Abstract:
A pultrusion process for making a strip for an elongate reinforcing structure of a wind turbine blade, the process comprising drawing fibres (42) and resin through a pultrusion die (40) in a process direction to form a strip (102); and applying an infusion-promoting layer (110) to a surface of the strip down-stream from the die in the process direction. A pultrusion apparatus is also disclosed.
