Abstract

The energy-absorbing characteristics of aluminium honeycomb reinforced with CFRP tubes subjected to quasi-static compressive loading is studied herein. Crushing tests on individual CFRP tubes yielded specific energy absorption values as high as 110 kJ/kg. It was observed that the composite tubes efficiently absorbed large amounts of energy via a number of failure modes, similar to those observed in much larger tubes. Following this, between one and nine composite tubes were inserted into square blocks of aluminium honeycomb. Subsequent crushing tests on these tube-reinforced honeycomb structures resulted in SEA values of up 100 kJ/kg. This evidence suggests that tube-reinforced honeycombs offer significant potential for use in energy-absorbing structures.
