    Abstract

    An investigation was conducted to evaluate the feasibility of fabricating full-scale fan blades from superhybrid composites (SHC) for use in large commercial gas turbine engines. The type of blade construction selected was a metal-spar/SHC-shell configuration, in which the outer shell was adhesively bonded to a short, internal, titanium spar. This report describes various aspects of blade fabrication, inspection, and quality assurance procedures developed in the investigation. Conclusions from this investigation indicate that the SHC concept is feasible for the fabrication of prototype, full-scale, metal-spar/SHC-shell fan blades that have good structural properties and meet dimensional requirements.
