N2 - It is well known that coefficients of thermal expansion and hygroscopic swelling vary with temperature. The most significant change takes place at the glass transition temperature of a polymer. The phenomenon of temperature-dependent CHS has been studied by several authors [1, 2] in polymers and polymer-based composites mainly at room temperature and above. However, effect of freezing temperature on hygroscopic swelling of polymers has not been demonstrated. In this study, the behavior of CHS at and below freezing temperature is investigated. Reported results are obtained using a new CHS measurement technique, the digital image correlation method.
