Abstract
Rocket exit cones, rocket motors, curved objects, and the like, are produced by weaving a fabric onto a non linear form and rotating the form to wind up the fabric as it is being woven. Compensation between the linear, flat shape of the fabric and a non linear shape of the wind up form is obtained by conforming the shape of the reed portion of the loom to the shape of the form, and by providing a constant and/or variable spacing between the reed elements. A uniformly wrapped, non linear shape is is produced by the process. Following wrapping, the fabric shape is impregnated with resin, and cured to a carbonized and/or graphitized state. Finally, the cured shape may be machined to its desired size and contour, having uniform properties.
