Claim 11:
12. A method of manufacturing a fan blade comprising:
shuffling plies in a fan blade prior to contacting the plies with one another such that they form interleaved plies; where interleaving comprises distributing wide plies within narrow plies and short plies within long plies in the fan blade; wherein the interleaving is defined as an actual intersection of a plurality of plies of different variable dimensions that extend in the chordwise direction with a another plurality of plies of different variable dimensions that extend in the spanwise direction such that their respective longitudinal axes intersect with one another at angles of 5 to 175 degrees; and
curing the interleaved plies to form the fan blade.
