A methodology of making and effective usage of composite materials based on multicomponent natural and technogenic raw materials has been developed, which implies the implementation of: a proper theoretical concept; some established relations between the master characteristic function, process parameters and performance indices; physicochemical and information criteria of matrix selection; a system of computer graphic studies; a manufacturing technique to afford excellent performance and multifunctionality for the composites. Power dependencies of the performance indices of solid materials on the specific formation enthalpy and extremal dependencies of the specific enthalpy and performance indices on the density and specific heat capacity have been found, the maxima being within 3.2-4.1 g/icm3 and 0.5-0.8 J/g-K, respectively.
