Evaluation of Microcracking in Two Carbon-Fiber/Epoxy-Matrix Composite Cryogenic Tanks - Bog af A J Hodge - Paperback

Evaluation of Microcracking in Two Carbon-Fiber/Epoxy-Matrix Composite Cryogenic Tanks - Bog af A J Hodge - Paperback

Two graphite/epoxy cryogenic pressure vessels were evaluated for microcracking. The X-33 LH2 tank lobe skins were extensively examined for microcracks. Specimens were removed from the inner skin of the X-33 tank for tensile testing. The data obtained from these tests were used to model expected microcrack density as a function of stress. Additionally, the laminate used in the Marshall Space Flight Center (MSFC) Composite Conformal, Cryogenic, Common Bulkhead, Aerogel-Insulated Tank (CBAT) was evaluated...

Pwtb 420-49-35 - In-Situ Epoxy Coating for Metallic Pipe - Bog - Paperback

The United States Army Corps of Engineers (USACE, also sometimes shortened to CoE) is a U.S. federal agency under the Department of Defense and a major Army command made up of some 38,000 civilian and military personnel, making it the world's largest public engineering, design, and construction management agency. Although generally associated with dams, canals and flood protection in the United States, USACE is involved in a wide range of public works throughout the world. The Corps of Engineers..

The NASA Technical Reports Servcr (NTRS) houses half a million publications that are a valuable means of information to researchers, teachers, students, and the general public. These documents are all aerospace related with much scientific and technical information created or funded by NASA. Some types of documents include conference papers, research reports, meeting papers, journal articles and more. This is one of those documents.

Development of Standards for Nondestructive Evaluation of Copvs Used in Aerospace Applications - Bog - Paperback

Development of Standards for Nondestructive Evaluation of Copvs Used in Aerospace Applications - Bog - Paperback

Composite OverWrapped Pressure Vessels (COPVs) are currently accepted by NASA based on design and qualification requirements and generally not verified by NDE for the following reasons: (1) Manufactures and end users generally do not have experience and validated quantitative methods of detecting flaws and defects of concern (1-a) If detected, the flaws are not adequately quantified and it is unclear how they may contribute to degradation in mechanical response (1-b) Carbon-epoxy COPVs also extremely..

Reliability of Copvs Accounting for Margin of Safety on Design Burst - Bog af Pappu L N Murthy - Paperback

Reliability of Copvs Accounting for Margin of Safety on Design Burst - Bog af Pappu L N Murthy - Paperback

In this paper, the stress rupture reliability of Carbon/Epoxy Composite Overwrapped Pressure Vessels (COPVs) is examined utilizing the classic Phoenix model and accounting for the differences between the design and the actual burst pressure, and the liner contribution effects. Stress rupture life primarily depends upon the fiber stress ratio which is defined as the ratio of stress in fibers at the maximum expected operating pressure to actual delivered fiber strength. The actual delivered fiber strength..
