A semifinished product for making a composite fiber molded part is made by first spinning from a row of orifices of a spinning nozzle low-melting fibers of a thermoplastic. These low-melting fibers are then combined into a laminated semifinished product with high-melting reinforcement fibers of the same thermoplastic but having a melting temperature higher than the melting temperature of the low-melting fibers.

A pultrusion process for making a strip for an elongate reinforcing structure of a wind turbine blade, the process comprising drawing fibres (42) and resin through a pultrusion die (40) in a process direction to form a strip (102); and applying an infusion-promoting layer (110) to a surface of the strip down-stream from the die in the process direction. A pultrusion apparatus is also disclosed.

A method of forming a structural element for a wind turbine blade includes fixing a plurality of parallel strength rods to a carrier layer to form a preform layer of material, storing the preform layer in a coiled length, then dispensing the preform layer from the coiled length, partially grinding and then cutting across a width of the preform to form a plurality of cut perform layers, and then stacking them and then fixing them together using a liquid bonding resin material.

The invention relates to a multilayer laid scrim (10, 15) for sheet-like or 3-dimensional high-strength components, consisting of a structure made of a multiplicity of plies of multilayer laid scrim for sheet-like or 3-dimensional high-strength components, consisting of a structure made of a multiplicity of plies made of glass fibres, synthetic fibres, aramid fibres and/or carbon fibres. In order to prevent fan-out of the individual fibres or filaments of the multilayer laid scrim used, it is provided according to the invention that in certain regions structural reinforcement elements (11, 16) are embedded at least into one ply, and/or between at least two plies, of the multilayer laid scrim. Said embedding here can take place over an entire area or else only in the regions which are exposed to a subsequent deformation. The structural reinforcement elements (11, 16) help to generate greater coherence between the individual fibres of the laid scrims, thus preventing fan-out, for example in the edge region.

The present invention relates to novel glass-carbon composites presenting very high directional properties in the UD carbon layer direction greater with improved failure mode as compared to full carbon fiber and standard composite fibers. The invention further relates to a process of preparation of such glass-carbon composites and to articles made from such glass-carbon composites.

A method for producing a component from a fiber-composite material, wherein a plurality of fiber-tape pieces, which each comprise a thermoplastic fiber-tape piece matrix with fiber-tape-piece fibers embedded therein, are provided, the fiber-tape pieces are picked up in the solid state and arranged so as to form a fiber-tape pattern, a backing layer, which comprises a thermoplastic backing-layer matrix with backing-layer fibers embedded therein, is provided and heated such that the backing-layer matrix softens or melts, a preform is formed from the backing layer and the fiber-tape pattern in that the fiber-tape pattern is applied in the solid state to the heated backing layer and is heated thereby so that the fiber-tape-piece matrices soften or melt such that the preform is in a deformable state in which both the backing-layer matrix and the fiber-tape-piece matrices have been softened or melted, the preform in the deformable state is deformed.

A method of forming a sporting implement includes placing a plurality of fibers in a cavity formed in a first portion of a mold, the mold having an inlet and an outlet. A second portion of the mold is positioned in contact with the first portion such that the cavity cooperates with the second portion of the mold to define a chamber. A first material is mixed with a second material to form a thermoplastic resin. The thermoplastic resin is injected into the chamber through the inlet. The inlet and outlet are closed, and the thermoplastic resin completely polymerizes so as to form a fiber reinforced sporting element in the chamber, and the sporting element is removed from the chamber.

A dry, fibrous tape for use in an automated placement process such as ATL or AFP and a preform produced therefrom. The preform is configured for resin infusion. The tape contains a layer of unidirectional fibers, at least one nonwoven veil bonded to one side of the fiber layer, and at least binding materials present within the tape. The preform produced from laying down such tape exhibits a low-bulk property that is close to the final thickness of the cured fiber-reinforced resin article and no further consolidation or compaction is required.

A structural component has a main body formed of a fibre composite material, a plurality of first reinforcement parts and a plurality of second reinforcement parts, wherein the main body is formed as a domed body having a peripheral edge and a vertex, wherein the first reinforcement parts are connected to the main body and in each case have a concave curvature course in relation to a first plane, and wherein the second reinforcement parts are connected to the main body and also have a concave curvature course in each case in relation to a second plane.

A reinforcing article includes a porous substrate layer separating a plurality of parallel first continuous fiber elements spaced apart from each other and extending along a first direction from a plurality of parallel second continuous fiber elements spaced apart from each other and extending along a different direction. Each first and second continuous fiber elements include a plurality of parallel and co-extending continuous fibers embedded in a thermoplastic resin.
