Method of making composite fan blade

摘要

A method for designing a composite airfoil (10), comprises designing a mold (32) having an inner surface (32i) that defines a surface profile of the airfoil, defining a preliminary core surface of a woven core (30), wherein the preliminary core surface is offset from the inner surface of the mold (32i) by a specified percentage, filling the space between the mold (32) and the preliminary core surface with a plurality of plies (26) and assembling the woven core (30) and the plurality of plies (26) in the mold (32) and curing to form the composite airfoil (10).
