Test Centre

Our Test Centre offers a wide range of services. Through application of the latest measurement technology and compliance to the current state of science, our competent staff succeeds to maintain reliable test results according to national and international standards. The close cooperation with the Institute of Lightweight Engineering and Polymer Technology (ILK) of the TU Dresden provides access to the latest scientific findings as well as to manufacturing and testing technologies.

In addition to a variety of standard tests, we offer development and application of new test methods for materials, components and systems. Selected test methods can be performed in our accredited laboratory (according to DIN EN ISO 17025). On request, we may also gain accreditation for further standard or proprietary test methods. Non-destructive testing of materials and components for quality control or failure detection complete our service portfolio.

This comprehensive expertise makes us the ideal partner for your testing projects.

Standardised test procedures

Our laboratory offers a wide range of tests according to national and international standards for all kinds of industry. Our team possesses extensive experience in performing standardised tests on almost all modern material classes. For mechanical tests, we use classical deformation measurement methods (such as strain gauges) as well as advanced optical measurement methods (for example greyscale correlation). Almost all experiments can be performed at defined temperatures (-60 °C to 250 °C) and climates. For determination of physical properties such as the thermal or rheological behaviour, we use various methods, for example DSC, TGA or plate rheometer. We proof our qualifications through regular participation in round robin tests.

Innovative test procedures

The rapid and dynamic development in the lightweight engineering sector increasingly calls for the application of special tests for determining specific material characteristics. Due to the increasing complexity of design and simulation criteria, input parameters, surpassing the classical material properties such as strength and stiffness, are required. The high demands on the quality of results require the continuous development and improvement of established procedures. Using current scientific knowledge, we offer customised solutions for your problems.

Our services:

  • Conception, design and detailed construction of test devices
  • Numerical preliminary examinations and test related simulation
  • Definition of evaluation methods and routines
  • Development of specimen geometries for generation of defined loading conditions and failures

Examples of novel test methods

We are continuously working on the improvement and expansion of testing methods. The following methods demonstrate a selection of tests we perform successfully:

Material testing

The design process is based on the knowledge of failure and damage phenomena occurring in the material, especially when using modern lightweight materials and connection techniques. Our laboratory provides services to test your materials in accordance with current national and international standards or according to customer requirements. Furthermore, we can determine material characteristics, which go beyond the classical material properties such as strength and stiffness.

Material modelling

Accompanying the performed characterisation tests, we also offer modelling of the material behaviour. The FE-based simulation of the experiment increases the understanding of the measured data. In this way, the damage history can be traced. Furthermore, we can implement a computer-aided design of your components with the material cards created and validated for you.

With our vibration decoupled clamping field, we can implement all your test requirements for static and cyclic testing. For the testing of components from aerospace, automotive and marine industries, we offer a wide range of customised test benches which can be adapted to our customers’ requirements if necessary. Furthermore, diverse climate and pressure chambers for the test procedure and specific climatic change tests can be used.

Non-destructive testing

It is not always expedient to perform destructive tests on specimens. Non-destructive test methods have been established especially in the area of quality assurance and damage detection. Through these test methods, externally invisible defects and the internal structure of the material can be analysed without damaging the specimens. Certain methods can be carried out in combination with a destructive test, which allows more detailed conclusions concerning the failure behaviour. We master a wide range of non-destructive testing methods; therefor we offer a comprehensive review of manufacturing processes, determination of damage incidents and measures of quality assurance.

Our services:

  • Ultrasound (air and water coupled)
  • 3D-digitisation (ATOS®)
  • CT and In-situ CT
  • Thermography
  • Profilometry
  • Optical microscopy and scanning electron microscopy
