Abstract: The microstructure of laminates is changed by z-pinning. In order to understand the fiber stress distribution in prepreg composites with insertion of z-pins, finite element analyses are conducted based upon the micromechanics model. The uncured resin matrix is modeled by viscoleastic constitutive equations. The fiber stress relaxation behavior with time is revealed.
Key words: composites laminate, fiber waviness, stress relaxation, viscoelastic
