The invention relates to an artificial lawn, in particular for an artificial grass sports field comprising an artificial mat built up of a carrier to which artificial glass fibers are attached. The object of the invention is to provide a new type of artificial lawn, which in particular obviates the need to use an infill material, without this having an adverse effect on the playing characteristics of the sports field. According to the invention, the carrier is at least in part provided with at least one additional material component, which additional material component imposes a permanent volume increase on said part of the carrier under the influence of an external stimulus after being provided in the artificial mat. The use of an additional material component, which imposes a permanent volume increase on at least a part of the carrier, makes it possible to create an artificial lawn having an additional damping property, which has a positive effect on the playing characteristics of the sports field, such as the absorption of shocks, the restitution of energy and the vertical deformation and which furthermore reduces the number of player injuries.
An artificial lawn for an artificial grass sports field comprising a mat comprising a carrier to which a plurality of spaced-apart groups of upright artificial grass fibres are attached, said carrier comprising at least two layers, wherein a first layer of the carrier is at least in part comprised of at least one additional, expandable material component incorporated therein in the form of a yarn, which additional material component expands vertically upward and imposes a permanent volume increase between the spaced-apart groups of upright artificial grass fibres on said part of the carrier when an external stimulus is exerted thereon, said vertical upward volume increase providing a damping layer to the artificial lawn.
