Abstract

This report details requirements for the development of test methods for characterising the strain rate dependent mechanical properties of fibre-reinforced polymer (FRP) composite materials. The focus is on the use of high-speed servo-hydraulic test machines for measuring properties at ‘intermediate’ strain rates, i.e. between 0.1 and 100 s-1. Insights have been drawn from interviews held with experts across the composites and materials testing landscape, alongside a systematic literature review. Measurement challenges preventing progress towards standardisation of methods have been highlighted and recommendations on activity and good practice guidance to overcome these challenges are provided.
