Nice example of a tensile test performed on a carbon fibre of diameter 6.5 µm using the Alemnis Fibre Clamp Kit (WKT). Experiment in displacement control with a speed of 1 µm per second. Fibre failed at a load of 138 mN and at a maximum stress of 4.1 GPa and maximum strain of 10%. Initial gauge length was 573 µm.
