STUDY ON SHEAR PROPERTIES OF

Abstract

Abstract: In this paper, room-temperature curing and high-toughness epoxy and acrylate structural adhesives were used to join the Carbon Fiber Reinforced Polymers (CFRP) and steel plates. The shear strength, failure mode and environmental durability of these two kinds of structural adhesives were analyzed. The results show that the shear strength of the high-toughness epoxy structural adhesive was 23.5 MPa after curing, and the failure modes were mainly cohesive failure as well as interface failure. And, the shear strength of the high-toughness acrylate structural adhesive was 12.83 MPa after curing, with the failure mode being dominated by interface failure. In addition, the paper also explored the effect of electrophoresis baking process on the shear strength and failure mode of two structural adhesives. The results show that the shear strength of the epoxy structural adhesive after electrophoresis was 7.28 MPa, which was 69% lower than that before electrophoresis, and the failure mode was cohesive failure of the adhesive layer. Besides, the strength of the acrylate structural adhesive was 15.65 MPa, which was 21.6% higher than that before electrophoresis. The failure modes were both cohesive failure and substrate failure. It could be seen that the electrophoretic baking process had different effects on the shear strength of different structural adhesives. When the CFRP parts need to be electrophoreled with the steel body, the acrylate structural adhesive can meet the requirement of shear strength.

Key words: room-temperature curing, structural adhesive, carbon fiber reinforced polymers, steel, shear properties
