- Annotation: The issues of designing structures of textile blanks made of carbon materials and intended for produc-tion of carbon-carbon brake discs for the aviation industry formed on the basis of frame fabrics and needle-punched nonwoven fabrics, are reviewed. Qualitative parameters of the fabrics and needle-punched nonwoven fabrics, affecting the properties of the resulting composite material, are reviewed. It is established that the structure of frame fabrics and the process of formation of needle-punched nonwoven fabrics on their basis, is what the quality of blanks significantly depends on; that also has an indirect impact on the strength and operational properties of carbon-carbon brake discs. It is established that the use of fabric with a surface density of 400 g/m2 to create carbon-carbon composite materials based on needle-punched frames, compared to samples based on fabric with a surface density of 600 g/m2, allows increasing the volume fraction of fibre, reducing porosity in the composite. Using fabric with a surface density of 400 g/m2 the relative proportion of long dimension pores significantly increases, indicating an increase in the total surface area at the phase boundary.
