The Influence of Dew Retting on the Mechanical Properties of Single Flax Fibers Measured Using Micromechanical and Nanomechanical Approaches

Ali Reda, Thomas Dargent, Louis Thomas, Sebastien Grec, Lionel Buchaillot, Steve Arscott

The mechanical properties of single flax fibers are characterized here as a function of dew retting. The fibers are measured using micromechanical and nanomechanical techniques over a large retting period (91 days). Damage-free single flax fibers in various stages of dew retting were manually...

Characterization of the adhesion of coatings by surface acoustic waves generated and detected by laser sources, Caractérisation de l'adhérence des revêtements par ondes acoustiques de surface générées et détectées par sources laser

Mustapha Baher

This thesis focuses on material adhesion, which is often crucial to the reliability of coating technologies. More precisely, the adhesion quality of a polyvinyl chloride film to an aluminum substrate is evaluated by Laser-Ultrasonics. Indeed, this non-contact and non-destructive method allows to..., Cette thèse porte sur l'adhésion des matériaux qui est souvent cruciale pour la fiabilité des technologies associées aux revêtements. Plus précisément, la qualité de l'adhésion d'un film en chlorure de polyvinyle à un substrat d'aluminium est évaluée par Ultrasons-Laser. En...
