Abstract
A platform for a turbofan gas turbine engine that does not limit the rotation capability of adjacent fan blades in the event one of the fan blades is impacted by a foreign object. The platform includes a structural body portion and an integrally formed flowpath surface portion. The structural body portion has a contour that matches that of the adjacent fan blades. The flowpath surface portion defines a pair of wings that extend laterally beyond the structural body portion. The wings are frangible so as to break off if an adjacent fan blade rotates in response to an ingestion event. The platform is made from a composite material using a resin transfer molding process.
