Abstract: A method of manufacturing a portion of a wind turbine blade is described. The method comprising the steps of: laying up a primary fiber material in a mold; infusing said primary fiber material with a primary resin; substantially curing said primary resin in said primary fiber material to form a cured blade element; laying up a secondary fiber material on top of at least a portion of said cured blade element; infusing said secondary fiber 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 fiber material to form an integrated reinforced section on said cured blade element.
