The acoustic properties of carbon fiber, specifically its sound absorption coefficient (Noise Reduction Coefficient, NRC), are not readily available due to its complex nature as an anisotropic composite material. Variations in bonding agents, lattice geometry, and laminate layers further complicate the establishment of general material property values. There is a lack of comprehensive reference materials in the field of materials engineering that detail the acoustic properties of carbon fiber compared to other materials like fiberglass. Users seeking specific acoustic impedance values for materials such as paper also face similar challenges in finding definitive resources.
PREREQUISITESMaterials engineers, acoustics researchers, product designers, and anyone involved in the study of sound absorption in composite materials.
Topher925 said:Carbon Fiber is typically an anisotropic composite material and also can use many different kinds of bonding agents, lattice geometry, laminate layers, etc. I don't think you will find any general material property values for a composite material such as carbon fiber.
