Three-dimensionally woven preform for a composite blade with spanwise weft yarns and method for manufacturing a composite blade

摘要

A composite blade (32) has a root (44) and a tip (42) in a spanwise direction and a leading edge (34) and a trailing edge (36) in a chordwise direction. The composite blade includes a three-dimensional woven preform (48) having weft yarns (54) and warp yarns (52). The weft yarns extend in the spanwise direction of the composite blade. The warp yarns interweave the weft yarns and extend in the chordwise direction of the blade.
