Abstract

Se describe un aspa de turbina eólica que tiene una transición entre dos tipos de fibras de refuerzo. Una transición gradual es proporcionada por una sección de doble espesor cónico combinado con las primeras fibras tipo refuerzo intercaladas entre las segundas fibras tipo refuerzo o viceversa. El doble ahusamiento se proporciona durante la acumulación y el material de retuerzo se impregna con una resina de polímero y luego se cura o endurece de modo que los dos tipos de fibras de retuerzo estén incrustadas en una matriz de polímero común.
