The purpose of this study is to investigate the processes of obtaining and characteristics of the C-SiO2 composite obtained from plant waste and to assess its potential as a reinforcing component in structural carbon materials. The methods used include analytical method, classification, functional method, statistical method, synthesis. In the course of the study, a C-SiO2 composite was obtained from lignin extracted from rice straw after hydrolysis in an autoclave at a temperature of 200°C using a 1% solution of H2SO4. The resulting composite contains 70% of the material and has morphology characterised by fibres and dendrites of carbon particles of various sizes. X-ray diffraction analysis revealed the presence of graphite-like, naphthenic and hydrocarbon phases with their corresponding content, which makes it potentially effective filler for structural carbon materials. The use of this new carbon material containing 30% C-SiO2 composite in the manufacture of products using standard technology has demonstrated improved wear resistance and long service life in abrasive conditions, which makes it promising for various industries.
