COMPOSITE ELEMENT WITH POLYMER CONNECTING LAYER

摘要

A composite element (80) includes a base layer (81), a thermoplastic polymer material (83), a thread(82), and a cover layer(84). The base layer has a first surface and an opposite second surface. The polymer material (83) is separate from the base layer(81), extends into the base layer(81), and is at least partially located at the first surface. The thread (82) 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 (82) is bonded to the base layer with the polymer material (83). The cover layer (84) is located adjacent to the first surface and bonded to the base layer (81) with the polymer material (83), and the section of the thread(82) is located between the cover layer (84) and the base layer (81).
