Abstract
A composite sandwich panel includes a first composite part and a second composite part. A plurality of stiffeners extend between the first and second composite parts. A fiberglass composite perimeter edge closeout is positioned along one or more edges of the first and second composite parts. The fiberglass composite perimeter edge closeout controls a magnetic flux to bond the first and second composite parts to the plurality of stiffeners.
Claims15
A composite sandwich panel comprising:
- a first composite part;
- a second composite part;
- a plurality of stiffeners extending between the first and second composite parts;
- and
- a fiberglass composite perimeter edge closeout positioned along one or more edges of the first and second composite parts, the fiberglass composite perimeter edge closeout having an angled body extending between a pair of planar ends such that the angled body is sloped from one end of the pair of planar ends to another end of the pair of planar ends, the pair of planar ends extending along a surface of the first and second composite parts, the fiberglass composite perimeter edge closeout configured to control a directional magnetic flux to inductively bond the first and second composite parts to the plurality of stiffeners and close open ends of and form edges between the bonded first and second composite parts as the directional magnetic flux is being directionally controlled to re-direct the directional magnetic flux within the composite sandwich panel where an energy field acts on a plurality of susceptor resin assemblies placed at co-bonding interface flange faces to weld the fiberglass composite perimeter edge closeout, the plurality of stiffeners, the first composite part, and the second composite part into an assembled single part structure.

A composite sandwich panel comprising:
- a first composite part;
- a second composite part;
- a fiberglass composite perimeter edge closeout positioned along one or more edges of the first and second composite parts, the fiberglass composite perimeter edge closeout comprising:
- a body formed from a material having dielectric properties to control a directional magnetic flux to inductively bond the first and second composite parts to the fiberglass composite perimeter edge closeout, the body being angled, and sized and shaped to form edges of the composite sandwich panel;
- and
- a pair of planar ends extending from the body, the body being angled between the pair of planar ends such that the body is sloped from one end of the pair planar ends to another end of the pair of planar ends, the pair of planar ends configured to abut edges of and extend along a surface of the composite sandwich panel and inductively bond thereto to close open ends of and form the edges between the bonded first and second composite parts as the directional magnetic flux is being directionally controlled to re-direct the directional magnetic flux within the composite sandwich panel where an energy field acts on a plurality of susceptor resin assemblies placed at co-bonding interface flange faces to weld the fiberglass composite perimeter edge closeout and the first and second composite parts into an assembled single part structure.
