Experimental analysis demonstrates fiberglass composite neck's compatibility with liquid nitrogen, suggesting advantages over metals.
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.
