| Description
| - V práci bylo analyzováno lomové chování hybridního kompozitu se skelnou matricí před a po teplotním stárnutí a tepelných šocích. Pro hodnocení lomové houževnatosti byla použita technika ohybových vzorků s chevronovým vrubem. Hodnoty KIc se pohybovaly v intervalu 2.6-6.4 MPam1/2 v případě materiálu v dodaném stavu a byly výrazně nižší u vzorků po tepelné expozici. V tomto případě se lomová houževnatost KIc snížila na 0,4 MPam1/2 pro stárnutí po dobu 24 h na 700 °C a to v důsledku oxidace vláken, a tvorby dutin v matrici spojené se změkčováním matrice. Hodnoty KIc klesly na 1,3 MPam 1/2 po 24 tepelných šocích z 500 °C resp. na 1,1 MPam 1/2 po 50 tepelných šocích z 600 °C. Poškození vzorků v důsledku tepelných šoků bylo vysvětleno oxidací vláken a tvorbou pórů v případě tepelného stárnutí a dodatkového zbytkového pnutí v matrici produkovaného opakovanými tepelnými šoky (cs)
- The fracture behaviour of hybrid glass matrix composite before and after thermal ageing and/or thermal shock cycling in air has been analysed. Chevron notch technique was applied for fracture toughness determination. The KIc values were in the range 2.6-6.4 MPam 1/2 for the as received material and they were significantly reduced by thermal loading. The KIc values dropped to 0.4 MPam 1/2 for ageing at 700 C for 24 h due to fibre oxidation and porosity formation in the matrix as a result of softening of the glass. The KIc values decreased to 1.3 MPam 1/2 for the 24 thermal shock cycles from 500C and/or to 1.1 MPam 1/2 for 50 cycles from 600C. The damage in the samples due to thermal shock cycling was explained by fibre oxidation and porosity formation, as in case of thermal ageing, and, in addition, by superposed residual thermal stresses in the matrix produced by repeated thermal shocks
