Composite rule of mixtures

WebSep 2, 2024 · The term composite could mean almost anything if taken at face value, since all materials are composed of dissimilar subunits if examined at close enough detail. But … WebThe rule of mixtures can also be applied to the friction values of the composite, demonstrating that at the start of testing, the friction coefficient of the compositor depends on the friction coefficient of each component, as well as on the proportions. Due to selective wear, the loading of the couple gradually becomes unevenly distributed.
