Impact tester for composites and textiles - 2

Application:  Highly dynamic tensile tests with a long linear test path  Testing of fibre composites and technical textiles (optionally extendable with other rotation masses for other materials)  Testing of bonding points (e.g. seams, glued joints)  Realisation of strain rates up to 350 s-1 Material characteristics at such high strain rates are used for crash simulations, e.g. in lightweight construction or in the automotive industry. They simulate the material behaviour at 50 km/h (14 m/s). Functionality: In this rotational impact tester, a 300 kg rotating flywheel mass is decisive for...

Impact tester for composites and textiles - 4

Operation, data transmission, operation of the rotational impact tester: Comparison of testing machines with similar applications: In this test series, the rotational impact tester impresses with its high testing speed and high impact energy, at a comparatively small machine size. Impact energy Rotational impact tester up to 16,000 J Test energy is defined by flywheel mass and test speed Testing speed Test forces + Specific setting of relatively high test speeds + small space requirement + relatively high test forces + high energies despite small flywheel mass (300 kg) - no standardised...
