The invention relates to a device for the infiltration of fibrous material with resin for the production of a fiber composite component, comprising a mold tool with a cavity enclosed by at least two tool parts, wherein the mold tool is designed for a relative movement of the at least two tool parts, in such a manner that space can be provided inside the cavity, in a first tool position, to hold the fibrous material, and additional space can be provided to accommodate resin, and the size of the cavity can then be reduced by a movement of the mold tool from the first tool position into a second tool position. According to the invention, a flow promoter is included in the cavity, comprising at least one first layer and one second layer, connected to each other in an edge region of the flow promoter to enclose a flow space, wherein the first layer is impermeable to resin while the second layer provides an outlet for guiding resin out of the flow space and into the fibrous material, and wherein the flow space of the flow promoter is filled with resin and/or the flow promoter has an inlet for conveying resin into the flow space. The invention further relates to a corresponding infiltration process and to a use of the device and/or the method.
