Abstract

The article presents the results of studies of basic physical, mechanical, tribological and electrotechnical properties of composite thermosetting polymeric materials having optimal composition based on solid resin phenol formaldehyde resins and dispersed fibrous filler obtained by mechanical recycling of cellulose fibrous waste products of pulp and paper industry. Physical and mechanical properties (density, tensile and bending strengths, impact strength, degree of absorption for moisture and mineral oil), tribological indicators (wear intensity and stability, friction coefficients in the contact zone of a friction pair under various staticdynamic and thermal loads), electrical characteristics (volume resistivity, electrical strength) and a brief analysis of structural changes in the studied phenolic composites, as well as recommendations for their use as technical products for machine-building and general electrical purposes are presented.
