Controlled circumferential impregnation device

摘要

A device for molding by impregnation of at least one reinforcing layer constituting a piece to be molded or at least one reinforcing layer covering a piece, with a resin in liquid form. The device includes a mold extending around the reinforcing layer by defining a resin circulation space, an end piece for supplying resin in the circulation space, an end piece for evacuating the surplus resin as well as elements for generating a flow of resin in the circulation space. The mold includes a flexible conduit and elements for mechanically deforming the flexible conduit to shape the circulation space according to the impregnation parameters.
