Abstract

It is provided a mandrel for producing a hollow composite component of a wind turbine rotor blade, the mandrel comprising a core (110) of a first material; an outer layer (120) of a second material arranged radially outward of the core, the second material being more compressible than the first material; and a first intensifier member (130) for intensifying a pressure on a first inner area of a lay-up, the first intensifier member being arranged at least partially radially outward of the core, wherein a first outer surface (135) of the first intensifier (130) member and a second outer surface (125) of the outer layer (120), together, forms a defined shape corresponding to a desired inner shape of at least a portion of the hollow composite component.
