Abstract: A method for fabricating a member in a resin-infusion-based casting process, in which at least one component forming the member is infused with a resin, including the steps: Providing a mold, the at least one component, the resin, at least one measurement device and at least one sensing device, wherein the sensing device has at least one property which changes measurably with temperature and/or when the sensing device comes into contact with the resin, attaching the at least one sensing device to an inner surface of the mold and/or to the component, arranging the component inside the mold, providing the resin to at least one inlet of the mold, and wirelessly measuring and evaluating the property of the sensing device with the measurement device for monitoring a temperature and/or a distribution of the resin in the mold and/or in the component, is provided.

Abstract: A method for manufacturing a wind turbine blade including: arranging an upper mold on a lower wherein a dry fiber lay-up is arranged in the upper mold or in the upper mold and the lower mold, applying vacuum to a space between the upper and lower molds, and infusing the dry fiber lay-up in the upper and/or lower molds with resin through at least one upper resin inlet arranged at an upper portion of the upper mold. Having the at least one upper resin inlet of the upper mold improves the vacuum-assisted resin infusion. Resin provided through the at least one upper resin inlet has to be raised by a smaller height to reach the top of the mold. A resin flow of the resin provided through the at least one upper resin inlet is supported in a downward direction by the gravitational force.

Abstract: A method for manufacturing a wind turbine blade, includes the steps of: arranging an upper mould including a pre-casted fibre lay-up on a lower mould comprising a dry fibre lay-up and a mould core, applying vacuum to a space between the upper and lower moulds and the mould core, infusing at least the dry fibre lay-up and a connection region between the dry fibre lay-up and the pre-casted fibre lay-up with a resin, and curing the resin. By having the pre-casted fibre lay-up in the upper mould, the packing and positioning of dry composite materials on top of the mould core is avoided.

Abstract: A device for absorbing heat generated by curing of a curable matrix material, particularly heat generated by curing of a curable matrix material embedding a textile structure including a number of reinforcing fibers is provided. The device includes at least one envelope element defining at least one inner volume, and at least one thermally conductive heat absorbing element disposed within the at least one inner volume of the at least one envelope element. In a further embodiment, the at least one envelope element may be built of or include at least one non-adhering material which does not adhere to the curable or cured matrix material.

Abstract: A mold and method for vacuum assisted resin transfer molding of a fiber reinforced laminated structure are provided. The mold includes a first mold part and a second mold part. The first mold part defines a negative impression of the laminated structure, being structurally stable and forming a support for fiber reinforcement layers of the laminated structure. The second mold part connectable to the first mold part for closing the mold and defines together with the first mold part an enclosed space which can be evacuated. The mold further includes a flow duct for guiding a liquid polymer which is formed as a recess in the first mold part and/or a recess in the second mold part that is open towards the enclosed space and extends along a section of the periphery of the first mold part and/or the second mold part.

Abstract: A method for manufacturing of a fiber reinforced laminate is provided. A part of the laminate is build up to a determined thickness. A layer of wrinkle-preventing material is placed on top of the partially completed laminate. The layer of wrinkle-preventing material has a greater stiffness than the stiffness of a layer of similar thickness of the uncured laminate. Further on a new part of the laminate is build up to a determined thickness. In case the thickness of the laminate built up is not as large as a desired thickness of the completed laminate, the placing of the layer and the building of a new part of laminate is repeated until the thickness of the laminate built up is equal to the desired thickness of the completed laminate.
