Abstract

Moisture transfer parameters were evaluated for Hexcel CFRP, used in aerospace applications. The additive moisture transfer model was used to investigate the early stages of environmental degradation. After 6 month of outdoor exposure in warm tem-perate maritime climate initial stages of polymer degradation were discovered in surface layer less than 10 µm. Influence of CFRP degradation on the moisture transfer pa-rameters was evaluated.
