Laitiers (métallurgie)En sidérurgie, le laitier est un coproduit de la métallurgie contenant des oxydes métalliques, essentiellement des silicates, des aluminates et de la chaux, qui sont formés en cours de fusion ou d'élaboration de métaux par voie liquide.
Il est issu de la fabrication de la fonte au haut fourneau, où il correspond à la gangue stérile du minerai de fer, isolée de la fonte liquide dont il se sépare par différence de densité.
La quantité de laitier produite correspond directement à la richesse du minerai de fer utilisé.
De composition chimique très stable, est souvent valorisé dans la fabrication de ciment (BFS-OPC) et dans les travaux publics (ballast, enrobé bitumé,...).

RhéologieIndex. décimale : 668.4 Plastiques, vinyles Résumé : In the current study, an assessment of the melt-compounding approach upon the behavior of blast furnace slag (BFS) filled polypropylene (PP) is reported. Two melt-compounding technologies are compared in terms of thermodynamic considerations as well as final behavior of the produced compounds. For this comparison, three PP-BFS formulations are introduced, where non-treated BFS is melt-mixed with PP via (1) internal lab mixer (IM) and (2) co-rotating twin-screw compounder (TSC). PP-BFS compounds from both processes are formed into plates via compression molding, characterized and tested for rheological, thermal and mechanical behavior. Processing parameters were evaluated for both processes such as specific shear work, residence time and shear rates. In addition, the rheological, thermal and mechanical behavior of comparable compounds are evaluated. The calculated specific shear work values for IM and TSC are 0.15 and 0.1 kW · h · kg?1. Calculated residence time for TSC is 55 s. Regarding the rheological behavior, it was found that melt mixing via both technologies did not show major differences in complex viscosity or storage- and loss moduli values. DSC findings show that crystallization and melting temperatures of IM- and TSC formulations are comparable. Decreased strain values are noticed for TSC compounds, while tensile modulus is found to be independent of process variation.

Moulage par transfert de résine sous videIndex. décimale : 668.4 Plastiques, vinyles Résumé : Whether a vehicle manufacturer is trying to reduce emissions or improve fuel efficiency, one of the most effective strategies is weight reduction and very few would dispute the fact that epoxy composites provide the best solution, offering a strength-per-weight ratio which is superior to any other materials. Historically, the industry struggled to act on that knowledge in a significant way due to being presented with a three-way challenge involving cycle time, cost and availability.
Huntsman Advanced Materials is focused on developing innovative materials for composites that meet the constantly evolving needs of the automotive sector. As the latest advancements in HP-RTM and compression molding show, composite structures can now be made at a cost, speed and quality, which is conducive to high-volume auto production.Note de contenu : - Liquid processes in automotive

Traction (mécanique)Index. décimale : 668.4 Plastiques, vinyles Résumé : Poly(β-hydroxybutyrate)-co-poly(β-hydroxyvalerate) (PHBV) loaded with 1 to 10 wt.% of cork microparticles (CM) were manufactured via compression molding technique. CM were isolated by alkali, bleaching and acid hydrolysis treatments. They were then added to the PHBV matrices via solution casting technique. The filler microparticles showed typical diameters of 10 to 55 μm. Mechanical tests in tension showed that in PHBV containing 5 wt.% CM the Young's modulus and the tensile strength increased by 50% and 10% respectively. Meanwhile, the elongation at break decreased by 70% for the same CM content. The mechanical behavior of the reinforced composites was discussed in conjunction with the morphology of the samples studied by optical and electron microscopy. The temperature of initial degradation Tid, the temperature at 5% weight loss Td5% and the temperature of maximum degradation Tdmax increase with increasing CM content by up to 13.6°C, 10.1°C and 12.3°C respectively for the composite of 5 wt.%. The composite with 10 wt.% CM content showed the best thermal stability with temperature increments of 20°C, 14.1°C and 21.5°C respectively. DSC results showed that the presence of CM has a very weak influence on the melting/crystallization behavior of the composites.

ThermodurcissablesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Polymer matrix composites are finding increasing number of applications due to their high weight-saving potential as well as unique characteristics, such as high strength-to-density ratio, fatigue resistance, high damping factor, and freedom from corrosion. While many textbooks are available on the mechanics of polymer matrix composites, few cover their processing. Processing of Polymer Matrix Composites fills this gap. The book focuses on the major manufacturing processes used for polymer matrix composites and describes process details, process parameters and their effects on properties and process-induced defects, and analytical and experimental methods used for understanding process conditions. The book describes fibers, thermosetting and thermoplastic polymers, and interface characteristics that are important from the standpoint of both design and processing. It also emphasizes the applications of process fundamentals for both continuous fiber and short fiber polymer matrix composites. In addition the book considers quality inspection methods, tooling, and manufacturing costs and environmental and safety issues. Note de contenu : 1. INTRODUCTION : 1. Constituents – 2.
