Abstract

Journal of Reinforced Plastics and Composites, Ahead of Print.
Thermal stresses and residual deformations in composite structures arise from the mismatch in the coefficients of thermal expansion (CTE) between fibers and the resin, chemical shrinkage during curing, and non-uniform temperature distributions through the ...
