A three-dimensional micromechanical model to predict the viscoelastic behavior of woven composites

摘要: Abstract Polymer matrix based cloth composites are increasingly used in engineering applications. For such composites, significant viscoelastic behavior can be observed for dynamic load conditions. The effect is primarily due to the polymeric as most of fibers structural applications elastic. Matrix does not show a major contribution axial properties thus traditional modeling its nature often ignored. However, effective out plane influenced by material and exhibit damping characteristics. Therefore, complete three-dimensional (3-D) model considering needed better understanding composites. An analytical 3-D micromechanical on classical laminate theory (CLT) verified, this paper prediction elastic composite. method shown accurate. This extended regime with use Laplace transform correspondence principle. Prony series coefficients composite obtained different volume fractions yarn. It from hysteresis plots that dissipation normal shear modes significantly higher than directions.
