Abstract

Journal of Reinforced Plastics and Composites, Ahead of Print.
GFRP laminates used in water-immersed hydroelectric applications, such as turbine stay vane extensions, are prone to hygrothermal-induced mechanical degradation. This paper develops and validates a one-way coupled diffusion–degradation framework for six ...
