DEFORMATION OF COMPOSITE-MATERIALS BASED ON MODIFIED THERMALLY EXPANDED GRAPHITE

Samples of thermally expanded graphite modified with aluminosilicates of varying concentration and undergoing bulk tests in conditions of un iaxial compression were investigated. Micromechanical tests were perfo rmed on the surface of the samples by the method of continuous indenta tion with an indenter. The deformation of the surface layer and bulk o f the samples war investigated. It was found that the compressive stre ngth of the samples of modified thermally expanded graphite increased with an increase in the degree elf deformation. Modification of the th ermally expanded graphite powder with aluminum compounds allows fabric ating articles with deformation strength.
