Abstract

This report details requirements for the development of bespoke equipment for characterisation of the mechanical performance of fibre-reinforced polymer (FRP) composite materials at cryogenic temperatures down to -269°C (4 K), the boiling temperature of liquid helium at atmospheric pressure.

The report presents the progress of the first stage of work to specify cryogenic test equipment for FRP composites within the National Measurement System (NMS) project “Polymer Composites Metrology in Support of Regulations, Codes and Standards (RCS) Infrastructure”, undertaken by the Advanced Engineering Materials (AEM) Group at the National Physical Laboratory (NPL). The project’s key objectives are to develop capability suitable for investigating the mechanical properties at cryogenic temperatures of composite materials used in hydrogen and liquid natural gas (LNG) distribution and storage applications.

The information provided in the report has been collated with inputs from extensive interviews conducted over a period of 9 months with renowned experts within the cryogenics and materials testing fields across Europe and the USA, alongside relevant literature, and existing standards reviews.
