This is a study of the hygrothermal behavior of the polyester/glass fiber composite material. The composite material is exposed on a lateral face to different humidity velocity under different temperatures. The kinetics of water absorption follows the Fick’s second law. The water concentration is higher on the surface of the material and it decreases continuously toward the core of the material. The increase of the humidity velocity induced a rise of the diffusion coefficient (D) and the amount of absorbed humidity at the saturation (Mm). Also, the augmentation of the temperature facilities the diffusion process. The fall of the absorption curve is due to the propagation of cracks in the material and the detachment of certain molecular chains. The finite-element software ‘‘Abaqus’’ is used to simulate the humidity diffusion through the composite material. The comparison between the experimental and numerical results shows that the model can predict the hygrothermal behavior of the polyester/glass fiber composite.
