Abstract
A method for fabricating a rotor blade includes fabricating a rotor blade that includes a dovetail and an airfoil coupled to the dovetail, the airfoil including a first side, a second side, and a plurality of openings extending therethrough, and weaving a composite material through the openings such that the airfoil has an aerodynamic profile that is substantially smooth from an airfoil leading edge to an airfoil trailing edge.

A method for fabricating a rotor blade for a gas turbine engine comprises:
- fabricating a rotor blade that includes a dovetail and an airfoil coupled to the dovetail, the airfoil including a first side, a second side, and a plurality of openings extending therethrough;
- and
- weaving a composite material through the openings such that the airfoil has an aerodynamic profile that is substantially smooth from an airfoil leading edge to an airfoil trailing edge.
A rotor blade for a gas turbine engine, said rotor blade comprising:
- a dovetail;
- an airfoil coupled to said dovetail, said airfoil comprising a first side, a second side, and a plurality of openings extending therethrough;
- and
- a composite material woven through said openings such that said airfoil has an aerodynamic profile that is substantially smooth from an airfoil leading edge to an airfoil trailing edge.
