1. A prefabricated half-product for use in manufacture of a fiber-reinforced composite part of a wind turbine, comprising an inlay and a fiber mat, wherein the inlay comprises a metal or reinforced carbon fiber composite material and is attached to a surface of the fiber mat magnetically, or by gluing, sewing, tethering, stapling, clipping, clamping or riveting, such that the relative position of the inlay with respect to the fiber mat remains substantially fixed during the manufacture of the fiber-reinforced composite part of the wind turbine. 2. The half-product according to claim 1, wherein at least two inlays are attached to the surface of the fiber mat, such that the relative position of the at least two inlays to each other on the fiber mat remains substantially fixed during the manufacture of the fiber-reinforced composite pan of the wind turbine. 3. The half-product according to claim 1, wherein a filler material is arranged on the fiber mat. 4. The half-product according to claim 1, wherein the inlay is attached between two fiber mats. 5. The half-product according to claim 4, wherein the inlay is attached between the two fiber mats by at least one of pre-laminating the two fiber mats and partially laminating the two fiber mats in a region close to the inlay. 6. The half-product according to claim 1, wherein the inlay comprises a clip, a clamp or a hook for attaching the inlay to the fiber mat. 7. The half-product according to claim 1, wherein the inlay comprises a fixing eyelet, a recess and a groove-shaped depression for attaching the inlay to the fiber mat. 8. The half-product according to claim 1, wherein the inlay comprises a carrot, a bushing, a threaded rod, a bolt, a hinge, a fixing point or a flange for use during transport, assembly, repair or service of the wind turbine or parts thereof or for attaching the fiber-reinforced composite part to another part of the wind turbine or to parts thereof. 9. The half-product according to claim 1, wherein the inlay comprises an aerodynamic means selected from a group consisting of a blade tip a leading edge and a break flap. 10. A method for forming, a pre-fabricated half-product for use in manufacture of a fiber-reinforced composite part of a wind turbine, comprising: providing a first fiber mat; andattaching an inlay comprising a metal or reinforced carbon fiber composite material to a surface of the first fiber mat by gluing, sewing, tethering, stapling, clipping, clamping or riveting, such that a relative position of the inlay with respect to the first fiber mat remains substantially fixed during the manufacture of the fiber-reinforced composite part of the wind turbine. 11. The method according to claim 10, further comprising: arranging the inlay in a holder comprising a fastener for the inlay. 12. The method according to claim 10, further comprising: arranging a second fiber mat on the inlay. 13. The method according to claim 10, further comprising: pre-impregnating or pre-laminating the first fiber mat. 14. The method according to claim 10, further comprising: arranging a filler material on the first fiber mat. 15. The method according to claim 10, further comprising: cutting into parts or tailoring the first fiber mat with the attached inlay such that half-product or half-products are trimmed to fit together with at least one further mat for forming the fiber-reinforced composite part of a wind turbine in a mold. 16. A method for forming a fiber-reinforced composite part of a wind turbine, comprising: arranging, a pre-fabricated half-product in a mold, the pre-fabricated half-product comprising a fiber mat and a metal or reinforced carbon fiber composite inlay attached to a surface of the fiber mat;arranging at least one further fiber mat in the mold such that the at least one further fiber mat is in contact with the pre-fabricated half-product;impregnating fiber such that the pre-fabricated half-product and the at least one further fiber mat are resin impregnated; andcuring the resin to form the fiber-reinforced composite part of the wind turbine. 17. The method according to claim 16, further comprising: providing a holder comprising a fastener for the inlay. 18. The method according to claim 16, wherein the fiber-reinforced composite part is a blade or a housing of a wind turbine or a part thereof.
