4. Conclusion: This study focuses on the comparison between the performance of brittle adhesives commonly used in the construction industry and ductile adhesive in CFRP/Steel double strap joints. The joints with ductile adhesive reached much significantly higher strengths than the ones with brittle adhesives. The DIC results reveal that the ductile adhesive promotes a more uniform distribution in CFRP/Steel joint than the brittle ones. 5. References: [1] A. Mohabeddine, J. A. F. O. Correia, P. A.
