Evaluation of Bending Resistance of Gypsum Composite with Perforated Non-Woven Fabric using Response Surface Methodology

Gypsum is one of the most useful building materials in building industry due to its unique properties. But it is weak against bending and tensional forces acting on it. Therefore in this kind of building material to overcome the structure weight and also improving mechanical properties, textiles can be used as reinforcing member due to their tensional property and low weight. In this research, perforated non-woven fabric and its waste affection on bending resistance of gypsum composite has been evaluated. Response surface method has been used to analyze bending property of gypsum composite as dependent variable. Non-woven fabric weight, the number of holes and this kind of fabric waste has been selected as independent variables. As a result of this study bending resistance predictive model of gypsum composite is provided and this model has a high coeffcient of determination. Also according to the results of this study, it was determined that using textile materials in the form of fabric waste will follow more considerably effect on improving bending property of gypsum composite than the perforated fabric.
