    Abstract
  • In order to provide a reference for crash safety of vehicle adhesive structure, the BFRP was selected to make single lap joints. According to the service environment of vehicle, the joints were aged for 0, 5, 10 and 15 d in two environments with the temperatures and humidities of 80 ℃/30%(GWCS) and 80 ℃/95%(GWGS), respectively. The change rules of failure load and failure mode with time were tested by using the quasi-static tensile test. The glass transition temperatures of BFRP and adhesive before and after aging were analyzed by using the differential scanning calorimetry. The transverse impact tests with the impact energies of 0, 20, 40 and 60 J were carried out for the joints which were unaged or aged for 15 d. The variation rules of energy absorption, the maximum impact load and the maximum deformation with the impact energy were analyzed, and the change rules of joint failure load and failure mode were also tested. Analysis result shows that after aging in the GWCS environment, the failure loads of joints decrease slightly, and the post-curing reaction of adhesive and the molecular chain fracture of BFRP occur, which makes the joints more prone to the matrix cracking or fiber tearing. In the GWGS environment, aging can obviously accelerate the degradation of joint performance, and easily cause hydrolysis and expansion of the interface between adhesive and BFRP. After 15 d of aging, the failure loads decrease by 54.99%, and the mixed failure of interface and cohesion occurs. After aging in the GWCS environment, the joints have good resistance to the impact load and deformation, and the failure loads change little after impact. After aging in the GWGS environment, the joint is obviously affected by the transverse impact, and its ability to bear the impact load and resist deformation is poor. After the impact of 60 J, the joint surface damages seriously, and the failure load decreases significantly, with the decrement rate of 58.71%. The mixed failure of interface and cohesion occurs, and the damage crack is obvious. It can be seen that in the process of vehicle service, the adhesive structure should avoid the effect of high-temperature and high-humidity environment, especially the influence of transverse impact on the aging adhesive structure.
