Strontium aluminosilicate, SrO Al2O3 2SiO2 (SAS), glass-ceramic is being investigated as a matrix material for fiber-reinforced composites for high temperature structural applications. Fracture strengths of hot-pressed SAS glass-ceramic bars were measured in four-point bend from room temperature to 1300°C. The fracture strength of as-processed bars decreased from 156±10 MPa at room temperature to 83 MPa at 1000°C. Bars heat treated at 1100, 1200, and 1300°C for 1 h and 3 h exhibited no change in strength at 1000°C compared to the as-hot-pressed bars.
