## Description

- description: Polyacrylonitrile (PAN)-based and pitch-based carbon fibers　exhibit
    significant anisotropies in the radial and axial directions. Characterizing the
    anisotropy of the elastic properties of PAN-based and pitch-based carbon fibers
    is important for carbon fiber research communities. In this present study, the
    Raman scattering for anisotropy of PAN-based and pitch-based carbon fiber-reinforced
    plastic (CFRP) samples was investigated. The Raman scattering parameters and ratios
    in the CFRPs with 0°, 45°, and 90°-sections are related to the tensile modulus.
    These linear trends for the PAN-based and pitch-based CFRPs with 0°, 45°, and
    90°-sections intersect in the range of 400–700 GPa. The change of Raman scattering
    parameters and ratios of PAN-based and pitch-based carbon fibers and CFRPs with
    0°-section are related to the tensile modulus. These linear trends also intersect
    in the range of 400–700 GPa. The intensity ratios increased with increase in the
    angle for each CFRPs. The intensity ratio in an arbitrary angle could be estimated
    using the rule of mixtures and coordinate transfor-mation equations. The Raman
    anisotropic nature of PAN-based and pitch-based fibers are identified through
    experimentally and analytically.
