Rules of mixtures are mathematical expressions used to estimate properties of composite materials based on the properties and quantities of the constituents. The density of a composite is calculated as the weighted average of the densities of the constituents based on their respective volumes.

The density of a composite is calculated as the weighted average of the densities of the constituents based on their respective volumes. The maximum possible fiber volume fraction is approximately 0.9 for a unidirectional composite, but in practice is typically between 0.6-0.7 due to imperfect alignment. A composite's laminate thickness depends inversely on its fiber volume fraction for a given fiber areal weight - higher fiber content results in a thinner laminate.
