Characterization of Fiberglass Reinforced Resin Tube for its Application in a Cryogenic Container

The progress in cryogenic applications is strongly dependent on advances in the development of materials. It is revealed from the available literature that most often the suitability of a large number of metals and alloys has been studied but much less work is reported about components made of resin-impregnated fiberglass composites which may have a reasonable edge over many metallic components for cryogenic and allied applications. In this regard, a fiberglass composite neck is fabricated and its suitability for application as the neck of a liquid nitrogen container is studied. The paper presents various physiochemical characterizations such as XRD, SEM of the material, and successful testing of the fiberglass composite neck in situ in a liquid nitrogen environment towards its compatibility at cryogenic temperature.
