Benefits of technology
The present invention relates to a component for a gas turbine engine, which includes a continuous fiber blade and a platform. The continuous fiber blade and platform are coupled together to form a monolithic composite body. The invention also includes a method of forming the monolithic composite component by molding a continuous fiber thermoplastic composite into the continuous fiber blade and platform, and coupling them together. The technical effects of the invention include improved performance and durability of the gas turbine engine, reduced weight and cost, and improved manufacturing process.
Problems solved by technology
However, such airfoil-platform assemblies require additional process steps in order to couple the airfoils and platforms together, such as secondary bonding or fastening.
Further, such sealing may include leaks that reduce the efficiency of the gas turbine engine.

Abstract
A component for a gas turbine engine. The component includes a continuous fiber blade including an airfoil extending radially between a root and a tip and a blade attachment feature positioned at or adjacent to the root. The component further includes a platform coupled to the root of the continuous fiber blade. The platform includes a plurality of chopped fibers. Additionally, the component includes a thermoplastic polymer contained in both the continuous fiber blade and the platform. Moreover, the continuous fiber blade and platform are coupled together such that the continuous fiber blade and platform form a monolithic composite body.
Description
FIELD[0001]The present subject matter relates generally to monolithic composite components and, more particularly, to monolithic composite blades and platforms for gas turbine engines.BACKGROUND[0002]A gas turbine engine generally includes a fan and a core arranged in flow communication with one another. Additionally, the core of the gas turbine engine generally includes, in serial flow order, a compressor section, a combustion section, a turbine section, and an exhaust section. In operation, air is provided from the fan to an inlet of the compressor section where one or more axial compressors progressively compress the air until it reaches the combustion section. Fuel is mixed with the compressed air and burned within the combustion section to provide combustion gases. The combustion gases are routed from the combustion section to the turbine section. The flow of combustion gases through the turbine section drives the turbine section and is then routed through the exhaust section, ...
