Abstract
A method for determining the recovery grade in artificial fiber carpets, such as artificial turf, including obtaining samples of the artificial fiber carpets to be examined in order to capture an image, by a camera and lightbulb under conditions of controlled exposure, of the area of the fibers which will subsequently be subjected to supporting a load. In a certain area of the fibers, in a vertical compressive manner, a load of known mass during a predetermined time is applied, for once the load is released, capturing elevational images, according to the same area of the fibers subjected to the load, at predetermined time intervals. The recovery index of the fibers subjected to analysis based on the area occupied by the fibers is determined before being subjected to the load and after the different predetermined time intervals.
