Wave transmission through composite laminates is sensitive to lamina orientation and incident angle. Floquet wave analysis explains transmission phenomena, revealing how structure randomness affects wave propagation.

Area of Science:

  • Materials Science
  • Acoustics
  • Composite Materials

Background:

  • Wave transmission through composite laminates is crucial for various engineering applications.
  • Understanding the influence of material properties and structural parameters on wave propagation is essential.

Purpose of the Study:

  • To investigate wave transmission phenomena in multidirectional composite laminates immersed in a fluid.
  • To develop and validate time-domain models for simulating wave transmission.
  • To analyze the impact of lamina orientation, incident angle, and structural randomness on transmission characteristics.

Main Methods:

  • Development of time-domain beam models using a recursive stiffness matrix method.
  • Experimental and theoretical analysis of wave transmission at 2.25 MHz.

  • Interpretation of transmission phenomena using Floquet wave theory.
  • Assessment of the effect of random deviations in laminate periodicity.

    • Main Results:

    • Transmission amplitude strongly depends on lamina orientation and incident angle, with high transmission at small and large angles, and near-zero transmission at intermediate angles.
    • Residue epoxy layers and Floquet waves significantly influence high-frequency transmission and resonances.
    • Random variations in laminate periodicity primarily cause scattering in pass bands at normal incidence.
    • For oblique incidence, random lay-up converges towards a quasi-isotropic composite's transmittivity spectrum.

    Conclusions:

    • Floquet wave analysis effectively explains wave transmission behavior in composite laminates.
    • Lamina orientation and incident angle are critical factors controlling wave transmission.
    • Structural randomness has a limited but notable effect on transmittivity, particularly concerning scattering and convergence of lay-up effects.
