N2 - In this work, consolidated composite blanks of carbon fibre/polyether ether ketone (CF/PEEK) were stamped until failure with a hemispherical punch under various temperatures. Real-time strain measurements were extracted using three-dimensional photogrammetry. The results were evaluated with benchmarks used in metal forming. These were then compared to aluminium blanks formed under similar conditions. Under certain circumstances, the composite exhibited comparable formability to aluminium. This is particularly significant, as CF/PEEK is a high performance composite with superior specific mechanical properties compared to monolithic metal alloys. These results highlight the potential for composites such as this to replace heavier metals in various industries, without sacrificing performance or increasing manufacturing expenses.
