1. A method of manufacturing a combined material honeycomb core, the method comprising:
printing adhesive lines onto a sheet of a metallic material and a sheet of a meta-aramid material;
cutting the sheet of the metallic material and the sheet of the meta-aramid material into portions;
stacking the portions to form a stack comprising alternating layers of adjacent sheets of the metallic material and the meta-aramid material;
curing the adhesive in the stack to form an adhered stack; and
forming, by expanding the adhered stack, the combined material honeycomb core.
