摘要
Abstract
In this paper,the mechanical properties of steel and carbon fiber composite bonded by RN136N/HN136N two-component adhesive at 10～90℃were studied.Firstly,the mechanical behavior of the interface was simulated based on the cohesive force model.Secondly,the tensile shear test of carbon fiber composite and steel sin-gle bond sample was carried out at different temperatures.The failure mode and ultimate bearing capacity of the in-terface were studied.The results show that the failure mode of the sample has a great correlation with the tempera-ture.The ultimate bearing capacity of the sample is the highest at 30℃,and the ultimate bearing capacity and in-terface bond stiffness increase first and then decrease with the increase of temperature.The simulated ultimate bear-ing capacity is in good agreement with the experimental results.It is also found that the overall stress distribution of the joint is more uniform under low stress conditions.At higher stress levels,the middle of the joint will bear larger tensile stress and the two sides will bear larger shear stress.关键词
