A new composite material has been invented and developed, which possesses both high thermal conductivity and high electrical conductivity. The new composite material is capable of absorbing and dissipating significant amounts of energy within very short time intervals. The material is capable of absorbing and transmitting significant amounts of energy over a distance while maintaining maximum mechanical strength. It demonstrates exceptional reliability in preserving precise geometric shapes under the influence of high concentrations of temperature, energy, and other harmful or extreme impacts. Formulation of the new composite material as a product: ● a composite material featuring an advanced three-dimensional (volumetric) structure composed of numerous identical multi-layered spherical shells encasing spherical cores; the cores with shells (capsules) are bonded together through a series of sequential technological processes and possess an equivalent contact structure form between all capsules. ● the composite material possesses properties of ultra-high thermal conductivity and ultra-high electrical conductivity; ● the composite material exhibits high mechanical strength, is resistant to the development of internal mechanical and thermal stresses, and consequently, to the occurrence of internal deformations; ● the composite material is capable of withstanding high pressures and, under the influence of these pressures, can cause at least some of its components to enter a state of cold-flow behavior. This allows for the calibration of the three-dimensional geometric shape of the structure and ensures very precise geometric dimensions of the structure with a high degree of repeatability.
