Abstract
A composite component such as a fan rear seal comprises a hub and a body of composite material which is molded over the outer periphery of the hub. The body is formed from a preform of fiber reinforcement impregnated with a resin, in a compression molding process. The body has an annular projection provided with a sealing surface. The sealing surface may comprise circumferential fins, or may be a surface of, for example, an abradable seal insert molded into the composite material of the body.
