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

technical field [0001] The subject matter relates generally to integral composite components, and more particularly, to integral composite blades and platforms for gas turbine engines. Background technique [0002] A gas turbine engine typically includes a fan and a core arranged in flow communication with each other. Additionally, the core of a gas turbine engine typically includes a compressor section, a combustion section, a turbine section and an exhaust section in series flow order. In operation, air is supplied from a fan to the 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 compressed air and combusted in the combustion section to provide combustion gases. Combustion gases are channeled from the combustion section to the turbine section. The flow of combustion gases through the turbine section drives the turbine section and is then channeled through the e...
