Abstract: Methods, computer program products, and apparatuses for reducing sticking during a lithography process are disclosed. An exemplary method of reducing sticking of an object to a modified surface that is used to support the object in a lithography process can include controlling a light source to deliver light to a native surface thereby causing ablation of at least a portion of the native surface to increase the roughness of the native surface thereby forming the modified surface. The increased roughness reduces the ability of the object to stick to the modified surface.

As such, each of the plurality of pultruded rods is received within the enclosed primary outer casing and secured therein via a first resin material. Further, an arrangement of the plurality of pultruded rods within the primary outer casing and a relationship of a maximum dimension of each of the plurality of pultruded rods and a maximum dimension of the enclosed primary outer casing are configured to maximize flexibility of the rotor blade component.

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.
