Abstract
The paper focused on the moisture absorption and hygrothermal degradation of composite laminates repaired via double scarf method. Experimental works were carried out on double scarf-repaired composite laminates to elucidate the effect of hygrothermal aging on the failure strength and failure mode. Finite element models were established to study the moisture distribution in the composite laminates and adhesive layer. And a progressive damage model considering the moisture gradient was subsequently proposed to predict the strength and analyze the damage mechanism. At last, the effects of overlap patch and moisture content on the failure strength were discussed.
