Abstract:
1. A method for producing a composite structure comprising fibre reinforced material by means of vacuum assisted resin transfer moulding, where fibre material is impregnated with liquid resin, the method comprising the steps of: a) providing a forming structure comprising a rigid mould part and a second mould part and having a longitudinal direction, and a transverse direction with a first side and a second side, b) placing the fibre material in the rigid mould part, c) sealing the second mould part against the rigid mould part to form a mould cavity, d) connecting a source of uncured fluid resin to at least one resin inlet communicating with the mould cavity, e) connecting at least one vacuum outlet communicating with the mould cavity, f) evacuating the interior of the forming structure through the at least one vacuum outlet, g) after completing step f), supplying uncured resin from the source of uncured resin to the mould cavity through the at least one resin inlet so as to fill the mould cavity with resin, and h) curing the resin in order to form the composite structure.
