Popis: | The laminated carbon-carbon (C/C) composite is candidate material for plasma-facing components in fusion reactors. Its thermal shock strength must be evaluated for an application to the components facing the high-temperature plasma field. However, few studies have been done. A laser irradiation method newly proposed was applied effectively to lamination of C/C composite for the evaluation of thermal shock strength by subjecting a heat flux up to 27 J/mm{sup 2} on the specimen surface. By introducing the critical power density at which the material fracture occurs, thermal shock strength was obtained. It was concluded that the critical power density could be a new measure to evaluate thermal shock strength for laminated C/C composite. |
