Tensile Test on Non-Woven Geotextiles

Tensile test on non-woven geotextiles with optical long-travel measuring system, using hydraulic specimen grips, to EN ISO 10319. The main feature of this method of determining the tensile strength of fabrics is the width of the specimen: for the basic test, the specimen width  (200mm) is greater than the length (100mm), as some geotextiles have a tendency to contract, or ‘neck down’, at an angle to the force direction under tensile loading. The extra width reduces the ‘neck down’ effect, providing a relationship closer to expected product behavior in this area.
