Abstract: 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.

Abstract: A method for producing a component made of fibre-reinforced plastic by impregnating a fibre mould-blank (11) with a liquid impregnating material (10), includes at least the following steps: a) placing the fibre mould-blank (11) into a cavity (2) of a mould tool (1) while generating a temporary free space (9) between the fibre mould-blank (11) and at least one interior surface (19) of the mould tool (1); b) feeding the impregnating material (10) into this free space (9); c) closing the free space (9) by narrowing the mould tool (1) so that the impregnating material (10) is displaced from the free space (9) into the fibre mould-blank (11). It is further developed in that the mould tool (1) is gradually subjected to locally different forces (F1; F2; F3; . . . Fn, Fa; Fb; Fc) which locally cause the free space (9) to be closed. A mould tool (1) is also described.
