Experimental study on crashworthiness of empty/aluminum foam/honeycomb-filled CFRP tubes

Thin-walled structures have been more and more extensively used as energy absorbing components in industry. It however remains challenging to decide best possible structural configurations. This paper compares the crashworthiness of empty circular CFRP (Carbon Fiber Reinforced Plastics) with CFRP/aluminum/steel tubes filled with aluminum foam or aluminum honeycomb under axial quasi-static crushing. The effects of the following factors on...
