摘要： Fabric (20) comprising:
i) a first fiber layer (21, 22, 23, 24) and a second fiber layer (21, 22, 23, 24), wherein the first fiber layer (21, 22, 23, 24) and the second fiber layer (21, 22, 23, 24) are laid on top of each other; and
ii) a yarn (25), wherein the yarn (25) extends through the first fiber layer (21, 22, 23, 24) and the second fiber layer (21, 22, 23, 24) and thereby fixates the first fiber layer (21, 22, 23, 24) to the second fiber layer (21, 22, 23, 24). The yarn (25) is made of or comprises a synthetic material, in particular a thermoplastic material, having at least one epoxy-compatible group and/or a group reactive towards epoxy.

摘要： The invention refers to a wind turbine blade integrating a lightning protection system. The wind turbine blade comprises one spar cap formed by a plurality of carbon plates stacked together. The wind turbine blade comprises a first down-conductor placed alongside the tip region of the spar cap, and a second down-conductor placed alongside the root region of the spar cap. The first down-conductor extends from the spar cap's tip end towards the spar cap's mid region, and terminates at a first down-conductor's end located adjacent a first region of the spar cap which extends from a cross-sectional area of the spar cap which area is equal or higher than 75% of the maximum cross-sectional area of the spar cap, being that area the one closest to the spar cap's tip end, to a cross-sectional area of the spar cap which area is 100% of the cross-sectional area of the spar cap, being that 100% of the cross-sectional area the one closest to the spar cap's root end.
