Spezial testing machine for the material scientific characterisation of elastomers


Spezial testing machine inspekt S 5kN

In May 2014, the company Hegewald & Peschke MPT GmbH delivered a special testing machine for the material-scientific characterisation of elastomers to the institute for engineering mechanics of the Friedrich-Alexander University Erlangen-Nürnberg. The primary purpose is to research the time- and temperature depending behaviour of filed silicone elastomers under a wide range of testing conditions. By using a temperature chamber, it is also possible to test the specimens not only under normal environmental conditions, but also to carry out testings in a wide range of temperatures from -80 °C to +250 °C. In contrast to the standard testing machines of Hegewald & Peschke MPT GmbH, the testing frame including the pneumatic clamping device is not made of steel, but of aluminium and other non-magnetisable materials. This allows carrying out testings under the influence of magnetic fields for the characterisation of magneto-sensitive elastomers (MSE). The recording of the path data during the experiments is ensured by means of a video extensometer. Thanks to the contact-free data recording it is also possible to carry out Tests under a temperature influence between -80 °C and +250 °C and under the influence of magnetic fields. Currently, the integration of the magnetic field is in the development phase at the customer. The aim of the research project with the entire system is to gain fundamental knowledge about the uniaxial behaviour of filled, and particularly of magneto-sensitive silicone elastomers under a wide range of environmental influences.
