Abstract

Advanced materials underpin the development of storage and distribution technologies for liquid hydrogen a fuel on board an aircraft. Though it is necessary to have in place fit-for-purpose testing and characterisation methods that can accurately measure the required properties at the associated conditions. These need to include mechanical, thermal as well as transport properties of the associated materials. When it comes to mechanical testing, the method of the load introduction to the specimen is overly critical. In this work, a novel gripping system was developed, addressing issues that have been observed with traditional wedge action gripping, thus allowing for tensile testing of fibrous composite materials at cryogenic temperatures. Overall, the grips have been performing well when it comes to ease of use and function, however they were found to be susceptible to local grip-face damage when testing harder materials.
