More attentions have been paid to the researches on the moisture absorption of polymer matrix com- posites. In this paper, the hygroscopic mechanisms of moisture absorption of polymer matrix composites are emphati- cally reviewed, simultaneously, processes of moisture absorption and diffusion curves are carefully analyzed. The in- fluences of external factors and material parameters on moisture absorption of polymer matrix composite, as well as property changes triggered by moisture absorption, are also described. Then, causes of these dissimilarities are detailedly analyzed. In the last part, the moisture absorption of natural plant fiber reinforced polymer composites is introduced.
