Abstract: A method and device are disclosed for forming reinforcement elements from resistant fibers distributed along three dimensions, in which method, a continuous fiber is introduced in a substrate resting on a support formed of such fibers crossed in at least two directions, by stitching, from the free face of said substrate opposite said support by means of a needle driven with a reciprocal movement, a relative movement being in addition generated between said support and said needle so that said continuous fiber is formed inside said substrate of a succession of consecutive segments forming a zig-zag line.The invention is remarkable in that:said needle is curved and imposes on each segment of said continuous fiber a similar curved form; andthe reciprocal movement of said curved needle occurs while rotating about an axis perpendicular to the plane of said needle and disposed on the concave side thereof.

Abstract: A method for manufacturing a preform for producing a part made of composite material with an unchangeable final shape includes supplying a triaxial non-woven textile comprising a layer of fibers orientated in a first direction, a layer of fibers orientated in a second direction, a layer of fibers orientated in a third direction, and seams extending parallel to each other and forming sheaths for the circumferential fibers, arranging the textile on an element of unchangeable shape by placing the seams parallel to the circumferential direction of the element, and sliding the circumferential fibers into the sheaths so that the textile is in continuous contact with the element.

Abstract: A novel reinforcement system for maximizing tensile strength and modulus of elasticity per ply for composite systems has one or more pockets with a first pocket edge, a second pocket edge, a pocket front surface, and a pocket rear surface. The pocket front surface and the pocket rear surface each have a pocket cross-stitch that perpendicularly traverses the pocket. The pocket traverses the fabric parallel and adjacent to the first fabric edge and the second fabric edge in a warp, or 0 degree, or x-axis direction. The pockets contain one or more fiber tows with a plurality of filaments in a stack.

Abstract: The invention relates to a structural mat for reinforcing a wind turbine blade structure. The structural mat comprises two or more groups of bonded fibers, the fibers being bonded by a matrix substantially preventing relative movement of said fibers and wherein said groups are connected to each other by connection means limiting the relative movement of said groups. The invention further relates to a wind turbine blade and a method for manufacturing a wind turbine blade.
