Full Article:

The work in hand presents the preliminary results of an experimental investigation on the thermo-mechanical properties of a textile refractory composite reinforced with basalt fibers under tensile loading. The composites were produced as a laminate material using five basalt bi-directional fabric layers as reinforcement. A high alumina cement matrix was used in the matrix composition which was designed using the compressible packing method. A series of uniaxial tensile tests was performed under temperatures ranging from 25 to 1000ºC Thermogravimetry analysis were used to study the deterioration/phase changes as a function of the studied temperatures. Scanning electron microscopy (SEM) was used to study the damage process in the fiber-matrix interfaces after exposure to high temperatures.
