The aim of this paper is to describe how a dynamic mechanical analyser can be used together with the microwave coaxial line
technique. This coupling enables the simultaneous recording of changes in the mechanical properties and moisture content of
materials as a function of time or temperature at a selected frequency. The sample is placed either directly under the probe
or clamped in the sample holder of the dynamic mechanical analyser. Sample positioning and heating is accurately controlled
by the mechanical analyser and its temperature controller. Samples can be subjected to a constant static force, a frequency
or both. A micro probe, recently designed for measurements on semi-rigid and rigid surfaces , and connected to a network
analyser was used to monitor the moisture content of the samples.
