Testing fiber composites at ultra-low temperatures
Cryotechnology is used in many areas of materials testing. The aim is to identify material characteristics and gain insights into material behavior at extremely low temperatures.

The testing machine manufacturer ZwickRoell is changing the legal form of its parent company from a stock corporation (AG) to a European stock corporation (SE).

Klaus Cierocki will take over as CEO of ZwickRoell on April 1.

The European Organization for Nuclear Research CERN (Conseil Européen pour la Recherche Nucléaire) is one of the largest and most renowned centers for basic research in physics.
ZwickRoell's LTM series linear testing machines are designed for fatigue tests on composite materials. They can also be used for quasi-static tests.
Materials testing is becoming increasingly automated, as even the smallest disturbances change the measured values. Time-consuming or monotonous work is also increasingly being carried out by robots.
ZwickRoell has supplied a drop weight tester for impact tests to the Gövert testing laboratory in Essen with a height of around 9 meters, a weight of more than 10 tons and a drop energy of 120,000 joules. These data make it one of the most powerful drop weight testers in the world.

While certain error margins that do not affect product quality are tolerated in production, absolutely reliable test results are essential in the areas of material testing and quality assurance.

The German Aerospace Center conducts research in the fields of aviation, transportation, space and energy. As a leading institution in this field, the Institute of Composite Structures has been working for many years on more efficient manufacturing processes for CFRP structures as well as on improved analysis and design methods. In future, a ZwickRoell testing machine will be used for fatigue tests on CFRP-reinforced composites.

The advantages of automated quality control are accurate, reliable and reproducible test results. In addition, qualified laboratory personnel are freed up from routine tasks and are available for more complex tasks. A high sample throughput also leads to a reduction in testing costs. With RoboTest P and RoboTest R, Zwick offers two highly flexible solutions for automated quality control.

The 3D printing of lubrication- and maintenance-free bearings made from tribo-polymers enables a high degree of freedom in the design while at the same time ensuring the wear resistance of the components used. Thanks to extensive test series in its own test laboratory, Igus is able to predict the service life of the individually additively manufactured polymer bearing online. On this basis, customers can individually calculate their desired bearings online.
