Claim:
A method for vacuum assisted resin transfer moulding of a fibre reinforced laminated structure, comprising: providing a for vacuum assisted resin transfer moulding of a fibre reinforced laminated structure, comprising: a first mould part defines a negative impression of the fibre reinforced laminated structure, the first mould part structurally stable and forms a support for fibre reinforcement layers of the fibre reinforced laminated structure, a second mould part connectable to the first mould part in order to close the mould and together with the first mould part defines an enclosed space to be evacuated, a flow duct that guides a liquid polymer, the flow duct is open towards the enclosed space and is formed as a recess in the first mould part extending along a section of a periphery of the first mould part and/or a formed as a recess in the second mould part and extending along a section of the periphery of the first mould part; and a spacer element forming a portion of the flow duct, the spacer element configured to prevent the second mould part from entering the flow duct after the enclosed space has been evacuated, keeping the flow duct free of any material until the resin is injected; and injecting the resin such that the resin runs in the flow duct from an inlet port to a far end of the mould.
