Our mission

Grasse Zur Composite Testing specialises in the testing of fibre-reinforced plastics and operates a materials testing laboratory accredited according to ISO 17025 at its Berlin site. In addition, the company develops reference test fixtures for material testing, manufactures the GZ US-Plus® online process control for monitoring incoming goods and production, and offers professional seminars and training courses on all aspects of composite testing in cooperation with experienced lecturers.

Our claim

At Grasse Zur Composite Testing, the quality of material testing for fibre-reinforced plastics is the top priority. The entire team works together to continuously improve the processes in order to guarantee a consistently high quality of material testing. This includes achieving the best test results with the lowest possible standard deviations, testing according to in-house specifications that clearly exceed the requirements specified in the respective test standards, fast and proactive communication with the customers and adherence to the agreed delivery dates with maximum flexibility and fair prices at the same time.

Composite Testing News

Test stand for missile tanks

Grasse Zur Composite Testing has developed a test rig for LOX (“liquid oxygen”) tests together with MT Aerospace. CFRP tanks are cooled down to approx. -180 °C, pressurised and tested via the introduction of impacts.

The tests show that lightweight carbon-fibre reinforced plastic is strong enough to replace metal used in upper-stage rocket structures. This is an important milestone in Europe for the development of a prototype of a highly-optimised ‘black’ upper stage, Phoebus, a joint initiative by MT Aerospace and ArianeGroup, funded by ESA’s Future Launchers Preparatory Programme.

Further information

Professional seminars at the end of 2021

At the end of 2021, some of the tried and tested professional seminars on the subject of testing fibre-reinforced plastics will still be taking place. The events are held in compliance with special hygiene and protection measures, and the number of participants is strictly limited.

If you would like to participate in one of the following seminars, you should register as soon as possible under the respective link, as the number of free places is very limited this year. You can download the complete seminar program here. There is a special discount for Composites United member companies.
