Abstract

The paper deals with the aluminum honeycomb that is very successfully used as applications in the transport industry and engineering production. Based upon its ability to absorb the large amount of energy, aluminum honeycomb has also found its utilization as the kinetic energy absorber. At low weight it has quite high compressive resistance and bending stiffness. The focus of this paper was to determine material behavior at impact loading and that is why the whole experiment was carried out on the special device (drop weight tester – drop tower), which makes possible to define magnitude of impact rate on the testing sample. As an observed factor there was magnitude of force and strain arising from the impact test. Based upon these values is possible to determine magnitude of absorbed energy by the honeycomb sample. Tests were performed by means of the visual analysis on the particular samples and by the quantitatively expression of measured data as graphs.
