## how to find density of a composite material

### Rule of mixtures - Wikipedia

In 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 general there are two models, one for axial loading, and one for transverse loading. In general, for some material property E {\displayst

### Estimations of composite materials properties [SubsTech]

Rule of Mixtures is a method of approach to approximate estimation of composite material properties, based on an assumption that a composite property is the volume weighed average of the phases (matrix and dispersed phase) properties. According to Rule of Mixtures properties of composite materials are estimated as follows:
