ABSTRACT:
Rocket exit cones, and similar components are produced by weaving graphite fibers into fabric and wrapping a continuous length of the woven fabric over a rotating wind up form having a non-linear shape as the fabric leaves the loom. A compensator system is provided to accommodate for the varying distances the fabric must travel from the loom to the non-linear wind up form. During wrapping, the wind up form may be traversed for a short distance across the weaving loom to produce a differential wall thickness between the cylinder portion and the conical portion of the cone. In addition, the traverse motion enables the proper curvature to be imparted to the interface between the cylinder and conical portions of the exit cone.
The built fabric has a controlled shape, which is adapted for resin-impregnation and curing. The cured structure has sufficient integrity that permits machining of the conical portion to a uniform thickness or to a tapered thin wall.
