"The fracture behaviour of hybrid glass matrix composite samples before and after thermal ageing and/or thermal shock cycling in air has been analysed and evaluated. The fracture toughness values measured were in the range 2.6-6.4 MPam1/2 for the as received material and they were significantly reduced by thermal ageing and thermal shock treatments. The KIc values dropped to 0.4 MPam1/2 for ageing at 700 \u00B0C 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 MPam1/2 for the maximum number of thermal shock cycles from 500 \u00B0C (24 cycles). The damage in the samples due to thermal shock is based on fibre oxidation and porosity formation, as in case of thermal ageing, and, in addition, due to superposed residual thermal stresses in the matrix produced by repeated thermal shocks."@en . . .
