Abstract
A caul is used in an autoclave process for consolidating a composite, multi-ply, gas turbine fan blade preform having first and second opposite sides and a varying thickness therebetween. The caul includes a body having fibers situated in a matrix. The caul is complementary in shape to the preform first side and has a bending flexibility varying over the body for correspondingly varying consolidation of the preform. The second side of the preform is shaped by a bottom mold in the autoclave chamber.
