Claims25
A combined material honeycomb core comprising:
- a plurality of cells formed of multiple materials and regularly arranged in an array, the multiple materials comprising a first metallic material and either a non-metallic material or a second metallic material different from the first metallic material.
A structural panel with a combined material honeycomb core comprising:
- the combined material honeycomb core comprising a plurality of cells formed of multiple materials, the multiple materials comprising a first metallic material and either a non-metallic material or a second metallic material different from the first metallic material;
- a first facesheet adhered to a first face of the combined material honeycomb core;
- and
- a second facesheet adhered to a second face of the combined material honeycomb core.
A method of manufacturing a combined material honeycomb core, the method comprising:
- printing adhesive lines onto a sheet of a first material and a sheet of a second material, the second material different from the first material;
- cutting the sheet of the first material and the sheet of the second material into portions;
- stacking the portions to form a stack comprising the first material and the second material;
- curing the adhesive in the stack to form an adhered stack;
- and
- expanding the adhered stack to form the combined material honeycomb core.
A method of manufacturing a combined material honeycomb core, the method comprising:
- corrugating a plurality of sheets of a first material to form a first plurality of sheets of corrugated material;
- corrugating a plurality of sheets of a second material to form a second plurality of sheets of corrugated material;
- adhering the first plurality of sheets of corrugated material and the second plurality of sheets of corrugated material to form a honeycomb having an array of cells;
- and
- curing the adhesive joining the array of cells of the honeycomb to form the combined material honeycomb core.
