Abstract
A composite structure comprises stacked sets of laminated fiber reinforced resin plies and metal sheets. Edges of the resin plies and metal sheets are interleaved to form a composite-to-metal joint connecting the resin plies with the metal sheets.
Claims25
A metal structure exhibiting improved strain performance, comprising:
- at least a first metal laminate including a first plurality of metal sheets bonded together.
An integrated attachment fitting for a structure, comprising:
- a composite resin portion;
- a metal portion;
- and
- a composite-to-metal joint between the composite resin portion and the metal portion.
A fastener reinforcement for reinforcing an area of a multi-ply composite structure, comprising:
- a metal laminate including a plurality of metal sheets bonded together, the metal laminate having a through hole therein adapted to receive a fastener therein;
- and
- a composite-to-metal joint between the metal laminate and the composite structure.
A method of fabricating a composite structure, comprising:
- assembling at least a first stack of metal sheets;
- and
- laminating the first stack of metal sheets together by placing a layer of adhesive between each of the metal sheets.
A method of reinforcing an area of a composite laminate containing a fastener passing through the thickness of the composite laminate, comprising:
- integrating a multi-ply metal laminate into the area of the composite laminate to be reinforced;
- forming a through hole in the metal laminate adapted to receive the fastener therein.
A method of reinforcing an edge of a multi-ply fiber reinforced resin laminate, comprising:
- joining a metal laminate to the resin laminate along the edge of the resin laminate.
