A scaleable technique of producing thick, hoop-wound composite rings by filament winding with epoxy resins continuously gelled and cured at high rates of radial material accretion is described. The temperature and radial accretion rates of the process must be well controlled in order to achieve a desired maximum distance between the continuously advancing gel front and the continuously growing outer surface of the part. The in-situ gelled and cured rings made of carbon and glass fibers in this investigation are shown to have void contents and transverse properties that are comparable to conventionally wound composites. Radial rates of material accretion of up to 20.3 cm/hr (8 in/hr) were achieved with no visually apparent fiber buckling or waviness.
