Damage-driven strain localisation in networks of fibres: A computational homogenisation approach

Pablo Antolin Sanchez, Felipe Figueredo Rocha

In many applications, such as textiles, fibreglass, paper and several kinds of biological fibrous tissues, the main load-bearing constituents at the micro-scale are arranged as a fibre network. In these materials, rupture is usually driven by micro-mechani ...

Composite material

Véronique Michaud, Amaël Maximilien Cohades

In a composite material (6), comprising a fibrous reinforcement (3), and a polymer matrix (14), wherein the polymer matrix (14) comprises two interpenetrating phases, namely a thermoset phase and a continuous thermoplastic phase, wherein the thermoset phas ...

Mechanical properties of natural fiber composites produced using dynamic sheet former

Composites formed from wood fibers and man-made cellulosic fibers in PLA (polylactic acid) matrix, manufactured using sheet forming technique and hot pressing, are studied. The composites have very low density (due to high porosity) and rather good elastic ...

Multiscale experimental characterisation and modelling of transverse cracking in thin-ply composites

Sébastien Kohler

In this work, the damage dependency on ply thickness is investigated experimentally for three different thin-ply CFRP quasi-isotropic laminates, with constituents spanning a large range of properties. It is shown that free edge damage mechanisms, observed ...

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 ...

Assessment of capillary phenomena in liquid composite molding

Véronique Michaud, Baris Çaglar, Feyza Karasu Kiliç, Cem Tekin

The interplay between capillary and viscous forces plays a significant role for optimal part quality in fiber-reinforced composites manufactured by Liquid Composite Molding (LCM); these are however difficult to analyze during flow. Two approaches are propo ...

Two-dimensional crack growth in FRP laminates and sandwich panels

Aida Cameselle Molares

Fiber-reinforced polymer (FRP) composite materials are currently being selected for the design of lightweight and efficient structural members in a wide number of engineering applications. Sandwich panels with glass fiber-reinforced polymer (GFRP) face she ...

Load history effects in fibre-reinforced polymer composite materials

Abdolvahid Movahedirad

Today, it is widely accepted that fatigue is one of the most common failure mechanisms in structural components, and pure static failure is rarely observed. Engineering structures are subjected to complex mechanical fatigue loading histories, which cause d ...

Size limitations on achieving tough and healable fibre reinforced composites through the use of thermoplastic nanofibres

Véronique Michaud, Amaël Maximilien Cohades, Lode Geeraard Daelemans

Phase-separated blends of epoxy and poly(ε-caprolactone) (PCL) provide crack repair in composites after a thermal treatment at 150 °C, but decrease the material’s fracture toughness. This article investigates the combination of healing with interlaminar fr ...

Stitched shape memory alloy wires enhance damage recovery in self-healing fibre-reinforced polymer composites

Véronique Michaud, Amaël Maximilien Cohades, Nathan Klaus Hostettler

A major issue in composite technology is matrix micro-cracking due to low-velocity impact damage, which may severely limit service lifetimes of composite parts. In a novel approach, remarkable levels of healing of impact damage are obtained using shape mem ...
