A flat material, eg a mat, a moulding or a fleece, comprises sections made of a plastic layer or coating, applied by flame spraying. The material has a substrate containing natural fibres, eg coconut, jute, hemp, cellulose or cotton fibres. Alternatively the substrate is made of card, ceramic material or plastic, with a high melting point. A plastic material is thermally sprayed onto the substrate at its connection points with another component made of a thermoplastic material, and the latter is then welded. The welding is either vibration, hot air or heater welding. An Independent claim is also included for the process for making the product. |
