Abstract
Split Hopkinson Tension Bars are used to test materials at high strain rates under tensile loading. For carbon fiber reinforced composites commonly the specimen are mounted using glued end caps. An alternative mounting concept is presented. The quality of the test results is evaluated using Finite Element Simulations and comparing real test results with two different mountings. The results showed that for low striker velocities of 4 m/s the alternative mounting is suitable. With this alternative approach other specimen dimensions are possible and the testing is less time consuming.
