Abstract

A wind turbine blade (1) is formed of a fibre-reinforced composite material comprising a polymer matrix. The blade (1) further comprises a first region (11), a second region (12) and a transition region (13) between the first and the second region (11, 12). The first region (11) is reinforced predominantly with a first reinforcement fibre material (21). The second region (12) is reinforced predominantly with a second reinforcement fibre material (22). The first and the second reinforcement fibre material differ from each other and has differing E-modulus. The transition region (13) additionally comprises a third type of reinforcement fibre material (23) differing from both the first and the second reinforcement fibre material (21; 22) and having an E-modulus between that of the first reinforcement fibre material (21) and that of the second reinforcement fibre material (22).
