Apparatus and method of producing fiber composite moldings by means of vacuum infusion applying a mold with a mold cavity, a plurality of inlet channels (3, 21, 22) communicating with the mold cavity and a polymer source (7) with liquid polymer, a plurality of vacuum channels (2) communicating with the mold cavity and a vacuum source (10), where fiber material (14) is inserted into the mold cavity prior to the process of filling said mold, and where a negative pressure is generated in the vacuum channels (2) and thus in the mold cavity with the result that liquid polymer is drawn from the polymer source (7) via the inlet channels (3, 21, 22) into the mold cavity. One or more of the inlet channels (3, 21, 22) can also communicate with a vacuum source, and/or one or more of the vacuum channels (2) can also communicate with a polymer source (7).
