  author={Enzo Costamilan and Alexandre Marks L{\"o}w and Marcos D. F. Awruch and Jos{\'e} Humberto S Almeida and Sandro Campos Amico and Herbert M. Gomesa},
The aim of this work is to evaluate damping ratio () of unidirectional carbon fiber15 reinforced epoxy laminates using an experimental approach, which is then input into a finite 16 element numerical model. The logarithmic decrement and the envelope techniques were calculated 17 using Hilbert transform. Flat unidirectional laminates were manufactured by dry-filament winding 18 and evaluated under dynamic free vibration tests (longitudinally and transverse fiber-oriented 19 specimens). Post… Expand
