Abstract

A pultruded fibrous composite strip (1) for wind turbine spar caps (30) is presented. The strip (1) has longitudinally extending unidirectional fibers (99) and an elongate body having first and second edge regions (40,60) separated in the longitudinal direction of the strip (1) by an intermediate region (50). The intermediate region (50) has first and second mutually opposed longitudinally extending and parallelly disposed planar surfaces (52,54). The strip's thickness is measurable perpendicular to the planar surfaces (52,54) and the width is measurable parallel to the planar surfaces (52,54) and perpendicular to the longitudinal direction of the strip. In the strip (1), the first and/or the second edge regions (40,60), starting from the intermediate region (50) and extending longitudinally, simultaneously tapers along the width and the thickness of the strip. A spar cap (30) having the aforementioned strip (1), and a wind turbine blade having such spar cap (30) is also presented.
