Abstract
A method for manufacturing a ring-shaped frame made from composite material includes slipping at least one tubular casing of dry fibers over an assembly having at least two coaxial sub-assemblies axially movable relative to one another and between which a peripheral groove is defined. The assembly is disposed in the general plane of the frame. A portion of the tubular casing is forced into the groove and the two sub-assemblies are tightened so as to hold a portion of the tubular casing in the groove. Two parts of the casing that are outside the groove are coupled, and the obtained coupling is folded onto one of the two sub-assemblies in order to obtain a preform of dry fibers. The preform is solidified by polymerization.
