%X Under the cyclic loading, the important damage characteristic of fibre-reinforced polymeric matrix composites is the damage behaviour depending on both the material microstructure and the chemical effect. Focusing on this characteristic, mechano-chemical molecular chains model for studying fatigue damage was established. The fractions of broken molecular chains in matrix and on interface were introduced respectively to describe the matrix-dominated damage or interface-dominated damage mechamism. The mechano-chemical effect was included in molecular scale and the influence of microstructure on fatigue process was considered. The relations between residual strength and mechanical properties, microstructure parameters, physical chemistry parameters were analyzed as well. Load-constant fatigue tests for composite material (SMC) were carried out, and the experimental results appeared good agreement with predicted values based on the proposed model.
