Liquid Ropes: A Geometrical Model for Thin Viscous Jet Instabilities

Pierre-Thomas Paul Brun

Thin, viscous fluid threads falling onto a moving belt behave in a way reminiscent of a sewing machine, generating a rich variety of periodic stitchlike patterns including meanders, W patterns, alternating loops, and translated coiling. These patterns form ...

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 ...

Novel technique for distributed fibre sensing based on faint long gratings (FLOGs)

Luc Thévenaz, Sang Hoon Chin

A novel approach for fibre distributed sensing is proposed, conceived to match as closely as possible to an ideally responding distributed sensor. It is demonstrated that it can be actually realized using fibre Bragg gratings of extremely low index contras ...

Effect of annealing and silylation on the strength of melt-spun Ni-Mn-Ga fibres and their adhesion to epoxy

Véronique Michaud, Yves Leterrier, Susanne Glock, Edgars Sparnins

Single crystals of ferromagnetic Ni-Mn-Ga shape memory alloys show magnetic-field and stress induced twinning, leading to shape memory. Adaptive composites can thus be produced by embedding single crystalline particles or bamboo-structured Ni-Mn-Ga fibres ...

The role of twist and crimp on the vibration behaviour of flax fibre composites

Pierre-Etienne Bourban, Fabien Duc

The damping properties of unidirectional, 0/90 and twill 2/2 flax fibre (FF) reinforced epoxy composites containing 40 vol% of fibres have been measured by vibration beam testing (VBT). The influence of the impregnation quality, the fibre/matrix adhesion, ...

Form finding of twisted interlaced structures: a hybrid approach

Yves Weinand, Seyed Sina Nabaei, Olivier Baverel

Our study presents a set of form-finding procedures to explore curved structures made from interlaced panels. Interlacing introduces a particular coupling between assembly components which has to be formulated along with a pertinent flexible body model. We ...

Damping of thermoset and thermoplastic flax fibre composites

Pierre-Etienne Bourban, John Christopher Plummer, Fabien Duc

The mechanical and damping properties of unidirectional (UD) and twill 2/2 flax fibre (FF) reinforced thermoset (epoxy) and thermoplastic (polypropylene (PP) and polylactic acid (PLA)) composites containing 40 vol% of fibres have been compared with those o ...

Arrested fluid-fluid phase separation in depletion systems: Implications of the characteristic length on gel formation and rheology

Suliana Manley

We investigate the structural, dynamical, and rheological properties of colloid-polymer mixtures in a volume fraction range of φ=0.15-0.35. Our systems are density-matched, residual charges are screened, and the polymer-colloid size ratio is ∼0.37. For the ...

Kink instability of flux ropes anchored at one end and free at the other

Ivo Furno

The kink instability of a magnetized plasma column (flux rope) is a fundamental process observed in laboratory and in natural plasmas. Previous theoretical, experimental, and observational work has focused either on the case of periodic (infinite) ropes (r ...
