Abstract

For investigations on material behavior at higher strain rates (more than 100 1/s and less than 1000 1/s), no method has yet been described for high-performance fibers due to their low elongation at break. The expected elongation at break determines the maximum distance that can be covered until the test speed has been reached during the acceleration phase. This shortens the time available for accelerating the sample as well as for recording of the forces. It will be shown that, with the help of a rotary drive, it is possible to characterize the material behavior even at higher strain rates. This drive allows the optional adjustment of the testing speed between 10 and 100 m/s, thus, in combination with specimen lengths of 100 to 200 mm, strain rates of 50 to 1000 1/s can be achieved.
