the full temperature range. Additionally, the effects of different residual gases and moisture absorption on the thermal conductivity of the foam were studied. The data were compared to data from the literature and to mathematical models developed to predict the thermal conductivity. The data show that gas condensation can play a significant role in the thermal conductivity of the foam at low temperature. Moisture absorption can occur in the foam in application when cryogenic fuel is filled into a tank which sits in a warm, humid environment. An apparatus was developed to subject foam samples to these conditions. The moisture content in the samples was then measured. The samples were then imaged using the 900 MHz NMR magnet at the National High Magnetic Field Laboratory to determine the location of the water within the foam. Samples conditioned for 9 hours exhibited a 50% weight increase, and samples conditioned for 69 hours exhibited a 284% weight increase. The NMR images showed that the moisture collects first near the warm side of the foam, and permeates through the foam over time. However, the moisture appears to not collect near the knit lines (areas between sprayed layers of foam, containing cells about 10 times smaller than those that make up the bulk of the foam). The 100 kN mechanical testing system at the NHMFL was used to measure the ultimate tensile strength of the foam. The number of samples available limited the amount of measurements, but the data show that the orientation of the foam (parallel or perpendicular to the knit lines) has a greater effect on the tensile strength than does the moisture absorption or exposure to cryogenic temperature.
