THE MECHANICAL BEHAVIOR OF UNIDIRECTIONAL COMPOSITELAMINA WITH UNIFORM WAVINESS

Abstract

Abstract: In this paper, the fiber waviness frequently appeared during the manufacturing process of composite wind turbines is investigated. A micro-mechanical finite element model is established to predict the elastic properties of unidirectional lamina with uniform waviness. Parametric modeling method is employed to build up this type of sinusoidal RVE (representative volume element) via ANSYS. Homogenization method and periodic boundary conditions are taken into account in this analysis. The effective stiffness of composites is calculated by stress/strain relation under different loading conditions. Furthermore, the local stress distribution along the fiber direction is acquired by numerical simulation under the axial compression load. Results show that the degree of waviness has great influence on the stiffness of composites. Especially, the longitudinal modulus decreased seriously, and the normal and interlaminar stress change obviously along the waviness direction.

Key words: composites, fiber waviness, finite element analysis, stiffness, stress
