Cellular composites based on continuous fibres and bioresorbable polymers

Pierre-Etienne Bourban

Biocompatible composites, whose porosity and fibre fraction call be tailored over a large range and whose mechanical resistance is comparable to that Of natural bone, were processed with poly(lactic acid) (PLA) and continuous glass fibres. The processing s ...

Human fetal bone cells associated with ceramic reinforced PLA scaffolds for tissue engineering

Dominique Pioletti, Pierre-Etienne Bourban, Corinne Scaletta, Lee Ann Laurent-Applegate, Claire Diane Delabarde

Fetal bone cells were shown to have an interesting potential for therapeutic use in bone tissue engineering due to their rapid growth rate and their ability to differentiate into mature osteoblasts in vitro. We describe hereafter their capability to promot ...

A composite biofoam, from research to in vivo validation

Dominique Pioletti, Pierre-Etienne Bourban

Bone tissue engineering aims at developing scaffolds, or porous structures, as supports for cell migration, proliferation and differentiation, in order to favor bone healing. L-poly lactic acid (PLA) foams, which were reinforced or not with β-tricalcium ph ...

Polylactic acid-phosphate glass composite foams as scaffolds for tissue engineering

Dominique Pioletti, Pierre-Etienne Bourban

Phosphate glass (PG) of the composition 0.46(CaO)-0.04(Na(2)O)- 0.5(P(2)O(5)) was used as filler in poly-L-lactic acid (PLA) foams developed as degradable scaffolds for bone tissue engineering. The effect of PG on PLA was assessed both in bulk and porous c ...

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

Pierre-Etienne Bourban, John Christopher Plummer, Véronique Michaud, 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 ...

What static and dynamic properties should slalom skis possess? Judgments by advanced and expert skiers

Pierre-Etienne Bourban, Christian Fischer, Michael Herzog, Olaf Blanke

Flexural and torsional rigidity are important properties of skis. However, the flexural and torsional rigidity that lead to optimal performance remain to be established. In the present study, four pairs of slalom skis that differed in flexural and torsiona ...

Processing of homogeneous ceramic/polymer blends for bioresorbable composites

Pierre-Etienne Bourban

Three methods to mix ceramic fillers, hydroxyapatite or β-tricalcium phosphate, with a polymer matrix, a poly l-lactic acid, are investigated as a first step prior to supercritical foaming to prepare porous composite structures for biomedical applications. ...

Dynamic Properties of Materials for Alpine Skis

Pierre-Etienne Bourban, John Christopher Plummer, Véronique Michaud, Christian Fischer, Etienne Combaz

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 ...

Stamp forming of carbon fibre/PA12 composites - a comparison of a reactive impregnation process and a commingled yarn system

Pierre-Etienne Bourban, Martyn Douglas Wakeman

Two forms of carbon fibre reinforced polyamide 12 (PA12) were compared during non-isothermal stamp forming. The first was a stretch broken commingled yarn woven into a fabric, studied at three initial preconsolidation levels. The second was produced by in ...

Architecture and properties of anisotropic polymer composite scaffolds for bone tissue engineering

Dominique Pioletti, Pierre-Etienne Bourban

Bone is a complex porous composite structure with specific characteristics such as viscoelasticity and anisotropy, both in morphology and mechanical properties. Bone defects are regularly filled with artificial tissue grafts, which should ideally have prop ...
