A vehicle trim product such as an automotive headliner, and method of making same, in which the main structure of the product is formed as a moulding-to-size of a material formed by the joining of straw or tube-like polymeric elements into a coherent mass, the polymeric tubes being caused to cohere by a suitable process of cohesion, for example heat-welding, and incorporating zones or areas of differing resilience and/or compressibility and/or other physical properties within the structure of a one-piece element. By appropriate placement and choice of these zones, the differing requirements of an automotive interior trim product such as a headliner can be conveniently accommodated. The physical properties notably the degree of stiffness and/or hardness and/or resilience, may be varied by varying the physical properties of the tubular or straw-like elements, for example their cross-sectional diameter or major dimension (if not circular), and/or the wall thickness of those elements, and/or by providing a partial or complete filling of material within the internal spaces or voids of those elements. |
