Abstract
A pultruded strip (50) of reinforcing material for stacking with one or more similar strips (50) to form a spar cap for a wind turbine blade is disclosed. The pultruded strip comprises a core (56) comprising fibres (58) disposed in a resin matrix (60) and a sacrificial layer (52) at least partially covering one or more surfaces of the core (56). The sacrificial layer (52) is a resin layer defining an adherend surface (62A) of the strip. A pultrusion process for making such a strip (50) comprises drawing resin-coated reinforcing fibres (58) through a pultrusion die (80) in a process direction to form a core (56) of the strip (50) and applying further resin (53) to one or more surfaces of the core (56) to form a sacrificial resin layer (52) defining an adherend surface (62A) of the strip (50).
