Forecasting the Properties of Multicomponent Mineral Polymer Composite Materials

Introduction. Advances in the construction industry are causing new composite materials to emerge. This is preceded by experimental studies, particularly analytical techniques for predicting the properties of new materials. Polymer composite materials (PCMs) which have proved to be efficient in other industries are commonly utilized in construction as well. PCMs have a number of features that should be taken into consideration while developing analytical techniques. PCM is considered under the condition of isotropy of the final material and compliance with the mixture rule during its manufacture. The objective of the study is to analytically determine the predicted strength limits of multicomponent composite materials with mineral fillers.

Materials and Methods. There are diverse methods for identifying the characteristics of polymer composites. An integral method for determining the modulus of elasticity and the Poisson's ratio of a binary polymer composite material is set forth, based on the assumption that there is a relationship between the elastic potentials of the composite components. The transition of analytical forecasting of characteristics from binary to multicomponent polymer composite material is also shown.

Results. The major characteristic of building polymer composites is their strength. A formula has been obtained for the analytical determination of the predicted tensile strength of a binary polymer composite material, and the predicted tensile strength for some multicomponent polymer composite materials has been obtained based on these formulas as well.

Discussion and Conclusion. The results enable us to conclude that while forming the composition of a multicomponent polymer composite material, it is recommended that fillers with similar characteristics, in particular, elasticity modules are combined.
