Abstract

Se describe un método de fabricación de una parte de un aspa de una turbina eólica. El método comprende las etapas de: colocación de un material de fibra primaria en un molde; una infusión de dicho material de fibra primaria con una resina primaria; sustancialmente curar dicha resina primaria en dicho material de fibra primaria para formar un elemento de aspa curada; por el que un material de fibra secundaria en la parte superior de al menos una porción de dicho elemento de aspa curada; una infusión de dicho material de fibra secundaria con una resina secundaria diferente de dicha resina primaria, en el que dicha resina secundaria tiene un nivel de intensidad más alto que dicha resina primaria; y curar dicha resina secundaria en dicho material de fibra secundaria para formar una sección reforzada integrada en dicho elemento de aspa curada.
