    Abstract: A pre-form and a method of preparing pre-forms are provided, The pre-forms comprise a resin and at least two layers of oriented fibre tows. The pre-forms comprise fibre tows instead of the traditional prepregs to enhance rearranging of resin and/or fibres during subsequent processing as well as provide greater freedom, a price reduction and/or a reduction of waste. The pre-forms may be formed three-dimensionally to enhance coupling to further pre-forms or other structures and/or to enhance shaping of the pre-form to a final three-dimensional shape. The method of preparation of pre-forms involves providing an adhesive between layers of fibres and providing a resin in contact with at least one of the layers of fibres. The resin Is preferably provided in a non-continuous layer to allow for removal of gas at least partially in a direction orthogonal to the layers of resin. The pre-forms are suitable for preparation of composite structures like for example spars for wind turbine blades.

    Abstract: A wind turbine blade comprising at least two wind turbine blade sections connected in a blade connection joint, where each blade section at their connection end comprises a number of corresponding dentations arranged to interconnect across the blade connection joint. One of the blade sections comprises a spar cap structure and a connecting part with a first end joined to the spar cap structure and an opposite second end positioned at the blade section connection end and comprising a number of the dentations. The connecting part further comprises a number of sheets which are interleaved with the fibre-reinforced layers of the spar cap structure in an overlapping zone thereby joining the spar cap structure and the connecting part. The invention further relates to a method for preparing a wind turbine blade section as mentioned above. The invention also relates to a method of preparing a sheet for a connecting part with a number of dentations at one end, which method involves cutting and rolling a number of unidirectional prepreg sheets to form fingers, placing in an open mould the fingers next to each other and partially apart such as to form the dentations, closing the mould, and fully or partially curing the sheet.

    Abstract: A method of transporting a blade for a wind turbine generator, includes attaching a blade root support frame to a root flange of the blade and attaching a blade spanwise support frame to a spanwise portion of the blade, connecting a first wheel base to the spanwise support frame, and connecting a transport unit to the root support frame. In another aspect, the blades may be stacked by use of the support frames without use of further equipment.

    Abstract translation: 本发明的一个方面涉及一种运输用于风力涡轮发电机的叶片的方法，所述方法包括将叶片根部支撑框架附接到叶片的根部凸缘并且将叶片翼展方向支撑框架连接到叶片的翼展方向部分 将第一轮基座连接到翼展支撑框架上，以及将运输单元连接到根部支撑框架上，其中运输单元包括承载结构和具有至少一个轴和两个车轮的第二轮底座，并且其中运输单元 在连接到根支撑框架之前，移动到叶片根部的部分下方的位置，并且其中第二轮基座在叶片下方，并且承载结构位于根部支撑框架的下方。 当运输单元移动到叶片下方的位置时，使得第二轮底座位于叶片下方，并且承载结构位于根部支撑框架的下方，来自叶片根部的负载分布在卡车或拖拉机之间 ，用于运输，第二轮底座降低了卡车或拖拉机的车轴压力。 此外，由于承载结构位于根部支撑框架的下方，所以仅可以从传送单元施加垂直载荷，使得与已知技术相比，施加在叶片上的力和扭矩显着降低。 第二方面涉及通过使用支撑框架而不使用其他设备来堆叠叶片。
