The purpose of the work is the development of carbon-carbon composite materials (CCCM) and the manufacturing technology of carbon and combined fibrous reinforcing frames for carbon saturation, optimization of the composition and structure of preforms and composites according to the wear resistance criteria of aircraft brakes. Research methods - optical microscopy, porosity measurements, determination of thermophysical properties, friction tests according to the criteria of aircraft brakes. A new reinforcing material for carbon pre-saturation in the form of knitted weft webs containing high-strength carbon fibers from PAN precursors and Ural hydrated cellulose fibers has been proposed. It is shown that the porous structure of carbon fiber preforms is characterized by the presence of open porosity of the transport type and provides the necessary porosity for the saturation of interfiber and interfilament type space with carbon. It was determined that the structure of the CCCM inherits the main features of the initial structure of knitted fabrics, has a characteristic installation of СС and texture depending on the types of СС used. It is shown that the use of preforms from knitted weft webs contributes to a uniform distribution of the carbon matrix in the CCCM volume. The use of СС with PAN precursors makes it possible to obtain materials with a specific gravity of 1.71-1.73 g/cm3. The knitted technology of weft weaves makes it possible to improve the quality of the saturation, to provide the desired anisotropy of properties by the spatial arrangement of СС. The thermal conductivity of CCCM using СС with PAN precursors has higher experimental and calculated characteristics. The tribotechnical properties of the developed CCCM meet the criteria of materials for aircraft brakes Product Description popup.authors Andriyenko Olena M Ataman Iryna I Bezsmertna Viktoriya I Varchenko Viktor T Vasylenkov Yuriy M Volynko Volodymyr I Gorbik Valentin P Danylyuk Valentyna M Dyadechko Oleksandr H Kazimirova Galina I Korolyov Mykola O Kostenko Oleksiy D.
