^1^ TITLE; METHOD AND APPARATUS FOR PRODUCING FIBRE COMPOSITE W MOULDINGS BY MEANS OF VACUUM INFUSION ABSTRACT Apparatus and method of producing fibre composite mouldings by means of vacuum infusion and utilizing a mould with a mould cavity, a plurality of inlet chaimels (3, 21, 22) communicating with the mould cavity and a polymer source (7) with liquid polymer, a plurality of vacuum channels (2) communicating with the mould cavity and a vacuum source (10), where fibre material (14) is inserted into the mould cavity prior to the process of filling said mould, and where a negative pressure is generated in the vacuum channels (2) and thus in the mould cavity with the result that liquid polymer is drawn fi"om the polymer source (7) via the inlet channels (3, 21, 22) into the mould cavity. One or more of the inlet channels (3, ^k 21, 22) can also commimicate with a vacuum source, and/or one or more of the vacuum channels (2) can also commimicate with a polymer source (7). FIG. 2 14
