High dry friction requires intimate contact between two surfaces and is generally obtained using soft materials with an elastic modulus less than 10 MPa. We demonstrate that high-friction properties similar to rubberlike materials can also be obtained usin ...
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. ...
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 ...
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 ...
Nanoimprint lithography (NIL) is an emerging patterning technology which shows the capability of fabricating nanostructures on a large scale. It is therefore interesting for low-cost NEMS manufacturing. As schematically shown, a stamp made of single crysta ...
The repetitive discoloration kinetics of the azo-dye Methyl Orange (taken as a model organic compound) was followed under solar simulated radiation (90 mW/cm2) to assess the performance of the TiO2/Tedlar® composite photocatalyst. The influence of solution ...
The present PhD thesis deals with the high temperature polymerization of methyl methacrylate in a continuous pilot scale process. The major aim is to investigate the feasibility of a polymerization process for the production of PMMA molding compound at tem ...
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 ...
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 ...
Oxygen permeability through the tubular La0.7Ca0.3Fe0.85 Co0.15O3-δ perovskite membrane prepared by thermoplastic extrusion was measured in the temperature range from 800° to 1040°C in an air/argon gradient, and compared with the oxygen permeability of pla ...
