Kabat O. Scientific and technical bases of manufacturing technology of heat-resistant polymeric composite materials of tribotechnical purpose

This dissertation is based on the solution of an important problem of creation of scientific and technical bases of manufacturing technology of heat-resistant polymeric composite materials (PCM) with low prime cost and available production in the conditions of the companies of Ukraine and with the best level of properties than the existing analogs have for tribotechnical units of modern machines and mechanisms that works at high loads levels, sliding speeds and temperatures. A new resource-saving technology for the production of heat-resistant PCM on the basis of aromatic polyamide phenylon C1, fluoroplastic-4 and diphenylolsulfonformaldehyde oligomer (DFSFO) with evenly distributed in their volume dispersed material was theoretically substantiated and developed. This is achieved by combining (in situ) fine particles of polymers with a filler in the synthesis of silica gel from an aqueous solution of sodium silicate. The developed technology allows to refuse operation of mechanical mixing of initial components of polymeric compositions at a preparatory stage of processing that considerably simplifies and cheapens technology of manufacturing of details from the developed PCM and promotes reception of polymeric compositions with high quality of distribution of initial components Systematic researches on an estimation of influence of PCM structures and technologies of their processing on thermophysical, physical-mechanical and tribological properties of products from them were carried out. The optimization of the compositions of the developed PCM from the point of view of tribological properties was performed. Recommendations for introduction of details from the created PCM in the industry were developed. Their industrial researches were carried out at the enterprises of LLC « Т TORP GROUP», LLC «KODATSKE-AGRO», NPE «SOYUZ-KOMPOSIT», LLC «KHIMPOSTACH DNIPRO», LLC « INTER AVIA INVEST».
