Estimating the term…
A multi-layered laminated body may especially be used as an interior trim panel in a motor vehicle. The panel includes a substrate, a foam intermediate layer, and a decorative surface layer. The substrate preferably includes three layers, namely a core layer including a natural fiber filler material embedded in a thermoplastic matrix material, and two cover layers comprising natural fibers, glass fibers or polyester fibers in a thermoplastic matrix material. The thermoplastic matrix material is preferably polypropylene. All of the materials of the multi-layered panel are easily broken down or otherwise processed for reuse or recycling. The panels are preferably produced by hot laminating the individual layers of the substrate together and then laminating and molding the decorative surface layer onto the substrate.
A form-stable structural panel including a laminated composite substrate that comprises:
A non-woven fibrous mat including, in stacked arrangement, a first cover layer, a core layer and a second cover layer, wherein said first cover layer and said second cover layer each respectively comprise, intermixed together, fibers of a polyolefin thermoplastic material having a first melting temperature and fibers of a synthetic material having a second melting temperature greater than said first melting temperature, wherein said core layer comprises, intermixed together, fibers of said polyolefin thermoplastic material and natural plant fibers, wherein a content ratio of said thermoplastic material fibers relative to said synthetic material fibers in said first and second cover layers is greater than a content ratio of said thermoplastic material relative to said natural fibers in said core layer, and wherein said first cover layer, said core layer and said second cover layer are connected together in said stacked arrangement.
