| 摘要 |
The present invention relates to a method of manufacturing a laminated composite part from a number of layers of resin-preimpregnated fibres (1) which are placed on a moulding surface (2). At least one breather layer (5) is then placed over at least a part of the layers of resin-preimpregnated fibres (1). The breather layer (5) has a structure comprising at least one strand or string (9) arranged in a repeated pattern in order to provide a network of interconnected channels (11), said channels (11) extending in at least two non-parallel directions within the breather layer (5) and having a cross sectional area which is at least corresponding to a thickness of the strand or string (9). An airtight and flexible enclosure (6) is provided over the layers of resin-preimpregnated fibres (1) and the breather layer (1), air present in the enclosure (8) is evacuated, and the layers of resin-preimpregnated fibres (1) are heated to cause a decrease in viscosity of the preimpregnating resin to cause a flow of resin in a direction substantially perpendicular to the layers of resin-preimpregnated fibres (1) and towards the breather layer (5) for a predefined period of time. The present invention furthermore relates to a wind turbine blade manufactured by such a method. |
