A combined experimental and numerical study of compression-after-impact strength of honeycomb core sandwich composite panels is described. Barely-visible impact damage was induced using quasi-static indentation. Specimens consisted of 16-ply carbon-epoxy facesheets with an aluminum honeycomb core. The facesheet stacking sequence, core geometry and thickness were varied as was the indentor diameter to study the effect of these parameters on damage resistance and post-impact damage tolerance. Computational models of the quasi-static indentation and compression after impact are underway. Results to date compare the experimental and simulate indentations for 25.4 mm diameter indentors. Future work will include modeling the larger, 76.2 mm indentor as well as compression-after-impact.
