Abstract: A method of manufacturing a portion of a wind turbine blade is described. The method comprising the steps of: laying up a primary fibre material in a mould; infusing said primary fibre material with a primary resin; substantially curing said primary resin in said primary fibre material to form a cured blade element; laying up a secondary fibre material on top of at least a portion of said cured blade element; infusing said secondary fibre material with a secondary resin different to said primary resin, wherein said secondary resin has a higher strength level than said primary resin; and curing said secondary resin in said secondary fibre material to form an integrated reinforced section on said cured blade element.
