In this study, physical and mechanical properties of non-structural composite panels used in buildings were determined experimentally. By evaluating the results obtained from the experimental study, the performances of these panels were revealed in terms of physical and mechanical properties. While evaluating the physical performance, its properties such as water absorption and expansion under moisture are taken into consideration. In terms of mechanical properties, four-point bending strengths, fracture energies, tensile strengths and modulus of elasticity values were obtained. The results of the water absorption and expansion tests were evaluated together and the relationships of these properties were revealed. Panels with optimum performance in terms of flexural strength and fracture energy have been determined. According to the results of the experimental study; While cellulose fiber reinforced cement matrix composite gives the highest strength values, cement-based textile reinforced composite panel exhibits the highest fracture energy. It has been concluded that glass fiber reinforced cement panels containing chopped glass fiber are the optimum solution in terms of flexural strength-fracture energy and expansion values.
