Wavy composite is a new form of constrained layer damping that uses continuous fiber
composite with fibers laid in sinusoidal waveforms and viscoelastic materials to provide both
high damping and stiffness.
A finite element code was developed by Patterned Fiber Composites Inc. that predicts material
stiffness and damping of carbon-fiber composite lay-ups with sinusoidally varying properties.
The objective of this research was to test the performance of the finite element code. Finite
