Binalarda kullanılan yapısal olmayan kompozit panellerin fiziksel ve mekanik özelliklerinin değerlendirilmesi

Abstract

 Non-structural composite panels were experimentally studied.  Cellulose fiber reinforced cementitious composites showed, highest strength, lowest deformation and fracture energy.  Cementitious composite with 2.5% glass fiber has the optimum performance Figure A. Physical and mechanical properties of tested compositesPurpose: The purpose of this experimental study is to evaluate the physical and mechanical properties of composite panels used in buildings. Finding the panels having optimum properties in terms of mechanical and physical performance. Theory and Methods: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. Results: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. Conclusion:It has been concluded that glass fiber reinforced cement panels containing chopped glass fiber with 2.5% of glass fiber are the optimum solution in terms of flexural strength-fracture energy and expansion values. The formation of multiple cracks occurred in the composite produced in the industrial line with cement and glass textile. It is obtained that, it is a great advantage to have cement based and oriented fibers in textile form in the desired direction in order to obtain the preferred multiple crack formation and high toughness.
