Claim 0:
1. A method for repairing a crack in a metal structure, the method comprising:
adhesively bonding a second fiber reinforced metal matrix composite tape layer to a first fiber reinforced metal matrix composite tape layer to form a patch, wherein the first fiber reinforced metal matrix composite tape layer comprises two or more fiber reinforced metal matrix composite tapes positioned adjacent to one another, wherein the two or more fiber reinforced metal matrix composite tapes comprise generally continuous fibers embedded in a metal matrix along the length of the tape, and wherein the second fiber reinforced metal matrix composite tape layer is positioned at an angle relative to the first fiber reinforced metal matrix composite tape layer;
positioning the patch over a crack in a metal structure such that at least one of the first fiber reinforced metal matrix composite tape layer and the second fiber reinforced metal matrix composite tape layer is oriented at an angle relative to the length of the crack; and
bonding the patch across the crack in the metal structure.
