Thermomechanical Analysis (TMA):
Thermomechanical analysis is the measurement of a material’s behaviour, ie. expansion or
contraction, when temperature and a load is applied. A scan of dimensional changes related
to temperature (at constant load) or load (at constant temperature) provides valuable
information about the sample’s mechanical properties. One of the most important
applications of TMA is the characterization of composite and laminate materials, through the
study of glass transition temperature and the expansion coefficient. Another application is in
the quantitative measurement of extension and contraction observed in textile fibres, thin
films and similar materials.
