Comparison between new developed test method (using DMA) and the existing one for measurement of the bending force of monofilaments

The measurement of the bending force of monofilaments used in synthetic sport fields, which determines the quality and the performance in long terms, is still a main discussion on the world of artificial turf. This leads to the need of having précised results of the bending force measured and having the possibility of doing it on different conditions. A new test method has been developed by modifying the DMA equipment in order to use it for measuring the bending force. The results from the measurements are compared with the results from the existing method, Favimat. The aim of this paper is to find a correlation between this two test methods. The monofilaments used are Low Linear Density Polyethylene (LLDPE) and two different distances of applied force are used on the DMA measurement. The comparison of the results showed a good correlation between the two methods on the bending force measured on the 3 mm distance on the DMA and the second cycle on the Favimat.
