Abstract

Hygrothermal studies were carried out on unidirectional (UD) carbon fiber epoxy (LY 5052) composites at Vf = 0.5 and have been carried out for three different cases, viz. 45 C/85 pct RH, 45 C /95 pct RH, and 45 C/immersion (100 pct RH) till saturation is reached. In all cases, composite specimens of different test configurations, Longitudinal Tensile (LT), Transverse Tensile (TT), Longitudinal Compression (LC), and Transverse Compression (TC), were subjected to the above conditions, and their diffusion behavior was studied. Generally, the specimens under the above conditions exhibited Fickian diffusion behavior.
