Influence of the mould thermal expansion on composite stress build-up during curing

Véronique Michaud, Sébastien Lavanchy

The influence of the mould material on the build-up of internal stresses during autoclave cure of a unidirectional carbon fibre composite material was investigated using embedded optical fibre Bragg gratings. Four flat moulds (i.e. aluminium, steel, carbon ...

Reaction-Induced Phase Separation in Poly(vinyl acetate)/ Polyester Blend

Xavier Bulliard, Véronique Michaud

In blends of unsaturated polyester (UP), poly (vinyl acetate) (PVAc), and styrene, a reaction-induced phase separation occurs upon curing that is due to the crosslinking between styrene and the UP molecules. The evolution of the morphology was observed by ...

Dynamic properties of sandwich structures with integrated shear-thickening fluids

Pierre-Etienne Bourban, John Christopher Plummer, Véronique Michaud, Christian Fischer, Sylvia Aviva Braun

The integration of shear-thickening fluids (STFs) into composite structures has been investigated with the aim of tuning part stiffness and damping capacity under dynamic deformation. Results from oscillatory rheological measurements for a STF based on con ...

Dynamic capillary effects in liquid composite moulding with non-crimp fabrics

Véronique Michaud

A technique is presented to measure the capillary pressure drop DPg during infiltration of non-crimp fabrics by a liquid matrix. Three types of liquids are used: polyethylene glycol (PEG) dissolved in water, a thermoset epoxy resin and a reactive thermopla ...

In situ strain and temperature monitoring of adaptive composite material

Hans Georg Limberger, René Salathé, Véronique Michaud

An optical fiber sensor is designed to simultaneously measure strain and temperature in an adaptive composite material. The sensor is formed by splicing two fiber Bragg gratings (FBGs) close to each other, which are written in optical fibers with different ...

Void Formation And Transport During SMC Manufacturing: Effect Of The Glass Fibre Sizing

Véronique Michaud, Emmanuelle Comte

The present study investigates the origin of voids in sheet molding compounds (SMCs) sheets and their transport during the manufacturing steps. Paste mixing, impregnation, thickening, and molding have been performed with five different SMC sheets, one with ...

Low-Profile mechanisms in a PVAc/polyester blend

Xavier Bulliard, Véronique Michaud

The different steps associated with the curing of a PVAc/polyester blend are identified and correlated to the mechanism of shrinkage control in the presence of a low-profile additive (LPA). Poly(vinyl acetate) (PVAc) is used as a LPA and is shown to induce ...

Manufacturing cost comparison of thermoplastic and thermoset RTM for an automotive floor pan

Véronique Michaud, Martyn Douglas Wakeman

Two resin transfer moulding (RTM) processes have been examined for automotive body-in-white (BIW) structures. An epoxy system was compared with a novel reactive polyamide 12 (PA12) system via characterisation of reaction kinetics and the production of carb ...

Interlaminar fracture toughness improvement in composites with hyperbranched polymer modified resin

Véronique Michaud

The present work aims to enhance the interlaminar toughness of carbon/epoxy composites produced by RTM by modifying the resin with hyperbranched polymers (HBPs). A HBP content of 7.5% in the resin was selected as the best compromise between a slight loss i ...

Correlation between sizing formulation and compressive behaviour of concentrated glass bundle suspensions

Véronique Michaud, Emmanuelle Comte

The correlation between sizing formulation, bundle mechanical characteristics, and bundle-matrix static and dynamic interactions are investigated. Two glass-fiber sizing formulations are considered, one containing polyvinyl acetate (PVAc) and the other pol ...

Deconsolidation in glass mat thermoplastic composites : Analysis of the mechanisms

Véronique Michaud

During reheating and post-processing of thermoplastic-based composites, deconsolidation is often observed: the volume fraction fibre decreases and the void content increases. In this article, the phenomena leading to deconsolidation are investigated, with ...
