ABSTRACT OF THE DISCLOSURE
A high specific modulus shaft for a gas turbine
engine is constructed having a metal outer tube to trans-
mit the torque and a metal and high modulus filament com-
posite sleeve bonded to the tube's inner diameter. The
composite sleeve is fabricated and bonded to the inner
diameter of the tube by winding the composite composition
tape on a mandrel with the filaments axially aligned. The
mandrel is then inserted into a metal outer tube. The as-
sembly is encapsulated, evacuated and sealed and the man-
drel pressurized at a sufficient temperature to achieve
consolidation and diffusion bonding of the wound composite
to itself and the shaft inner diameter.
