    摘要： Providing composite structures with micro contoured surface layer. There is provided a method to adjust roughness level of micro contoured surface layer when manufacturing a composite and products thereof. The micro contoured surface layer may cover all or at least part of the surface area of the composite product. The roughness level of micro contoured surface layer may be increased or decreased by controlling the process parameters. In particular, there is provided a method to increase the roughness level of composite material having a primary surface layer with a primary surface roughness by softening the primary surface layer of the composite material by heating and providing a secondary surface layer of the composite material surface with a secondary surface roughness by cooling the softened surface layer. Further, there are provided methods to determine and visualize the level of micro contoured surface layer roughness on a composite product surface.

    摘要： The invention relates to a composite comprising matrix material and organic natural fiber material. The composite may be a compound, a granulate, or at least a part of a sound reproduction device. The composite may be made by injection molding. According to an embodiment a composite comprises matrix material and organic natural fiber based material, wherein the matrix material comprises a thermoplastic polymer matrix. The composite may comprise a relative sound wave resistance of 1500-5000. The composite may comprise a relative damping of sound radiation of 1.5-5.0. The composite may comprise a dynamic modulus of 2000-11000 measured according to ISO 6721-3. The composite may comprise a relative acoustic quality factor of 5-200. The composite may comprise a relative factor of viscous damping of 0.500-0.005.
