摘要： The present invention relates to a method of manufacturing a blade shell member for a wind turbine blade. The method comprising providing a blade mould for the blade shell member and arranging a number of fibre-reinforced layers on a blade moulding surface of the blade mould. A first primer layer is applied on top of the fibre-reinforced layers, at a pre-determined spar cap region. Furthermore, a pre-manufactured spar cap having an upper surface, a lower surface, a first side surface, a second side surface, a first end surface and a second end surface is arranged in the pre-manufactured spar cap on the spar cap region, such that the lower surface of the pre-manufactured spar cap contacts the first primer layer arranged on the spar cap region. A second primer layer is also applied to the upper surface of the pre-manufactured spar cap before the step of infusing the blade moulding cavity with resin and curing it. The present invention further relates to a method of manufacturing a wind turbine blade, comprising the steps of manufacturing a pressure side shell half and a suction side shell half over substantially the entire length of the wind turbine blade and subsequently closing and joining the shell halves for obtaining a closed shell.

摘要： A method for manufacturing a quadrangular shell having five faces and non-developable trihedral connectors between the faces. Plies having continuous fibers are cut to cover the five faces of the shell outside of the trihedral connector zones. Four connector components consolidated in the shape of the trihedral connectors are obtained. Each of the components includes an integration zone between the plies. Plies are positioned and laid up. The four consolidated components are inserted in the trihedral connection zones by inserting the integration zones between two plies to form an assembly obtain a preform. The preform is placed in a tool and the consolidation of the stack of fibrous plies is performed by subjecting the assembly to a predetermined pressure/temperature cycle.

摘要： A tie rod suitable for use with known concrete forming systems is constructed from a non-metal fiber, such as fiberglass, that is wound about a pair of opposed thimble elements. The resultant tie rod is as strong as a metal tie rod without the drawbacks of conventional metal tie rods. Each of the thimble elements has a main body having a channel formed in an outer surface of the main body, and the fiberglass fiber is disposed within the channel when wound thereabout.

摘要： A method of fabricating a gas turbine casing out of composite material of varying thickness, the method including making a strip-shaped fiber texture by three-dimensional weaving; winding the fiber texture as a plurality of superposed layers onto a mandrel of profile corresponding to the profile of the casing that is to be fabricated, so as to obtain a fiber preform of shape corresponding to the shape of the casing that is to be fabricated; and densifying the fiber preform with a matrix; wherein, before beginning to wind the fiber texture onto the mandrel, a reinforcing band of width smaller than the width of the fiber texture is placed on the mandrel in a zone that is to form a retention zone of the casing.

摘要： A duct stringer has duct walls providing a duct with a closed cross-section; and a bulkhead in the duct. The duct is adapted to transport fluid, and the bulkhead is adapted to block the flow of fluid along the duct. The bulkhead is adhered to the duct walls by one or more co-cured or co-bonded joints. The bulkhead includes a pair of bulkhead parts, each with a web and one or more flanges. The duct stringer is manufactured by positioning the mandrels end-to-end with the bulkhead parts back-to-back between them; wrapping or laying-up the duct walls around the bulkhead parts and the mandrels; co-curing or co-bonding the flanges of the bulkhead parts to the duct walls; and after the bulkhead has been adhered to the duct walls, removing the mandrels from opposite ends of the duct.

摘要： The invention relates to an improved filament-reinforced tubular, and a method for providing such a tubular. A filament-reinforced tubular according to the invention comprises a tubular body (2), the tubular body comprising multiple fibre mats (10) encapsulated in a thermoset material (11), and is at least at one end provided with a male screw thread (3) comprising threading. According to the invention, the threading comprises a core member (12, 16). Furthermore, the threading comprises one or more fibre mats (13) that cover the core member. The one or more fibre mats are pulled between the windings of the core member by a positioning wire (14). The core member, the one or more fibre mats, and the positioning wire, are encapsulated by a, preferably thermoset, cover material (15), which cover material defines the shape of the screw thread.
