Spun fibres: a quasi circularly birefringent medium

Luc Thévenaz, Ana Gabriela Correa Mena, Xu Cheng

A simplified model describing the polarisation characteristics of spun fibres is proposed, aiming at determining how close to a circularly birefringent medium such a fibre is. This is of crucial importance regarding the interest of such a medium for magnet ...

Mode I interlaminar fracture of carbon epoxy laminates: Effects of ply thickness

John Botsis, Joël Cugnoni, Thomas Gmür, Guillaume Frossard

In this work, the influence of ply thickness on strain energy release rate (ERR) in delamination of carbon epoxy laminates is addressed. Specimens with three ply thicknesses: 0.030, 0.075 and 0.150 mm are tested. While the ERR at onset of crack propagation ...

Dynamic mechanical properties of epoxy/flax fibre composites

Pierre-Etienne Bourban, Fabien Duc

The mechanical and damping properties were measured for unidirectional, 0/90 and twill 2/2 flax fibre (FF) composites containing 40 vol% of fibres in an epoxy matrix. All composites were processed by resin transfer moulding. The influence of the impregnati ...

Thin ply composites: Experimental characterization and modeling of size-effects

John Botsis, Joël Cugnoni, Robin Amacher, Larissa Sorensen

Thin-ply composites are rapidly gaining interest in the composite industry, not only because of the larger design possibilities that they offer, but also because of positive size effects that have been shown to improve performance in various loading condit ...
