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 ...

Strategies for faster impregnation in melt thermoplastic resin transfer molding process

Damiano Salvatori

Continuous fiber thermoplastic composites are potential substitutes of steel in structural automotive components, since they combine fiber strength and rigidity with ductility, potential recyclability and low density of the thermoplastic (TP) matrix. Resin ...

Organic-Inorganic Hybrid Planarization and Water Vapor Barrier Coatings on Cellulose Nanofibrils Substrates

Yves Leterrier, Feyza Karasu Kiliç

Cellulose nanofibrils (CNF) can be produced in the form of thin, transparent and flexible films. However, the permeability of such materials to oxygen and water vapor is very sensitive to moisture, which limits their potential for a variety of packaging an ...

Functional composites with damage control and repair

Amaël Maximilien Cohades

Fibre Reinforced Polymer (FRP) composite structures are subjected during service to low energy impacts or unexpected loads, leading to damage. Microcracks are generally first formed in the matrix and can reach up to several hundred microns in thickness. In ...

Ductile adhesively-bonded timber joints - Part 1: Experimental investigation

Thomas Keller, Anastasios Vassilopoulos, Myrsini Angelidi

In the field of timber load-bearing structures, adhesive bonding is a promising joining technique that may increase the structural stiffness and capacity of timber joints and structures. The use of ductile adhesives may furthermore allow designing ductile ...

Feasibility of accelerated curing for strengthening of steel members by prestressed bonded CFRP plates

Ardalan Hosseini, Elyas Ghafoori

Bond behavior and anchorage resistance of prestressed CFRP plates to steel substrate have been investigated in the current study. To do so, a set of single lap-shear and prestress release tests was performed on CFRP-to-steel bonded joints, and the feasibil ...

Thermo-mechanical stability of lightweight glass-free photovoltaic modules based on a composite substrate

Christophe Ballif, Alessandro Francesco Aldo Virtuani, Hengyu Li, Laure-Emmanuelle Perret Aebi, Valentin Chapuis, Ana Cristina Oliveira Martins

Lightweight PV modules are attractive for building-integrated photovoltaic (BIPV) applications, especially for renovated buildings, where the additional load bearing capacity is limited. This work focuses on the development of a lightweight, glass-free pho ...

Effects of load interruption on the fatigue life of GFRP composites

Thomas Keller, Anastasios Vassilopoulos, Abdolvahid Movahedirad

The effect of cyclic loading interruption on the fatigue behavior of angle-ply (±45)2S glass/epoxy composite laminates was investigated by comparing the obtained results of continuous- and interrupted loading patterns. Continuous fatigue experiments were p ...

Short-term bond behavior and debonding capacity of prestressed CFRP composites to steel substrate

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

In this study, the short-term bonding behaviors of prestressed CFRP plates to steel substrates and their debonding capacities have been investigated. For this purpose, single lap-shear and prestress release tests were performed on adhesively bonded CFRP-to ...
