Article
Existing copper-coated carbon fibers used in wire scanners to measure the transverse beam profile in the accelerators at CERN are approaching material limits. A new instrument design has showed that the main limitation now comes from the centerpiece of the instrument: the wire. Large amplitude vibrations increase the risk of failure during scans. N...

Hemp-based materials have been recently proposed as adsorbents for metals present in aqueous solutions using adsorption-oriented processes. This study aims to reveal the adsorption mechanism of materials prepared from hemp shives as co-products of the hemp industry, namely sodium carbonate-activated (SHI-C) and polycarboxylic agent-grafted (SHI-BTC...

Monitoring integrity of operating structures has become a crucial need in industrial applications while motivation for more sustainable materials pushes forward the development of natural fibre composites (NFC). The complexity and variability of their failure behaviour and mechanical properties still limit the exploitation of their full potential....

Hemp is a sustainable source of natural fibres that can contribute to meet the increasing demand for technical applications in the textile and the composite sectors. Continuous reinforcements can be produced using the existing flax machinery, initially developed for textile purposes. To achieve competitive and economically viable fibre yields and a...

The development of sustainable sandwich materials is needed in the transportation sector to address environmental concerns related to the production and operation of vehicles. In addition to biobased composite skins, alternatives to classic synthetic core materials must be found to reduce the ecological footprint of whole sandwich-structured compos...

Increasing the production of high-performance natural fibres that minimise their impact on the environment is a challenge that flax (Linum usitatissinum L.) cannot address alone. In flax traditional production territories, hemp (Cannabis sativa L.) can be a complementary source of high added value fibres if their yield of long line fibres can be ma...

When investigating materials to be utilized, attention inevitably focuses on their resistance over the service life. Despite the popularity of amorphous polymers, ranging from their applications in structural components to their ability to increase the toughness of biocomposites, the investigation of their short- to long-term resistance has been co...

FINEAU (2021–2024) is a trans-disciplinary research project involving French, Serbian, Italian, Portuguese and Romanian colleagues, a French agricultural cooperative and two surface-treatment industries, intending to propose chènevotte, a co-product of the hemp industry, as an adsorbent for the removal of pollutants from polycontaminated wastewater...
Article

Transparency is a crucial factor in developing functional and decorative thin films and coatings, but incorporation of nanoparticles into organic resins for improving their properties quite often makes them opaque. In this work, photophysical properties of epoxy/layered double hydroxide (LDH) nanocomposite coatings were correlated with the dispersi...

This paper investigates the influence of the stress level and hygrothermal conditions on the creep/recovery behaviour of three high-grade composites made of GreenPoxy and flax and hemp fibres. The results show that the levels of instantaneous, time-delayed and residual strains increase with the applied load and the severity of the environment. The...

The deformation behavior of solid polymers under isothermal, quasi-static loadings is investigated. A comprehensive test program consisting of tension, torsion, and combinations thereof was conducted on a polycarbonate polymer under both monotonic and long-term cyclic loadings. The effects of different loading modes, creep load conditions, mean str...

This work describes the physical and mechanical characterisation of unidirectional [0]12 and crossply [(0/90)3/0 " ]S flax fibre reinforced composites fabricated in autoclave using a prepreg flax tape impregnated with fire retardant epoxy polymer. Tensile, bending and impact properties are evaluated along the longitudinal and transverse fibre direc...
Article
Acoustic emission (AE) is a passive monitoring technique used for learning about the behaviour of an engineered system. The streaming obtained by continuously recording AE transient signals is treated by a four steps procedure: 1) The detection of salient AE signals by distinguishing noise against non-noise signals using wavelet denoising, 2) the s...

In this study, the potential of microporous 3D metal–organic framework (MOF) for curing epoxy resin has been discussed. First, MIL-101 (Cr), a chromium based MOF, was synthesized under hydrothermal condition and then characterized by using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) and thermogravimetric (TGA) measuremen...

This study focuses on the impact of different fabrication parameters (build orientation, layer thickness and post-curing time) on the mechanical properties of parts fabricated through projection stereolithography technology. A Titan 2 HR printer (Kudo3D Inc.©) was used to print the specimens. Three different resins have been investigated. Specimens...

Recent developments in the field of bio-based composite materials are mainly focused on the use of unidirectional reinforcements. The production of woven fabrics and required yarns or rovings is still complex for composite applications due to the finite length of plant fibers and to the high number of process parameters which can be tuned. This stu...

A number of constitutive models have been developed for solid polymers to describe the large deformation behavior. However, most of the existing models rely on a purely elastic or hyperelastic initial response when they are incapable of accurately predicting the cyclic stress-strain hysteresis loops. In this work, therefore, a compact cyclic viscoe...

Pour réduire leur empreinte environnementale, les industriels recherchent des matériaux renouvelables pouvant se substituer aux solutions pétrosourcées. De par leur faible densité et leurs propriétés mécaniques élevées, l'intérêt pour les matériaux composites à fibres végétales se fait grandissant. Cependant, le manque de données concernant le comp...

Even if the knowledge on the fatigue behaviour of plant fibre composites has increased steadily in the last few years, some issues still remain open at the present time. Such is the case, for instance, of the high-cycle fatigue strength. Actually, most of the fatigue studies available in the open literature to date are limited to a maximum of 1–2 m...

Natural fibres are used as an alternative to man-made fibres in fibre reinforced composite materials in a variety of applications due to their good specific strength and stiffness properties and limited environmental impact. However, contrary to man-made fibres, used in the form of continuous filaments, natural fibres are extracted from plants in w...

My work is focused on the determination of the fatigue life time on very thin wires under 300µm in diameter.
Project
Manufacturers of metal alloys and polymer materials are interested in the assurance of components lifetime, especially when the lifetime cannot be easily inspected or may lead to a catastrophe in service. Due to the costly and time-consuming testing of long-term fatigue life, which still suffers from its sensitivity to environmental conditions and previous operation histories, there is a need to develop approaches that can simulate tests well.
