Composite Testing Technology

Our mission

Grasse Zur Composite Testing specialises in the testing of fibre-reinforced plastics and operates an ISO 17025 accredited materials testing laboratory at its site in Berlin. The tests include all relevant procedures in the field of destructive and non-destructive testing and thermal analysis. In addition, the company develops reference test fixtures for material testing, manufactures the online process control GZ US-Plus® for monitoring incoming goods and for production of components made of thermoset plastics and offers professional seminars 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.

Differences between the thermoanalytical methods DSC and DMA

For many years, Grasse Zur Composite Testing has been carrying out thermoanalytical tests on fibre-reinforced plastics in order to provide clients with information on the curing state of the test specimen material. The materials are usually thermoset plastics made of EP or VE resin systems. Either DSC or DMA analysis is used for the investigations (determination of the glass transition temperature, the degree of curing, the melting temperature and the enthalpy of fusion).

Both test methods can be used to determine the current and the maximum glass transition temperature. However, the analysis technique and the test results differ significantly. The article compares the two test methods.
