A composite element includes a base layer, a thermoplastic polymer
material, a thread, and a cover layer. The base layer has a first surface
and an opposite second surface. The polymer material is separate from the
base layer, extends into the base layer, and is at least partially
located at the first surface. The thread has a section lying adjacent to
the first surface layer and substantially parallel to the first surface
throughout a distance of at least five centimeters, and the thread is
bonded to the base layer with the polymer material. The cover layer is
located adjacent to the first surface and bonded to the base layer with
the polymer material, and the section of the thread is located between
the cover layer and the base layer.
