StatistiqueIndex. décimale : 608 Inventions et brevets Résumé : While people may be familiar with patents as a means of protecting industrial property, they are less aware that they constitute a goldmine of information to gain an overview of any given sector, with a different perspective from that of market studies — one which sheds light on both the evolution of patent applications in the chosen Technological area over time and the top countries and players. This paper presents a statistical patent analysis that focuses on the field of composite shaping from 2005 to the present [1], based on some 16,000 patents classified under IPC [2] Class 829C70/00 — Shaping composites, i.e. plastics material comprising rein forcements, fillers or preformed parts, e.g. inserts.

Achieving optimal performance in these materials requires an under-standing of how particle morphology affects film formation and stress development in the film. In this study, soft-core/hard-shell latex particles with different shell ratios, core and shell glass transition temperatures(Tgs), and particle sizes (63–177 nm) were synthesized using a two-stage emulsion polymerization. The film formation behavior of the composite particles was investigated with cryogenic scanning electron micro-scopy, atomic force microscopy, and measurements of the minimum film formation temperature (MFFT). Results show that film formation was enhanced for particles with thinner hard shells, smaller particle size, and a smaller difference in Tg between the core and shell polymers. For example, the MFFT decreased and the particle deformation increased for particles with thinner shells and smaller article sizes. Stress development during drying was characterized using a cantilever beam bending technique. A walled cantilever design was used to monitor stress development without the complication of a lateral drying front. The film formation behavior and stress development correlated well with practical paint properties like scrub resistance and gloss.

L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

StratifiésIndex. décimale : 667.9 Revêtements et enduits Résumé : Polymers and metals greatly differ in their deformation behaviour when they are conformed as laminate composites. Knowledge of the conformation of a polymer in the interface region is an important aspect in understanding the mechanism of adhesion in the composite.
Characterisation and performance evaluations of the metal-polymer protective substrates, composed of a steel plate coated with electrolytic chromium (ECCS) and surface-protected by a poly(ethyleneterephthalate) (PET) co-rolled layer, were carried out by SEM (scanning electron microscopy) and TEM (transmission electron microscopy). The chemical composition and morphology of the components that allow for good adhesion of the metal-polymer plate were studied at the interface. ATR (attenuated total reflection), FT-IR (Fourier transform-infrared) and confocal Raman spectroscopy were employed to analyse the structural changes of the PET coatings on the ECCS plates resulting from the manufacturing processes and mechanical stresses.DOI : 10.1007/BF02699615 En ligne : https://link.springer.com/content/pdf/10.1007/BF02699615.pdf Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=5396

Produits et matériaux recyclésIndex. décimale : 668.4 Plastiques, vinyles Résumé : The escalating environmental impact of non-biodegradable waste, particularly from discarded tires, necessitates innovative recycling strategies. This study explores the potential of incorporating pre-treated crumb rubber from waste tires into concrete mixtures as a sustainable alternative to traditional coarse aggregates. A comprehensive experimental investigation was conducted to evaluate the fresh-state properties, workability, and mechanical behavior of rubberized concrete. The study focused on varying proportions of pre-treated rubber particles, substituting 10%, 20%, 30%, and 40% of conventional coarse aggregates by volume. These rubber particles were treated with cement paste to enhance bonding strength within the composite material. Standard tests were employed to assess the properties of the rubberized concrete, including density, slump, and compressive strength. The findings reveal that the incorporation of recycled tire rubber as a partial aggregate replacement notably impacts the workability and mechanical properties of the concrete. However, this reduction is mitigated when a concrete superplasticizer is utilized. Furthermore, the research indicates a decrease in the failure load of rubberized concrete composite slabs, ranging from 15% to 58%, compared to those constructed with traditional aggregates. Additionally, a significant reduction in the initial cracking load was observed. These outcomes offer critical insights into the structural and mechanical implications of using pre-treated rubber particles in concrete. While the decrease in mechanical performance poses challenges, the study illuminates pathways for enhancing the sustainability of concrete through the innovative reuse of waste materials. This approach not only addresses environmental concerns but also opens new avenues for the development of more sustainable construction materials. Note de contenu : - Previous studies

ThermoplastiquesUne matière thermoplastique désigne une matière qui se ramollit (parfois on observe une fusion franche) d'une façon répétée lorsqu'elle est chauffée au-dessus d'une certaine température, mais qui, au-dessous, redevient dure. Une telle matière conservera donc toujours de manière réversible sa thermoplasticité initiale. Cette qualité rend le matériau thermoplastique potentiellement recyclable (après broyage). Cela implique que la matière ramollie ne soit pas thermiquement dégradée et que les contraintes mécaniques de cisaillement introduites par un procédé de mise en forme ne modifient pas la structure moléculaire.Index. décimale : 668.3 Adhésifs et produits semblables Résumé : The Ford bumper case illustrates the benefits of properly defining the durability requirements of the structurally bonded assembly at the beginning of the process. Over four million bumpers have been successfully bonded with zero failures. The Vanguard case illustrates how durability requirements continuously evolve over time. The use of polyester putties for deck to hull joints in fiberglass boats was state-of-the-art technology a decade ago. Yet what was acceptable a decade ago is considered sub-standard now. So, Vanguard Racing Sailboats reevaluated the durability requirements of their sailboats and found new toughened adhesives that greatly enhance the durability of their sailboats. As Chip Johns noted, the project was successful because they focused on the durability expectations of the finished product at the end of the process - and not the material costs of the adhesive up front.
