ABSTRACT:
The invention is a method for the manufacture of hollow bodies, particularly pipes, from fabric reinforced resin by forming a coil of fabric impregnated with resin, which is dried, preheated, and introduced into a preheated mold. The coil is pressed axially into the mold between a preheated borer defining the interior shape of the pipe, and a sleeve, and the resin impregnated in the fabric is polymerized. The product is useful in the manufacture of nozzles for missiles or the like.
