Definitions
- Wind turbine blades are increasing in size particularly in length, the lengths of some blades now exceeds 50 metres and in some instance exceeds 70 metres. This increase in length requires greater strength which requires thicker blades made from larger stacks of multiple layers of composite fibre and resin reinforcement, it is preferred that the thickness be accomplished by increasing the number of layers rather than increasing the thickness of the individual layers. However as the number of layers increases it is increasingly difficult to get the desired surface finish and homogeneity throughout the thickness and along the length of the blade.
- resin preimpregnated fibrous reinforcement prepreg
- dry fibre layers are laid up in a mould and these are subsequently infused with a curable resin matrix using a vacuum assisted resin transfer moulding process (VARTM).
- a fifth moulding material in the form of a unidirectional laminate wherein the laminate comprises fibrous reinforcement in the form of unidirectional carbon fibres and a fabric on one or both sides of the carbon fibres, the fabric being stitched thereto, said fibrous reinforcement being impregnated with resin and cured.
- the fabric may comprise fibres in the warp direction and fibres in a weft direction, said weft direction being at 90° or at an angle between 30° to 85°, preferably between 60° to 80°.
- the fabric may be non-woven.
- the fabric may comprise a glassfiber.
- impregnated and unimpregnated tows may be co-located to form a single plane of fibrous reinforcement.
- the longitudinal axes of the impregnated and unimpregnated tows in a layer or sheet of the fibrous reinforcement may be parallel to one another and their axes may all be located in a single plane.
- the present invention is particularly concerned with providing a prepreg that can be based on a reactive epoxy resin that can be cured at a lower temperature with an acceptable moulding cycle time.
- Curing at a pressure close to atmospheric pressure can be achieved by the so-called vacuum bag technique. This involves placing the prepreg or prepreg stack in an air-tight bag and creating a vacuum on the inside of the bag. This has the effect that the prepreg stack experiences a consolidation pressure of up to atmospheric pressure, depending on the degree of vacuum applied.
- Figure 6 presents a microscopy cross section of lay-up 2 of Figure 1 ;
- Figures 8 and 9 show that the use of a cured laminate in combination with prepreg layers 3 in the stack produces a more regular and uniform surface even if a disturbance (wire (4) ) is present in the lay-up structure.
