Abstract
In the embodiment described in the specification, a high temperature wet filament winding arrangement has a wet bath containing a resin at a temperature above 500.degree. F. and filaments drawn from a spool rack are passed through the wet bath and then through a heated comb which maintains the temperature of the filaments above 500.degree. F., after which the filaments are passed through a heated passage controlled to maintain the temperature above 500.degree. F. A winding eye, also heated to maintain the filament temperature above 500.degree. F., directs the heated fibers onto a mandrel where they are wound in uniform layers into the form of a final product. A mandrel heater heats the mandrel to which the fibers are being applied so as to maintain a uniform temperature above 500.degree. F.
