For simple, round minerals like calcium carbonate or glass beads, the CTE of the filled plastic is the weighted average of the volume percentage of the plastic and mineral in the mixture i.e. the so-called linear rule of mixtures applies.

WebMay 7, 2024 · What is Rule of Mixtures? The Rule of Mixtures is actually composed of two models: Voigt, W. (1889) and Reuss, A. (1929). The first model is normally applied to calculate elastic modulus on the fiber direction, while the second one is used for estimations on the transverse direction. WebSep 5, 2024 · For all composites, the measured CTE is low or even negative (− 10 ppm K −1) along the z-axis and around 15 ppm K −1 in the x, y -plane. This is geometrically opposite to the properties of the graphite filler (Table 1 ). Aluminum alloys matrices have led to a negative z -CTE. shark vacuum with hepa filter
