Wind turbine blade manufacturing method

The invention discloses a wind turbine blade manufacturing method. Rigid cushion blocks are embedded into a blade root pavement layer to inhibit the deformation of a soft fibre-reinforced fabric. The rigid cushion blocks are divided a bolt sleeve lower cushion block and a bolt sleeve upper cushion block because of different forms of the rigid cushion blocks; a lower rigid control cushion block is manufactured by taking a blade root cylindrical section of a blade mould as a mould, so that the obtained cushion block shape has good matching property with the blade mould; an upper rigid control cushion block is manufactured by adopting a special mould; through reasonable design of the mould, the fit property between the cushion block and a bolt sleeve upper pavement layer can be ensured. The cushion block is manufactured by adopting pouring resin and the fibre-reinforced fabric which are used for producing the blade, so that the compatibility between the cushion block and the blade can be effectively ensured; an
