Wind turbine rotor blade components and methods of making same
First Claim
1. A composite beam for a wind turbine blade comprising:
- a preform layer, the preform layer including multiple elongate strength rods arranged longitudinally relative to one another in a single layer, each strength rod being disposed adjacent to and spaced from at least one adjacent strength rod;
each strength rod having a rectangular cross section and including multiple, substantially straight collimated structural fibers fixed in a solidified matrix resin;
the preform layer including at least one carrier layer to which the multiple strength rods are joined by an adhesive;
wherein the carrier layer spaces adjacent strength rods a fixed distance apart to facilitate the flow of liquid bonding resin between adjacent strength rods of the preform layer to its joined carrier layer, the carrier layer being of a permeable material suitable to facilitate the flow of liquid bonding resin through the carrier layer.

Abstract
A composite beam for a wind turbine blade includes a preform layer, the preform layer including multiple elongate strength rods arranged longitudinally relative to one another in a single layer, each strength rod being disposed adjacent to and spaced from at least one adjacent strength rod. Each strength rod has a rectangular cross section and includes multiple, substantially straight collimated structural fibers fixed in a solidified matrix resin. The preform layer includes at least one carrier layer to which the multiple strength rods are joined by an adhesive. The carrier layer spaces adjacent strength rods a fixed distance apart to facilitate the flow of liquid bonding resin between adjacent strength rods of the preform layer to its joined carrier layer, the carrier layer being of a permeable material suitable to facilitate the flow of liquid bonding resin through the carrier layer.
