The method for making a continuous laminate, in particular suitable as a spar cap or another part of a wind energy turbine rotor blade comprises the steps of providing a plurality of parallel fibers, embedding the fibers in a curable matrix material, curing the matrix material so as to obtain a fiber reinforced laminate having upper and lower major surfaces, and forming channels into at least one of the upper and lower major surfaces of the laminate wherein the channels on the upper and / or lower major surfaces are angled with respect to the direction of the fibers.

A group of multiple hollow fibers may be shaped to introduce angular divergence among the fibers, or to introduce a selected longitudinal oscillation into the fibers. In one shaping technique, the fibers are held in parallel while upper and lower crimping assemblies of parallel crimping bars are drawn together on opposite sides of the parallel fibers. When bars of the opposing assemblies draw sufficiently close, they sandwich the fibers in between them, causing each fiber to assume a shape that oscillates as the fiber repeatedly goes over and then under successive bars. Since the crimping bars are aligned at oblique angles to the fibers, the peaks and troughs of successive fibers are offset. While in this position, the fibers are heated and then cooled to permanently retain their shapes. A different shaping technique utilizes a lattice of criss-crossing tines defining multiple apertures. In this technique, the lattice and fibers are positioned so that each fiber passes through one of the apertures. Then, the lattice and / or the fibers are slid apart or together until the lattice holds the fibers in a desired configuration, where the fibers have a prescribed outward divergence relative to each other. While in this position, the fibers are heated and then cooled to permanently retain this angular divergence. The heating can be effected using heating fluid or gas circulated in the bars.
