摘要

Suppression of dimensional change induced by moisture and temperature changes is studied for perfectly bonded, unbalanced, parallel fibrous structures composed of at least one hygroscopic component, taking into account various parameters such as initial moisture content and temperature at the time of assembly, width or height ratio of the tow components, molecular orientation, and bonding length. The results show that two factors play major roles in moisture/temperature induced dimensional (curvature) change: longitudinal fiber swelling/shortening and material softening/stiffening.
