Abstract:Compression-after-impact tests were used to investigate the impact resistance of composite panel with hat-stiffener filled with foam via good energy absorption. The low-speed impact tests were conducted on three different locations, and then fringe projection profilometry was used to measure the full-field deflection of composite panels during compression. The experimental results show that local buckling occurs during compression of the free-impacted panels, and material compression damage of the impacted panels is caused by impact damage. The residual compressive strength of the stiffened panels is different because of damage of the stiffened panels at different impact locations. Finally, finite element simulation was performed to analyze the damage propagation in the compression-after-impact and the effect on the ultimate failure. The strain history, full-field deflection and numerical simulation results are of reference significance for the impact resistance design of hat-stiffened composite panels.
