1. A method of forming a monolithic composite component for a gas turbine engine, the method comprising:
molding a continuous fiber thermoplastic composite including a thermoplastic polymer into a consolidated continuous fiber blade including an airfoil extending radially outward from a root to a tip and a blade attachment feature positioned at or adjacent to the root;
forming a plurality of chopped fibers into a consolidated platform containing the thermoplastic polymer; and
coupling the consolidated platform to the root of the consolidated continuous fiber blade in an injection molding process with the thermoplastic polymer such that the consolidated platform and the consolidated continuous fiber blade form the monolithic composite component.
