Abstract
Geotextiles are commonly produced by needlepunching technology and generally used for various civil engineering applications. Some of these applications require geotextiles to perform more than one function including separation, drainage, and filtration. In this study, the effect of process parameters, namely, feed rate, stroke frequency, and depth of needle penetration has been investigated on various properties of needlepunched geotextiles. These process parameters are then empirically related with the properties of geotextiles. Subsequently, an expert system has been developed to predict the properties of geotextiles for any desired application.
