Polyamide 6Index. décimale : 668.4 Plastiques, vinyles Résumé : At this year’s Fakuma, Lanxess introduced a special modification of PA6 to cope with constant, pulsating stresses such as are encountered by components under the hood. The aim of this new polyamide development was to reproduce in PA6 one of the core properties of PA66, which for all intents and purposes is now no longer available. Note de contenu : - Successful fatigue tests
- Other grades soon to be launched on the market
- Fig. : In the Geely 4G 14T cylinder head cover, PA66 has already been replaced by PA6 (Dure-than BKV35H2.0). With Durethan Performance materials, other applica-tions could follow
- Fig. 1 : In the Wöhler fatigue test, a ram continually presses with a defined load onto a sample component. The aim of the materials development was to withstand more load cycles at the same load level
- Fig. 2 : The screening test is a fatigue test on standard tensile test specimens developed in-house by lanxess. In this test, Durethan BKV20PH2.0 achieves a considerably higher number of cycles under moderate loads than a standard polyamide 6 with 30% glass fiber contentEn ligne : https://drive.google.com/file/d/12Gblgm2v5esmvZst-zE1R-S3FtWu-Q_U/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=31427

Simulation par ordinateurIndex. décimale : 668.9 Polymères Résumé : High strength and toughness are of importance for composite plastics used as mechanical structure parts. How to provide general and engineering plastics with high performances is one of the critical challenges in advanced manufacturing. In the past decade, the phase dispersion, interfacial interaction, injection molding simulation and fracture behaviors of composite plastics were investigated systematically in our research group in order to simultaneously reinforce and toughen polymer matrix. Here, we review the progress and advances which have been made in the above items.

Traction (mécanique)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The surface properties of leather are critical factors that influence the aesthetic quality of the leather. Commonly, organoleptic properties are evaluated for leathers to ascertain the bulk properties such as compactness, smoothness, softness and general grain appearance. Though these parameters are very subjective, still these properties are essential for leather product manufacture. In the current research, we discuss the correlation between the surface parameters and sewability of the leathers. In our earlier studies, we discussed the influence of syntans and fatliquors on sewability. In aligning to a similar subject, the impact of surface properties has been evaluated through contact angle measurements and correlated with the sewability properties of the leather. From the spread ability measurements, it can be inferred that the sewability properties are better towards the surface of the leather, which is more hydrophilic. This result agrees that the fatliquoringof leathers has enhanced the stitch ability; moreover, the studies provide biophysical parameter importance for qualifying leather sewability.
