Claim 17:
18. A method of making a blade comprising:
laying a plurality of first composite fiber plies on the blade; and
laying a plurality of second composite fiber plies, the plurality of second composite fiber plies including a plurality of spanwise fiber plies that decrease in both a chordwise length and a spanwise length monotonically from a surface of the blade inwardly, the plurality of second composite fiber plies further including a plurality of non-spanwise fiber plies that do not monotonically decrease or increase in either a chordwise length or a spanwise length from the surface of the blade inwardly, in combination with the plurality of the first composite fiber plies to make ends of the second composite fiber plies be staggered such that interlock between the first composite fiber plies and the second composite fiber plies is formed in a region where the second composite fiber plies end and meet with the first composite fiber plies.
