Material Testing

Core task of the Department Material Testing is the comprehensive destructive and non-destructive characterisation of material and component samples to obtain knowledge about processing properties, application oriented material performance, failure behaviour and degradation behaviour. Testing is focused on plastics and fibre-reinforced plastics, but is not limited to these materials.

Besides established methods, for example for the standard-compliant determination of mechanical characteristics, also novel methods are developed.

The Department Material Testing comprises:

MECHANICAL MATERIAL TESTING

For the determination of mechanical material characteristics we are able to conduct, among others, tensile, compression, bending and impact bending tests with a state-of-the-art testing machinery, under standard atmosphere as well as under temperature control. This is complemented by tests for the determination of the heat deflection temperature, creep tests for the investigation of the long-term creep behaviour and dynamic-mechanical tests for the characterisation of the fatigue behaviour. 

IMAGING ANALYSIS

Using 3D digital microscopy and scanning electron microscopy (SEM) samples can be imaged on different scales and with resolutions down to the single-digit nanometre range. By applying energy-dispersive X-ray spectroscopy (EDX) in SEM investigations also elemental contents and distributions in samples can be determined space-resolved.

A particle and fibre measurement system enables the 2-dimensional measurement of geometrical properties of particles and fibres starting at diameters of about 10 µm.

The micro-computed tomography provides a 3-dimensional representation of material samples and components with a detail recognizability down to the (sub-)micrometre range. As a non-destructive technique the method is especially suited to capture the condition of a sample repeatedly over the duration of an experiment and by this track changes inside the samples over time.

ENVIRONMENTAL TESTING AND DEGRADATION EXPERIMENTS

For the examination of material behaviour under environmental impacts during, as well as after the utilisation phase experimental setups for the accelerated weathering and the simulation of degradation in the environment are available.

DESIGN OF EXPERIMENTS

By design of experiments the significant parameters in extensive studies with a large number of experimental parameters can be identified to significantly reduce the experimental testing effort.
