Form-fitting clamping
Specimens are clamped by a form-fitting connection; an inlay allows one standardised clamping device for different head geometries.
High-Speed Tensile Impact
Hegewald & Peschke Rotational Impact Tester
Highly dynamic tensile tests on fibre composites, technical textiles and bonding points
The Rotational Impact Tester from Hegewald & Peschke runs highly dynamic tensile impact tests at 1 to 14 m/s, giving strain rates up to 350 s⁻¹ for crash-relevant material data.

Overview
Flywheel energy for tensile tests in milliseconds
The rotational impact tester is used for highly dynamic tensile impact tests with high speed and a long linear test path, mainly on fibre composites, technical textiles, seams, glued joints and bonding points.
A 300 kg rotating flywheel mass stores the energy, which is transferred to a linear slide with an integrated specimen holder. The tensile test takes only a few milliseconds, while force, displacement and time are recorded. Strain rates up to 350 s⁻¹ simulate material behaviour in crash conditions such as 50 km/h (14 m/s).
The machine is operated by a touch panel. Measured data is held in buffer memory and transferred automatically to LabMaster software for evaluation and traceable data backup.
