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.
