Abstract: A laminate stack composed of layers of composite material and viscoelastic material is disclosed. The composite material is made of fiber bundles bound with a polymer matrix and arranged in a continuous curve. In some of the composite layers, the fiber bundles are made of different kinds of material, called a multi-fiber spatially varying stiffness (MFSVS) composite layer.

The stack can be incorporated into a variety of objects requiring damping, including tubes, sheets, and shells.
