    Abstract: Composite structures and methods of forming composite structures are provided. A composite structure as disclosed herein incorporates one or more composite structure components, such as composite panels (240A, 240B) and composite inserts (138). A composite panel is formed from one or more sheets of fiber reinforced thermoplastic material. Composite inserts can include one or more composite blocks or braided sleeves (138). A composite block (232) can be formed as a stacked or molded structure from trimmings or waste produced during the formation of the composite structures. A braided sleeve (138) can include a seamless, woven sleeve formed of reinforcing fibers and thermoplastic threads. In a completed composite structure, composite inserts are at least partially disposed within a volume defined by surfaces of composite panels. The various composite structures and inserts can be given a final shape and can be fused to one another in a molding and fusing step.

    Abstract: The present invention relates to a pre-impregnated fibre sheet (20a, 20b) extending in a longitudinal direction and in a transverse direction and comprising a first fibre layer (21) forming part of an upper surface of the pre-impregnated fibre sheet and a second fibre layer (22) forming part of a lower surface of the pre-impregnated fibre sheet, wherein the first fibre layer is pre-impregnated with an adhesion promotor. The present invention further relates to methods of manufacturing a blade shell member or wind turbine blade comprising a pre-manufactured spar cap (100) and a number of pre- impregnated fibre sheets (20a, 20b) arranged to obtain an improved adherence between the blade shell (80) and pre-manufactured spar cap, particularly when the pre-manufactured spar cap is resin infused with vinyl ester or epoxy resin and the blade mould is resin infused with polyester.

    Abstract: Dargestellt und beschrieben ist ein Verfahren zur Herstellung von Formteilen, insbesondere aus Faserverbund-Werkstoff. Um die Belastung der Membran zu reduzieren, wird vorgeschlagen, dass die Membran (4, 4A', 4B') an der Dichtung (16, 16') vorbeiführbar ist und dass in Schritt c) die M embran (4, 4A', 4B') aufgrund der Ausdehnungskraft (FA) wenigstens abschnittsweise an der Dichtung (16, 16') vorbeigefuhrt wird.

    Abstract: Apparatus for measuring an electrical property of a sheet of electrically conductive compressible material comprises a substrate of non-conductive material having a top surface on which a sheet may be placed, two electrodes on the top surface such that they define two edges of a rectangular space on the top surface, means for applying pressure to the top surface of the substrate such that the sheet is compressed, and means for measuring an electrical property of the sheet, attached to the electrodes. The means for applying pressure may be a means for creating a vacuum such as a vacuum pump. The electrically conductive compressible material may be layered with other materials before compression such that its electrical property is measured as part of a composite material.

    Abstract: The present invention relates to a method of manufacturing a fibre-reinforced spar cap (41) for a wind turbine. The method comprises the steps of providing a mould (62), and fastening a first guide member (64) and a second guide member (66) to the mould for providing a moulding cavity (68) in between the first and second guide members. A fibre material can be arranged within the moulding cavity, such that a first gap (72) is provided between the fibre material and the first guide member, and a second gap (74) is provided between the fibre material and second guide member. First and second inserts (78, 80) are inserted into the gap prior to resin infusion.
