Abstract
A method for manufacturing a root section of a wind turbine blade includes assembling a mold having an inner cylinder segment, an outer cylinder segment, and a bottom flange, wherein a radial space is defined between the inner and outer cylinders. Root hub connectors are attached circumferentially around the bottom flange so that the root hub connectors extend axially into the radial space. A first cartridge of pultruded rods is loaded into the space, wherein the first cartridge includes a plurality of first pultruded rods arranged adjacent to the inner cylinder segment. The space is sealed, for example with a lid or top flange, and the space is evacuated. A resin is infused into the space so that the resin migrates through the radial space between the pultruded rods, and is then cured. The root section is then removed from the mold. A wind turbine blade root section formed by the method is encompassed by the invention.
