This invention deals with composite articles of predetermined contour and with methods for their manufacture. The basic method involves providing a plurality of plies of a consolidated monotape, with each of the plies being precontoured in terms of size and degree of twist such that upon stacking the plies together, the plies provide a composite article of predetermined contour. The plies are stacked in predetermined relationship and then diffusion bonded together under heat and pressure to provide a complex shape such as a turbine engine blade to within close tolerances. |
