Abstract: In the present work the thermo-mechanical properties of a textile refractory composite rein-forced with basalt fibers under tensile loading was investigated. A series of uniaxial tensile tests was performed under temperatures ranging from 25 to 1000°C. The composites were produced as a laminate material using five basalt bi-directional fabric layers as reinforce-ment. A high alumina cement matrix was used in the matrix composition which was de-signed using the compressible packing method. Thermogravimetry analysis were used to study the deterioration/phase changes as a function of the studied temperatures. Scanning electron microscopy (SEM) was used to investigate the hydrated products formed in the matrix and the damage processes in the fiber–matrix interfaces after exposure to high tem-peratures.
