An instrumented test procedure for low energy impact tolerance of thin skin sandwich panels was developed. Damage modes of this test were shown to correlate on a one-to-one basis with actual falling ball tests. Basic parameters of core density, cell size, skin thickness, and fiber orientation were examined and results useful to designing of sandwich panels are discussed. Author
