| Summary: | The effect of low density filler material comprising polyurethane foam on the axial
crushing resistance of Nomex honeycomb under quasi-static compression conditions was analyzed.
Honeycombs with two different densities, two different heights and similar cell size, along with five
different densities of polyurethane foams were used in the research. A total of 14 unfilled Nomex
honeycombs, 15 polyurethane foams, and 39 foam-filled Nomex honeycombs were subjected to quasi-static compression loading. The crushing load and capability of foam-filled Nomex honeycomb structure in absorbing the energy were found to increase significantly since the cell walls of honeycomb were strengthened by the foam filler; the walls did not buckle at the very beginning of compression loading. The failure mechanism of the foam-filled honeycomb was analyzed and compared with the unfilled honeycomb. |
