1. A composite beam for a wind turbine blade comprising:
a plurality of stacked preform layers, each of the plurality of stacked preform layers 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 of the plurality of stacked preform layers also including a carrier layer to which the multiple elongate strength rods are joined to form the preform layer;
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; and
further comprising one or more layers of at least one of a fibrous woven material or a fibrous non-woven material stacked with the plurality of stacked preform layers.
