Fabrication and mechanical behaviors of an all-composite sandwich structure with a hexagon honeycomb core based on the tailor-folding approach

The tailor-folding method is proposed to make an all-composite sandwich panel with a carbon fiber reinforced polymer (CFRP) hexagon honeycomb core. Using this method, a CFRP honeycomb core with continuous fibers is fabricated automatically from a continuous plain woven prepreg to reinforce the constraints between adjacent cell walls. The analytical expressions were derived for predicting the stiffness and strength of the CFRP hexagon honeycomb...
