    Abstract

    This paper presents the results of an experimental investigation conducted to develop a standard test procedure for tension testing on coir yarns and woven coir geotextiles. Uniaxial tension tests were conducted on nine types of woven coir geotextiles and eleven types of coir yarns. Specimens of different dimensions were tested at various deformation rates. Test results indicated that tensile properties of coir yarns and geotextiles were largely influenced by testing parameters. Statistical analysis of yarn tension data was carried out to establish the gauge length, strain rate, and specimen dimensions of geotextiles. Consistent values of tensile strength and failure strain were obtained when gauge length and strain rate were adopted as 150 mm and 5 %/min, respectively. It was also observed that reliable results were obtained when the width of the geotextile specimen for tension test contained not less than ten yarns.
