Resumen

This research investigates the post-impact behaviour of composite fuselage panels subjected to multisite low-velocity impacts. Large curved stiffened panels (1.2m x 0.8m, with composite skins/stiffenersand aluminum frames) of two different skin thicknesses were subjected to sequential drop-weightimpacts at locations previously determined to be critical in finite element (FE) simulations. Afterassessment of the impact damage each panel was tested in compression. High speed video, strain gauges,Digital Image Correlation and acoustic emission were used to monitor the failure development and toprovide data for comparison with the FE simulations. The FE models, which were based on amesomechanical approach, showed a good agreement with both the impact damage and the subsequentcompression performance.
