Study of statistically significant strength degradation of hygrothermal aged CFRP and its weibull analysis

The strength degradation of the composite material due to hygrothermal ageing is investigated with statistical significance. study aims report effect on moments material. Quasi-static tensile, compressive and flexure tests were performed a significant number samples by following ASTM standards. moisture absorption behaviour test specimens was modelled using Fick diffusion model. A observed ageing, while tensile also degraded appreciably. In moist environment, identified as critical property for marine structure. Further, Weibull analysis dry aged data two three-parameter statistics, distribution parameters compared both cases, which revealed that scatter in reduced ageing.
