Estimating the term…
A pultruded fibrous composite strip, a spar cap made from such strips, a wind turbine rotor blade having such a spar cap and a method for making a spar cap from such strips is provided. The strip is stacked with similar strips to form the spar cap. The strip has a substantially constant cross-section defined by first and second mutually opposed and longitudinally extending sides, and by first and second longitudinal edges. The first and the second sides include first and second abutment surfaces, respectively. The first and the second abutment surfaces are non-planar. When the strip is stacked with similar strips, and subsequently integrated within shell of the wind turbine blade, the non-planar profile of the strips at least partially obviates formation of resin rich pockets at the interface of the spar cap and the shell and/or stress concentration between the edges of the spar cap and the shell.
