Embodiments of the present application generally provide for wind turbine blade spar caps comprising composite materials prepared using a low viscosity resin system and a high density fabric and methods for their manufacture. In particular embodiment, the low viscosity resin system has a viscosity in the range of about 1 to about 100 centipoises at a temperature in the range of about 0&#xb0; C. to about 125&#xb0; C. during the preparation of the composite material. By using low viscosity resin systems, composite materials have been prepared having a fiber volume fraction of greater than about 65% and a composite modulus of greater than 48000 MPa.

Method for manufacture of an infused spar cap using a low viscosity matrix material

A method for assembling a rotor blade for use with a wind turbine. The method includes providing a blade sidewall at least partially defining a cavity extending from a blade root towards a blade tip of the rotor blade, the blade sidewall having a leading edge and a trailing edge. A structural support assembly is positioned at least partially within the cavity and extends from the blade root towards the blade tip. The structural support assembly includes a root end and an opposing tip end. At least one support member is coupled to the blade sidewall and to the structural support assembly.

Rotor blade for use with a wind turbine and method for assembling rotor blade

A blade for the use in the generation of power has a leading edge and a trailing edge. A first shell portion of the blade extends from the leading edge to the trailing edge. A second shell portion of the blade also extends from the leading edge to the trailing edge. A root portion of the blade is positioned proximate the wind turbine and a tip portion which extends from the root portion away from the wind turbine. A trailing edge insert is positioned between the first shell portion and the second shell portion proximate the root portion. The trailing edge insert has a surface which extends between and separates the first shell portion from the second shell portion at the trailing edge, such that the insert provides a high lift profile for increased blade efficiency.

Flatback insert for turbine blades

A blade of a wind turbine is provided having an improved spar cap. The spar cap includes at least one trench extending in a substantially span-wise direction in at least a portion of the spar cap. At least one shear web is connected to the spar cap. At least a portion of the shear web is positioned within the trench of the spar cap.
