The results show that the blade steel's strength will decrease as the temperature rises;its elongation and reduction of area will go down slowly at low temperature;its plasticity will be lowest at the medium temperature,and then will increase .

The foundation for drawing-up Ben Gang standard of blade steel,steel trade mark,specification test method and delivery condition are introduced in this paper.

Blade steel is one of the main product of our company,but the ferrite contents of large quantity of blade steels produced in 2005 didn\'t meet the requirements of the related standards,which caused consumer\'s quality objection and wicked influence to our company.

In this paper,a generalized finite-element-based cross-sectional analysis for nonhomogenous,initially curved and twisted,anisotropic GRP blades is formulated from geometrically nonlinear,three-dimensional(3-D)elasticity.

This paper presents the load spectrum and an engineering estimating method of the fatigue life of GRP blade of large-scale wind turbine.

The engineering estimation method of the fatigue life of largescale wind turbine GRP blade were presented.
