FIELD: chemistry.
SUBSTANCE: group of inventions relates to composite materials containing silicon carbide fibres and articles made from said materials. Disclosed is a method of processing silicon carbide fibre, which includes the following steps. Contact of silicon carbide fibre, having oxygen content less than or equal to 1 at. %, with oxidative medium at temperature of 600–1000 °C to form surface layer of silicon oxide, obtained silicon oxide layer is removed by treatment with acid and deposition of interfacial layer on surface of acid treated fibre.
EFFECT: invention improves mechanical properties of the composite material.
