Abstract
Filament-reinforced nonwoven-fabric sheeting reinforced by sheets of parallel reinforcement yarns integrated into the nonwoven-fabric sheeting, whereby a binder is used to bind the filaments A forming the nonwoven fabric to filaments B of the reinforcement yarns at the crossing points of filaments A and B, and to bind filaments B to each other at least at some points, wherein the filaments A of the nonwoven fabric are also bound to each other at their crossing points by the same binder is disclosed.
