<p>The board has two cover layers made of high-pressure laminate (HPL) laminated plastic. A core layer is made of fiber-reinforced thermoplastic materials i.e. polypropylene, with a content of reinforcement fibers i.e. glass fiber, of 35 to 80 weight percentage and a content of air pores of 20 to 85 volume percentage. The cover layers and the core layer are connected with each other by a water-free adhesive, where the adhesive is mechanically fixed in the pores provided on a surface of the core layer. An independent claim is also included for a method for producing a composite board.</p> |
