ROTOR BLADE

In the R&D of composite wind turbine blades for the green emerging energy,as China's earliest blade developer with its soild technical strength,SHFRP has become one of development and manufactre base for various types of blades in China.At the end of 2004,the success in the development of the composite blade for 1MW pitch regulated and variable speed wind turbine showed that SHFRP hashad capabilities of designing,developing,manufacturing and testing MW-class blade and its mould independently.
