Characteristics of shungite particles of different fractional composition and design of compositions of particulate-filled polymer composite materials with different types of structures

The paper presents the results of studies of technological properties (bulk and true density, particle size of the general fraction, particle size distribution, packing coefficient and maximum packing degree of filler particles, etc.) of shungite particles of different batches produced by LLC Nadvoitsky TDM Plant LLC (Karelia, RF). For the first time for shungite particles of different sizes the values of packing density (kуп) and maximum content of dispersed phase (φm) in DFPCM were determined, which allows to calculate generalized and reduced structure parameters, to carry out classification by structural principle and to design compositions of high-tech polymer composites with given properties. Practically all possible compositions of DFPCM with shungite particles of different sizes and different types of disperse structure are presented.
