On the durability of surgical masks after simulated handling and wear

Jian Wang, Véronique Michaud, Baris Çaglar, Vincent Marc Varanges, Yann Albert Gérard Lebaupin

After the spread of COVID-19, surgical masks became highly recommended to the public. They tend to be handled and used multiple times, which may impact their performance. To evaluate this risk, surgical masks of Type IIR were submitted to four simulated tr ...

Deconsolidation in glass mat thermoplastic composites : Analysis of the mechanisms

Jan-Anders Edvin Maansson, Véronique Michaud, Joëlle Wolfrath

During reheating and post-processing of thermoplastic-based composites, deconsolidation is often observed: the volume fraction fibre decreases and the void content increases. In this article, the phenomena leading to deconsolidation are investigated, with ...

Carbon Fibre Reinforced Composite Waste: An Environmental Assessment Of Recycling, Energy Recovery And Landfilling

Jan-Anders Edvin Maansson, Véronique Michaud, Christian Ludwig, Robert Andrew Witik

The environmental benefits of recycling are assessed against other end-of-life (EOL) treatments for Carbon Fibre Reinforced Plastic (CFRP) waste. Recycling via pyrolysis, incineration with energy recovery, and disposal via landfilling are compared. To acco ...

Stitched shape memory alloy wires enhance damage recovery in self-healing fibre-reinforced polymer composites

Véronique Michaud, Amaël Maximilien Cohades, Nathan Klaus Hostettler

A major issue in composite technology is matrix micro-cracking due to low-velocity impact damage, which may severely limit service lifetimes of composite parts. In a novel approach, remarkable levels of healing of impact damage are obtained using shape mem ...

Design of Self-Healing Supramolecular Rubbers with a Tunable Number of Chemical Cross-Links

Véronique Michaud, Federica Sordo

Supramolecular rubbers incorporating a large number of physical cross-links through cooperative hydrogen bonds display high self-healing properties but limited solvent and creep resistance due to the lack of chemical cross-links. Increasing both chemical c ...

UV-intensity, temperature and dark-curing effects in cationic photo-polymerization of a cycloaliphatic epoxy resin

Jan-Anders Edvin Maansson, Véronique Michaud, Yves Leterrier, Basile Golaz

A difunctional cycloaliphatic epoxy monomer was cationically photo-polymerized in the presence of a diaryliodonium salt photoinitiator and an isopropyl thioxanthone photosensitizer at different temperatures and UV intensities. The photo-polymerization kine ...

Impact properties of shear thickening fluid impregnated foams

Véronique Michaud, Mathieu Soutrenon

Concentrated colloidal suspensions of silica particles in polyethylene glycol exhibit a shear thickening behavior: above a critical shear rate in a confined environment, they show a steep increase of viscosity. This reversible transition from a low to a hi ...
