Damage recovery after impact in E-glass reinforced poly(epsilon-caprolactone)/epoxy blends

Véronique Michaud, Amaël Maximilien Cohades

Damage recovery after low-velocity impact has been assessed in woven E-glass fibre-reinforced polymer composites with an epoxy matrix and a blend of epoxy and 25 vol% of poly(e-caprolactone) (PCL). Impact was carried out at three energy levels (8.5, 17, 34 ...

Influence of processing routes on morphology and low strain stiffness of polymer/nanofibrillated cellulose composites

Yves Leterrier, Pierre-Etienne Bourban, John Christopher Plummer, Sylvain Cyril Claude Galland, Lars Berglund

The morphology of polymer/nanofibrillated cellulose (NFC) composite sheets produced using different techniques and its influence on low strain stiffness were assessed by optical and transmission electron microscopy. Solvent processing led to relatively hom ...

Time-intensity transformation and internal stress in UV-curable hyperbranched acrylates

Yves Leterrier, Lars Schmidt

The photocuring of three different highly functional acrylates—Di-pentaerythritol penta/hexaacrylate (DPHA) and two hyperbranched molecules (HBP), one with a stiff polyester and one with a more flexible polyether structure—was investigated by means of phot ...
