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 ...

Hierarchical porous structure

Dominique Pioletti, Pierre-Etienne Bourban, Matteo Gregorio Modesto Marascio

Cellular thermoplastic structures with hierarchical multi-scale porosity (preferably 1-300 µm micro-porosity to 0.3-10 mm macro-porosity) are produced from an integrated approach of 3D printing, preferably by Fused Deposition Modeling (FDM), and of supercr ...

Occurrence of the Portevin Le-Chatelier effect in open-cell microcellular Al-2 wt% Mg

Andreas Mortensen, Kseniya Illkova

Microcellular open-cell metal foams with pores of 75 or 400 pm in diameter and made of pure Al or Al-2 wt% Mg are tested in compression. The aluminum foam exhibits a typical smooth plastic flow and a positive strain rate sensitivity, whereas plastic instab ...

All natural cork composites with suberin-based polyester and lignocellulosic residue

Véronique Michaud, Hugo De Oliveira

Suberin is an aromatic-aliphatic cross-linked polyester structure which constitutes cell wall structures of cork. It is particularly interesting for its use of monomeric compounds towards renewable bio-based polymers. In this study, the extraction of suber ...

Long-term design of FRP-PUR web-core sandwich structures in building construction

Thomas Keller, Julia De Castro San Roman Fest, Sonia Yanes Armas

The structural behavior of GFRP-polyurethane (PUR) web-core sandwich structures subjected to sustained loading was investigated. As a basis, a study of the mechanical behavior of rigid PUR foams used as core materials was conducted, with emphasis on creep. ...
