Prediction of Dissipative Properties of Flax Fibers Reinforced Laminates by Vibration Analysis

Autor: Ali El Hafidi, Stéphane Fontaine, Marouane Belaïd, Papa-Birame Gning, Papa Benoît Piezel

This study proposes an experimental-numeric method to identify the viscoelastic properties of flax fibres reinforced composite laminate (flax/epoxide). The used method consists in identifying the evolutions of both loss factor and stiffness when vibr
