METHOD AND APPARATUS FOR PRODUCING FIBRE COMPOSITE MOULDINGS BY MEANS OF VACUUM INFUSION

摘要

Apparatus and method of producing fibre composite mouldings by means of vacuuminfusion applying a mould with a mould cavity, a plurality of inlet channels(3, 21, 22) communicating with the mould cavity and a polymer source (7) withliquid polymer, a plurality of vacuum channels (2) communicating with themould cavity and a vacuum source (10), where fibre material (14) is insertedinto the mould cavity prior to the process of filling said mould, and where anegative pressure is generated in the vacuum channels (2) and thus in themould cavity with the result that liquid polymer is drawn from the polymersource (7) via the inlet channels (3, 21, 22) into the mould cavity. One ormore of the inlet channels (3, 21, 22) can also communicate with a vacuumsource, and/or one or more of the vacuum channels (2) can also communicatewith a polymer source (7).
