Thermally-induced responses of triaxially woven fabric composites

The article examines the thermal responses of one-ply triaxially woven fabric composites (TWFCs). A temperature change experimental observation is first conducted on plate and slender strip specimens of TWFCs. Computational simulations are then performed with analytical and simple, geometrically-similar model configurations to capture thereby offering insights into the anisotropic thermal effects of the experimentally observed deformation. It is revealed that the leading cause of the observed thermal responses is the advancement of a locally formed twisting deformation mode. Therefore, a newly defined thermal deformation description called the coefficient of thermal twist is then characterized for TWFCs for different loading cases.
