Sustainable polyesters via direct functionalization of lignocellulosic sugars

Yves Leterrier, Véronique Michaud, François Maréchal, Jeremy Luterbacher, Harm-Anton Klok, Graham Reid Dick, Adrien Julien Demongeot, Christèle Rayroud, Maxime Alexandre Clément Hedou, Thibault Rambert

The development of sustainable plastics from abundant renewable feedstocks has been limited by the complexity and efficiency of their production, as well as their lack of competitive material properties. Here we demonstrate the direct transformation of the ...

A Novel Method to Quantify Self-Healing Capabilities of Fiber-Reinforced Polymers

Véronique Michaud, Amaël Maximilien Cohades, Robin Samuel Trigueira, Cecilia Scazzoli

The present work investigates a novel and practical method to evaluate the healing efficiency of carbon-reinforced polymer composites. The method should be representative of damage occurring during the lifetime of a composite part, should tend to damage th ...

Fiber Buckling in Confined Viscous Flows: An Absolute Instability Described by the Linear Ginzburg-Landau Equation

François Gallaire, Jean Cappello

We explore the dynamics of a flexible fiber transported by a viscous flow in a Hele-Shaw cell of height comparable to the fiber height. We show that long fibers aligned with the flow experience a buckling instability. Competition between viscous and elasti ...

Characterization of shear deformations in reinforced concrete members without shear reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone, Andri Setiawan

The load-carrying capacity of many reinforced concrete structures is governed by shear failures, occurring before reaching the flexural capacity of the member. For redundant systems, such as slabs subjected to concentrated loads, local shear failures (typi ...

Seismic events miss important kinematically governed grain scale mechanisms during shear failure of porous rock

Edward Carlo Giorgio Andò

Catastrophic failure in brittle, porous materials initiates when smaller-scale fractures localise along an emergent fault zone in a transition from stable crack growth to dynamic rupture. Due to the rapid nature of this critical transition, the precise mic ...

Multi-scale experimental testing on variable stiffness and damping components for semi-active structural control

Gennaro Senatore

This paper presents experimental testing of a new semi-active vibration control device comprising a shape memory polymer (SMP) core that is reinforced by an SMP-aramid composite skin. This control device works as a load-transfer component that can be integ ...

Flexural behaviour of post-tensioned glass beams: Experimental and analytical study of three beam typologies

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

The concept of post-tensioned glass beams builds on the concrete analogy of the reinforced glass beams. By additionally prestressing the reinforcement in a post-tensioned system, a compressive pre-stress is applied on the glass, enhancing the initial fract ...

Kinematic and mechanical response of dry woven fabrics in through-thickness compression: Virtual fiber modeling with mesh overlay technique and experimental validation

Véronique Michaud, Baris Çaglar, Lode Geeraard Daelemans

The through-thickness compressive behavior of fabric reinforcements is crucial in liquid composite molding manufacturing processes. Predictive simulations of the compressive response are thus necessary to enable a virtual processing workflow. These are com ...

Soft functional fibers for mechanical sensing and actuation

Andreas Leber

The measurement and generation of mechanical deformations is a key functionality in health monitoring, human-machine interaction, and soft robotics. However, current methods typically rely on small and hard transducers, which result in poor performance, cu ...

Functionalized Fiber Reinforced Composites via Thermally Drawn Multifunctional Fiber Sensors

Véronique Michaud, Dang Tùng Nguyen, Fabien Sorin, Stella Andréa Françoise Laperrousaz, Baris Çaglar, William Nicolas Duncan Esposito

Monitoring fiber reinforced polymer composites (FRPC) during their production and operation is becoming crucial to track the performance of the final parts and optimize the overall life cycle. The challenges associated with integrating multifunctional sens ...
