Coefficient of Moisture Expansion:
A challenging measurement task
A high degree of dimensional stability is often required for aircraft and spacecraft components. In order to evaluate polymeric composite materials for aerospace applications the coefficients of thermal expansion (CTE) and moisture expansion (CME) have to be determined. Coefficient of Moisture Expansion (CME) is defined as the ratio of change in strain and mass variation due to the moisture desorption or absorption. For the determination of the CME the change of length and the mass [...]
