A fiber-reinforced component for use in a gas turbine engine, the fiber-reinforced component comprising:
- a first braided fiber sleeve forming a cooling channel;
- a plurality of fiber plies enclosing the first braided fiber sleeve, the plurality of fiber plies forming first and second walls separated by the first braided fiber sleeve;
- and
- a matrix material between fibers of the braided fiber sleeve and the plurality of fiber plies.
A method for manufacturing a fiber-reinforced component with integral fiber-formed cooling channels for use in a gas turbine engine, the method comprising:
- forming a first braided fiber sleeve;
- consolidating the first braided fiber sleeve to form a cooling channel of a desired shape;
- enclosing the first braided fiber sleeve with a plurality of fiber plies to form a fiber preform of a component with internal cooling provided by the cooling channel;
- and
- densifying the fiber preform.
