In general, the composite elastic modulus increases with the decrease of the mean fiber orientation angle and with the increase of the fiber orientation coefficient; and the elastic modulus increases with the increase of mean fiber length when the mean fiber length is small. When the mean fiber length is large, it has nearly no influence on the elastic modulus of short fiber reinforced composites.

The utility of specific modulus is to find materials which will produce structures with minimum weight, when the primary design limitation is deflection or physical deformation, rather than load at breaking—this is also known as a 'stiffness-driven' structure. Many common structures are stiffness-driven over much of their use, such as airplane wings, bridges, masts, and bicycle frames.
