Thermomechanical Analysis TMA

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.
