Method of manufacturing a composite fan blade with co-cured sheath, and corresponding fan blade

摘要

The invention concerns a method of forming a composite blade (10) having a sheath (17) on a portion of the blade by placing the dry composite blade (10) and sheath (17) in a mould (32), adding a resin, and curing the resin to integrally bond the blade (10) to the metal sheath (17). The portion of the blade having the sheath bonded thereto may be at least one of the leading edge (14), the tip (20) and the trailing edge (12) of the blade.
