Abstract
In this paper based on the turbofan engine fan casing, the rectangular cross-section TC4 flyer high-speed impact carbon fiber/bismaleimide (CF/BMI) composite laminate was used to simulate the impact of failed blade fragments on the casing. Based on mechanical properties tests and equivalent mechanics theory, the mechanical properties parameters of laminates were obtained. The mesoscopic CF/BMI laminates model was built by TexGen. The Hashin failure criterion was implanted into the VUMAT subroutine. ABAQUS/Explicit was used to simulate the normal penetration and oblique penetration of ballistic impact experiments to obtain the strain time history curves, macroscopic damage process and mesoscopic damage morphology. The reliability of the numerical simulation method was verified by ballistic impact test. On this basis, the mechanical response and impact damage characteristics of flyer penetrating CF/BMI laminates under different impact velocities (260 m/s, 300 m/s), incident angles (45°, 60°, 90°) and flyer flight attitudes were studied. The damage characteristics of CF/BMI laminates under high-speed impact of flyer were obtained by combining the dynamic response analysis of two components of carbon fiber layer and bismaleimide resin in the laminates.
