An experimental study on the buffer characteristics of the honeycomb sandwich construction are carried on using the actual honeycomb-core and the enlarged model, and the following results are obtatined. (1) The characteristics of the actual honeycomb-core can be made clear by using the enlarged model. (2) The static ultimate compressive stresses and the mean crushing stresses agree approximately with the calculated values. (3) The dynamic ultimate compressive stresses convege on a value about 1.5 times larger than the static values with increase in the kinetic energy. (4) The dynamic mean crushing stresses are nearly equal with the static values. (5) The study has identified the improvement of the buffer characteristics of the core by the precrush.
