Abstract

PURPOSE:To prevent cracks to be generated in every direction on the platform of a moving blade by forming the platform of the blade with laminated plates composed of unidirectional prepreg members whose fiber directions are different from one another, and respectively providing other laminated plates on upper and lower faces of the platform. CONSTITUTION:A platform 3 is projectingly formed on an outer periphery between a moving blade main body 1 and a blade root 2, and this platform 3 is made by laminating and compress-molding prepreg members. The main body 1, the blade root 2, and the platform 3 are respectively formed by parallelly truing up and laminating laminated plates 4 composed of plural unidirectional prepreg members whose fiber directions are 0 deg., 45 deg., and -45 deg., in a vertical direction Z of the main body 1. Second laminated plates 5 are continuously laminated from the lower face of the platform 3 along the surface of the blade root 2. Furthermore, third laminated plates 6 are wound on the upper face of the platform 3 to cover the face.
