Composite rule of mixtures

WebIn materials science, a general rule of mixtures is a weighted mean used to predict various properties of a composite material made up of continuous and unidirectional fibers. It provides a theoretical upper- and lower-bound on properties such as the elastic modulus, mass density, ultimate tensile strength, thermal conductivity, and electrical conductivity. … In materials science, a general rule of mixtures is a weighted mean used to predict various properties of a composite material .
