A spar cap assembly for a rotor blade of a wind turbine is disclosed. In general, the spar cap assembly may include a tensile spar cap formed from a composite material and configured to engage an inner surface of the rotor blade. The tensile spar cap may generally have a first thickness and a first cross-sectional area. Additionally, the spar cap assembly may include a compressive spar cap formed from the same composite material and configured to engage an opposing inner surface of the rotor blade. The compressive spar cap may generally have a second thickness and a second cross-sectional area that is greater than the first cross-sectional area. Additionally, the composite material is generally selected so that at least one of a strength and a modulus of elasticity of the composite material differs depending on whether the material is in tension or in compression.
