Semi-prepreg for wind power generator vane and production process thereof

The invention relates to a polymer material field, in particular to a semi prepreg for blades of a wind mill generator and a process for manufacturing the same. Unidirectional reinforcing fibers are arranged between an upper layer of flake-shaped reinforcing fibers and a lower layer of flake-shaped...

Zusammenfassung:	The invention relates to a polymer material field, in particular to a semi prepreg for blades of a wind mill generator and a process for manufacturing the same. Unidirectional reinforcing fibers are arranged between an upper layer of flake-shaped reinforcing fibers and a lower layer of flake-shaped reinforcing fibers, and matrix resins are arranged between an upper layer of flake-shaped transverse unidirectional cloth and a lower layer of flake-shaped transverse unidirectional cloth, and partial resins are immersed in inner side surfaces of the upper layer of flake-shaped transverse unidirectional cloth and the lower layer of flake-shaped transverse unidirectional cloth, and the penetration rate of the matrix resins is more than and equal to 10 percent and less than and equal to 80 percent; transverse fibers of the upper layer of flake-shaped transverse unidirectional cloth and the lower layer of flake-shaped transverse unidirectional cloth form a certain symmetrical angle.
