18 Claims

1. A carrier material comprising at least

a first thermoplastic fiber layer and

a second thermoplastic fiber layer,

wherein the carrier material is capable of impregnation by an impregnating material,

wherein the first thermoplastic fiber layer and the second thermoplastic fiber layer are nonwoven thermoplastic fiber layers,

wherein fibers in the at least first and/or second thermoplastic fiber layer of the carrier material are filaments, and

wherein at least a part of the first thermoplastic fiber layer and/or the second thermoplastic fiber layer, at at least one boundary of the carrier material, is removed from the carrier material such that a density of a remaining part of the first thermoplastic fiber layer and/or the second thermoplastic fiber layer is maintained, to provide a first part of a form-fit connection.
