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. |
