Abstract (EN): The use of adhesive to bond composites in vehicles continues to increase. Due to hygrothermal conditions, both adhesive and composite properties can be altered, making the mechanical behavior of a joint unpredictable. The novelty of this work is the assessment of the behavior of joints manufactured using composite and aluminum substrates tested under quasi-static and impact conditions in the following states: unaged, hygrothermally aged, and dried after hygrothermal aging. A significant reduction of failure load was registered for composite joints (quasi-static and impact) after hygrothermal aging. Joints dried after aging achieved a recovery in the failure load of quasi-static tests.
