Abstract

Accurately predicting the hygroscopic behavior of composite materials is of great significance for the reliability design and life assessment of composite products. In this paper, a method was proposed for mesoscopic modeling and simulation of the hygroscopic behavior of composites based on fiber arrangement image features. Benefiting from the method the problem was solved that the classical model cannot take into account the influence of fiber arrangement mode on moisture absorption rate. The distribution laws were discussed on moisture absorption rate at different moments and different paths, and the differences were compared between the fiber order-arrangement and disorder-arrangement models. The simulation results showed that the obstruction of water molecule diffusion was more severe in the disorder-arrangement model established from the fiber arrangement images, and the moisture absorption rate of the composite was lower than that of the order-arrangement model. Finally, the accuracy of the disorder-arrangement model was verified by two groups of hygroscopic experiments at temperatures of 40°C and 80°C, respectively. The prediction accuracy of the model for the moisture absorption curve reached more than 0.92.
