The modulus of elasticity (A measure of the stiffness of a material, defined as the axial stress divided by the axial strain. The higher the modulus, the stiffer the material.) for carbon fiber is typically 33 msi (228 GPa) and its ultimate tensile strength is typically 500 ksi (3.5 Gpa).
Stiffness of Carbon Fiber: 33 msi (228 GPa)
