Fatigue Crack Growth Behavior of Adhesively-Bonded Unidirectional and Woven CFRP/Aluminum Joints with Acylic Adhesive

Structural acrylic adhesives have been attracted special interest because theses can be cured at room temperature and bonded to oily substrates. To use adhesively joints more widely for structural use, it is necessary clarify fatigue crack propagation characteristics. In this study, growth rate was measured using unidirectional woven CFRP/aluminum double cantilever beam (DCB) with an adhesive. elucidate the difference of rates between adhesive CFRP adherends, finite element analysis conducted these joints, wherein Gurson's model applied layer. The differences elucidated from distributions void fraction in front tip both joints.
