Abstract

Pá de hélice para um rotor de uma turbina eólica. Uma pá de hélice do rotor (140) para uma turbina eólica (100) inclui uma secção de flange configurada de modo a conectar a dita pá de hélice do rotor ao cubo do rotor (130). A secção de flange é formada a partir de um material híbrido, o qual compreende fibras de vidro (10) e fibras de carbono (15) embebidas em um material de matriz (20). As fibras de carbono são orientadas de forma substancialmente paralela ao eixo longitudinal da dita pá de hélice do rotor.
