“…The use of adhesive-bonding technology can reduce the weight of structural components, improve manufacturing efficiency, reduce manufacturing costs, and avoid stress concentration caused by drilling and structural damage to CFRP [ 8 ]. Therefore, bonded composite structural components are widely used in aircraft [ 9 ]. Research on composite bonding mainly involves the design and performances of adhesives [ 10 , 11 , 12 ], the mechanical behavior and properties of adhesive-bonded composite joints [ 13 , 14 , 15 ], analysis methods [ 4 , 16 ], and numerical simulations [ 17 , 18 , 19 ].…”

Bismaleimide (BMI) resin-based structural adhesives have excellent heat resistance, with important applications demonstrated in the bonding of high-temperature BMI composites. In this paper, we report an epoxy-modified BMI structural adhesive with excellent properties for bonding BMI-based CFRP. We prepared the BMI adhesive using epoxy-modified BMI as the matrix and PEK-C and core–shell polymers as synergistic tougheners. We found that the epoxy resins improve the process and bonding properties of BMI resin but slightly reduce thermal stability. PEK-C and core–shell polymers synergistically improve the toughness and bonding performances of the modified BMI adhesive system and allow the maintenance of heat resistance. The optimized BMI adhesive exhibits excellent heat resistance, with a high glass transition temperature of 208.6 °C and a high thermal degradation temperature of 425.4 °C. Most importantly, the optimized BMI adhesive exhibits satisfactory intrinsic bonding and thermal stability. It has a high shear strength of 32.0 MPa at room temperature and up to 17.9 MPa at 200 °C. The BMI adhesive-bonded composite joint has a high shear strength of 38.6 and 17.3 MPa at room temperature and 200 °C, respectively, indicating effective bonding and excellent heat resistance.
