Present-day materials science requires development of compositions and technologies for production of composites with enhanced physical and technical properties. One of requirements towards such materials is an elevated heat strength. Materials, earlier used in electrothermy (ceramics, porcelain, asbestos and items made of them), have operating temperature of 400-500°С, high cost, low mechanical strength and a number of other drawbacks. Therefore, development of heat-resistant, mechanically strong and inexpensive insulation materials is an immediate problem. Mica’s characteristics to the maximum extent meet the requirements to a filler for the composite materials. Its use would enhance electric and physical properties of composites, contribute to development of waste-free technology, thus favoring the environment. Objectives of the paper: development of technology for production of heat-resistant materials on the base of heat-proof mica and special glass with elevated softening point; study of the interaction between composite components and high-temperature medium; giving recommendations on technology for fabricating heat-resistant composites with enhanced physical and technical properties. Objects of study: specimens of heat-proof mica (phlogopite), wastes of abrasive production, modifiers, glasses with high softening point. Methods of investigation: methods of thermodynamic and quantum-chemical studies were used with involvement of a complex of state-of-art physical and chemical methods. Results of study: development of theoretical grounds for forming the heat-resistant composite materials on the base of experimental studies and scientific generalizations. The technology for production of new heat-resistant materials on the base of rational use of mineral raw material and production wastes is proposed.

“…Industrial development requires the application of novel composite materials that display high strength properties and wear resistance [1,2]. It is well known that metal matrix composites containing dispersed carbides, oxides as well as diamond and graphite particles are used to manufacture the triboengineering components [3][4][5].…”

BADANIE STRUKTURY I WŁAŚCIWOŚCI FIZYKO-MECHANICZNYCH SPIEKANYCH MATERIAŁÓW KOMPOZYTOWYCH MIEDŹ-NANOCZĄSTKI WĘGLAPhysico-mechanical and structural properties of electrocontact sintered copper matrix-carbon nanoparticles composite powder materials are presented. Scanning electron microscopy revealed the influence of preliminary mechanical activation of the powder system on distribution of carbon nanoparticles in the metal matrix. Mechanical activation ensures mechanical bonding of nanoparticles to the surface of metal particles, thus giving a possibility for manufacture of a composite with high physico-mechanical properties.Keywords: powder metallurgy, electrocontact sintering, physico-mechanical properties, carbon nanoparticles, composite powder materials, triboengineering characteristics, mechanical activation Materiały kompozytowe o osnowie miedzi zawierające nanocząstki węgla wytwarzano metodą spiekania elektrostykowego. Spieki poddano badaniom właściwości fizyko-mechanicznych oraz badaniom strukturalnym. Obserwacje przełomów za pomocą mikroskopu skaningowego wykazały korzystny wpływ mechanicznej aktywacji mieszanki proszków na rozmieszczenie nanocząstek węgla w osnowie metalowej. Aktywacja prowadzona w wysokoenergetycznym młynie wibracyjnym doprowadza do mechanicznego połączenia nanocząstek węgla z powierzchnią cząstek miedzi, dzięki czemu możliwe jest wytworzenie spiekanego kompozytu o wysokich właściwościach fizyko-mechanicznych.
