Studies of mode I delamination in monotonic and fatigue loading using FBG wavelength multiplexing and numerical analysis

Bridging by intact fibers in composite materials is one of the most important toughening mechanisms. However, a direct experimental assessment of its contribution is not easy to achieve. In this work a semi-experimental method is proposed to quantify its c ...

Impact localisation with FBG for a self-healing carbon fibre composite structure

Véronique Michaud, Eva Kirkby

We demonstrated the localisation of impacts in orthotropic carbon fibre reinforced polymer (CFRP) composite materials to within a few centimetres, using a sparse array of fibre Bragg grating (FBG) sensors. This type of sensor is easily embedded in composit ...

Influence of SiC reinforcement particles on the tribocorrosion behaviour of Al-SiCp FGMs in 0.05M NaCl solution

Stefano Mischler

The main aim of this work was to study and understand the influence of SiC particles on the corrosion and tribocorrosion of Al-matrix composite materials. For that, Al-SiCp functionally graded composites were produced by centrifugal casting and different S ...

Non-autoclave processing of honeycomb sandwich structures: Skin through thickness air permeability during cure

Véronique Michaud

In non-autoclave processing of sandwich structures, the pressure level inside the honeycomb becomes a critical process parameter, which depends on the permeability to air of the upper skin. In this work, prepreg and adhesive permeabilities were determined ...

Shear wrinkling of GFRP webs in cell-core sanwiches

Thomas Keller, Anastasios Vassilopoulos, Behzad Dehghan Manshadi

Glass fiber-reinforced (GFRP) cell-core sandwich structures are increasingly used in bridge deck and roof construction. GFRP cell-core sandwiches are composed of the outer GFRP face sheets, a foam core and a grid of GFRP webs integrated into the core in or ...

Piecewise non-linear constant life diagram formulation for FRP composite materials

Thomas Keller, Anastasios Vassilopoulos, Behzad Dehghan Manshadi

A new formulation for predicting an asymmetric, piecewise non-linear constant life diagram (CLD) is introduced in this paper. The development of the new model is based on the representation of the fatigue data on the stress ratio (R)-stress amplitude (σa) ...

Structural damping of model sandwich structures using tailored shear thickening fluid compositions

Véronique Michaud, Christian Fischer

Shear thickening fluids (STF) demonstrate the ability to simultaneously stiffen and increase their damping capacity above a critical shear strain, which depends on the particle concentration and aspect ratio in the STF. The present work considers two types ...

High-speed internal strain measurements in composite structures under dynamic load using embedded FBG sensors

John Botsis, Joël Cugnoni, Dragan Coric, Jeannot Frieden

Internal strain measurements in cross-ply carbon-epoxy composite plates under dynamic loads are carried out using embedded FBG sensors. The principle of the FBG interrogation is based on intensity demodulation achieved via a Fabry-Perot filter. To account ...

Experimental investigation of the temperature effect on the structural response of SG-laminated reinforced glass beams

Pieter Christian Louter

To generate high-level redundancy for structural glass beams, a novel concept of laminating a metal reinforcement to a structural glass beam has been developed at Delft University of Technology (TU Delft). This concept makes use of the relatively stiff pol ...

Dynamic analysis of laminated composite plates traversed by a moving mass based on a first-order theory

Elyas Ghafoori

The dynamic response of angle-ply laminated composite plates traversed by a moving mass or a moving force is investigated. For this purpose, a finite element method based on the first-order shear deformation theory is used. Stationary and adaptive mesh tec ...
