Graded glass mat reinforced polypropylene

Jan-Anders Edvin Maansson, Véronique Michaud, Joëlle Wolfrath

In the impregnation process, when pressure is applied, the dry fiber preform is first compressed and then unloads as the matrix flows within the pores. It has been shown earlier that for glass mat-reinforced thermoplastic (GMT) materials, the time to provi ...

Electrofragmentation modeling of conductive coatings on polymer substrates

Jan-Anders Edvin Maansson, Yves Leterrier, Luc Rougier, Judith Helen Waller

Damage occurring under tensile loading and the resulting increase of electrical resistance of indium-doped tin oxide and amorphous graphite coatings on various polymer substrates are investigated, using an electro-fragmentation method in situ in an optical ...

Kinetics Of Desorption Of Water, Ethanol, Ethyl Acetate, And Toluene From A Montmorillonite

Jan-Anders Edvin Maansson, John Christopher Plummer, Pascal Clausen

Desorption processes of low-molecular-weight compounds from the surface of smectites into the gas phase determine a number of processes, e.g. those involved in drug delivery and the release of herbicides. The desorption has not been investigated thoroughly ...

Phase separation at the fiber-matrix interface in composites based on a thermoplastic/polyester blend

Jan-Anders Edvin Maansson, Véronique Michaud, Xavier Bulliard

A study of the microstructure developing at the surface of glass fibers in a poly(vinyl acetate) (PVAc)/polyester blend is presented. Three different experimental methods are used: a technique based on the Wilhelmy method to measure the wettability of the ...

Design and fabrication of compositionally graded inorganic oxide thin films: Mechanical, optical and permeation characteristics

Jan-Anders Edvin Maansson, Yves Leterrier, Xavier Bulliard

Different types of inorganic oxide films composed of a chemical composition gradient single layer were designed, fabricated and characterized. Compositionally graded thin films were created by power-controlled co-sputtering of alumina (Al2O3) and silica (S ...

Thermo-hygro-mechanical behaviour of ultrathin multilayer composite materials for flexible display applications

Jan-Anders Edvin Maansson, Yves Leterrier

Flexible displays form complex structures joining together multiple layers of very various materials: metal or plastic flexible substrate, barrier and encapsulation layers, thin-films of transistor and optoelectronic devices. Residual stresses are inherent ...

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

Jan-Anders Edvin Maansson, 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 ...

Frequency dependent dielectric and mechanical behaviour of elastomers for actuator applications

Jan-Anders Edvin Maansson, Yves Leterrier, John Christopher Plummer, Frank Nüesch

The low frequency mechanical and dielectric behavior of three different elastomers has been investigated by dynamic mechanical analysis and dielectric spectroscopy, with the aim of accounting for the frequency dependence of the characteristics of the corre ...

Dynamic Properties of Materials for Alpine Skis

Jan-Anders Edvin Maansson, Véronique Michaud, Pierre-Etienne Bourban, John Christopher Plummer, Christian Fischer

The aim of the present research has been to quantify the influence of different materials on the global dynamic response of a ski. The properties of the individual constituent materials were characterized as a function of temperature and frequency using dy ...

Thermoviscoelastic anisotropic analysis of process induced residual stresses and dimensional stability in real polymer matrix composite components

Jan-Anders Edvin Maansson, Véronique Michaud

A design tool able to predict the residual stress state and dimensional stability of large complex shaped composite parts has been developed. It is based on a finite element model, using a three-dimensional anisotropic thermo-viscoelastic formulation. Asym ...

Cellular biocomposites from polylactide and microfibrillated cellulose

Jan-Anders Edvin Maansson, John Christopher Plummer, Pierre-Etienne Bourban, Razvan Cristian Neagu, Carole Boissard

This paper describes the production of "green" microfibrillated cellulose-reinforced polylactide cellular biocomposites using a wet mixing technique combined with super-critical carbon dioxide foaming. The effect of composition on the morphology, density a ...

Bioresorbable composites prepared by supercritical fluid foaming

Jan-Anders Edvin Maansson, Dominique Pioletti, Pierre-Etienne Bourban

Bone is a natural composite construct, with a gradient structure going from a loose interconnected cellular core to an outer dense wall, thus minimizing bone weight while keeping a high mechanical resistance. Due to this unique and complex structure, bone ...

Hybrid glass mat reinforced polypropylene-montmorillonite nanocomposites

Jan-Anders Edvin Maansson, Véronique Michaud, John Christopher Plummer, Sara Dalle Vacche, Chrystèle Houphouet-Boigny Favre

Although addition of montmorillonite (MMT) clay to isotactic polypropylene (iPP) results in large increases in the melt viscosity at low shear rates, satisfactory impregnation of glass mats is obtained with iPP/MMT under conditions typical of industrial pr ...

Wettability of Glass Fibers in Reactive Thermoplastic/Polyester Blends: Comparison between Compatible and Incompatible Thermoplastics

Jan-Anders Edvin Maansson, Véronique Michaud, Xavier Bulliard

The evolution of morphology of reactive thermoplastic/unsaturated polyester blends at the surface of glass fibers is investigated during curing. The study focuses on two different types of thermoplastics, incompatible and compatible respectively with the p ...

Pre- and Post-Transition Behavior of Shear Thickening Fluids in oscillating Shear

Jan-Anders Edvin Maansson, Véronique Michaud, Pierre-Etienne Bourban, John Christopher Plummer, Christian Fischer

The dynamic shear-thickening behavior of concentrated colloidal suspensions of fumed silica in polypropylene glycol has been investigated. Dynamic frequency sweeps showed that, for any given solids concentration, the complex viscosity at different imposed ...

Liquid CO2 processing of solid polylactide foam precursors

Jan-Anders Edvin Maansson, John Christopher Plummer, Yonghoon Yoon

Diffusion of CO2 in polylactide was modelled by assuming the diffusion coefficient to depend on CO2 concentration, c, according to D[c]=D[0]exp[Ac], where D[0] and A are empirical constants, with the aim of optimizing impregnation of nominally amorphous an ...

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

Jan-Anders Edvin Maansson, 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 ...
