IDENTIFICATION OF RESIDUAL STRESSESIN PRODUCTS FROM CARBON- CARBONACEOUSMATERIALS
Abstract and keywords
Abstract (English):
The method of assessing the level of residual stresses in graphitic carbon shell of revo-lution, by interpreting the experimental data obtained by the x-ray method is proposed. The results of experimental studies of mental-phase composition, the parameters of the crystal lattice, the degree of graphitization and texturing of pyrolytic reinforced carbon-carbonaceous composite are given. Estimation of the level of residual technological tensions resulting in defects of products has been performed at the micro and macro stages. Quality criterion is written as a deviation square sum, calculated and measured broa-dening of diffractogram lines. High informativity of the radiographic method for estimating artificial graphite prod-uct quality and the possibility of using this method in the production environment.

Keywords:
identification, composite materials, radiographic method, residual stresses non-destructive testing.
