5. Discussion The multi-step / random orientation tensor method approximation proved the more accurate, being closer to experimental data. This methodology may be used for creating properties tables for any composites of any number of materials and any number of inclusion geometric shapes. This allows prediction of properties of a composite material before construction. The loops in the methodology allow for calculation of the composite properties even with unknown inclusion properties, meaning that as long as experimental data are available, the methodology can still be applied and during the steps permits the estimation of the inclusions’ properties. Restraining desired properties and using the same method in reverse allows for comparison of different materials with different volume fractions of inclusions. Where density is a factor, it may be used for exclusion of those combinations that do not meet the constraints. Thus, a Cost-Effectiveness analysis comparing the various composite combinations is easily Salvetat J.-P., Bonard J.-M., Thomson N.H., Kulik A.J., Forró L., Benoit W. & Zuppiroli, L. 1999.
