Measurements of AC Loss Evolution in ITER TF Conductors

AC loss in the Nb3Sn cable-in-conduit conductors (CICC) usually decreases after the conductor undergoes electromagnetic cycling. This can be attributed to the increase of inter-strand resistance due to the detachment of the strand-bonding during cyclic loa ...

Transverse cracking in the bulk and at the free edge of thin-ply composites: experiments and multiscale modelling

John Botsis, Robin Amacher, Joël Cugnoni, Sébastien Kohler

Thin-ply composites were shown to exhibit significantly delayed transverse cracking, but the linear onset of damage scaling with ply thickness reported by Amacher et al. (2014) did not correspond to the established LEFM based in situ strength model. This s ...

Kinetics of mixing-water repartition in UHPFRC paste and its effect on hydration and microstructural development

Eugen Brühwiler, Karen Scrivener, Emmanuel Denarié, Arnaud Charles Albert Muller, Mohammadhadi Kazemi Kamyab

The hydration of an ultra-high performance fibre reinforced concrete (UHPFRC) paste with a water to cement ratio of 0.18 was followed by proton nuclear magnetic resonance (1H NMR) alongside more classical techniques for hydration kinetics, and microstructu ...

Crushing and intrusion resistance improvement of aluminum beams by carbon/epoxy composite patches

Véronique Michaud, Baris Çaglar, Jonathan Friedli, Yann Albert Gérard Lebaupin, Mathieu Piccand

This study investigates the intrusion and crushing performance of hybrid fiber metal laminates based on aluminum and carbon fiber reinforced polymers, in comparison to reference aluminum parts, made from AA6451 or AA7075 automotive grade alloys. A first se ...

Towards aerospace grade thin-ply composites: Effect of ply thickness, fibre, matrix and interlayer toughening on strength and damage tolerance

John Botsis, Robin Amacher, Joël Cugnoni, Larissa Sorensen, Sébastien Kohler

Thin-ply composites represent a promising approach to further improve the performance of carbon fibre composite structures thanks to their ability to delay the onset of matrix cracking and delamination up to the point of fibre dominated failure. However, t ...

The influence of through-thickness reinforcement geometry and pattern on delamination of fiber-reinforced composites: Part II - Modeling

Véronique Michaud, John Botsis, Georgios Pappas

This article reports modeling techniques and results based on experimental Mode I characterization of a layered woven GFRP material with tufting reinforcement. Standard tuft and loop-less geometries are investigated on three different areal patterns to eva ...

Aramid/glass fiber-reinforced thermal break - thermal and structural performance

Thomas Keller, Julia De Castro San Roman Fest, Kyriaki Goulouti

Energetically weak points in thermally insulated building envelopes are formed by thermal breaks that are implemented to structurally connect external balconies to internal slabs. Current thermal breaks comprise stainless steel bars that penetrate the insu ...

Aramid/glass fiber-reinforced thermal break - Structural system performance

Thomas Keller, Julia De Castro San Roman Fest, Kyriaki Goulouti

Energetically critical points in thermally insulating building envelopes are caused by penetrations of building interior concrete slabs through the envelope insulation layers to create external balconies. A new highly insulating balcony thermal break eleme ...
