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° C. to about 125° 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.
