Crush response of CFRP square tube filled with aluminum ...
Aug 01, 2016· Under crushing, except for the cell buckling, elastic and shear effects within the aluminum honeycomb, the inward CFRP fronds continuously extruded the aluminum honeycomb and increased the friction between the tube and honeycomb, providing other sources of energy absorption and resulting in a significant interspace between the tube wall and the compressed honeycomb (the area in Fig. 10b), .
