Elegant surfaces with visible natural fibers / Nils Becker in KUNSTSTOFFE INTERNATIONAL, Vol. 108, N° 9 (09/2018)  

[article]  inKUNSTSTOFFE INTERNATIONAL > Vol. 108, N° 9 (09/2018) . - p. 71-73 Titre : Elegant surfaces with visible natural fibers : Natural fiber compression moldings with a luxury finish made with a new composite material press process Type de document : texte imprimé Auteurs : Nils Becker, Auteur ; Werner Klusmeier, Auteur Année de publication : 2018 Article en page(s) : p. 71-73 Langues : Anglais (eng) Catégories : Automobiles -- Décoration Automobiles -- Matériaux Composites à fibres naturelles Fibres naturelles Panneaux de fibres Polypropylène Stratifiés Index. décimale : 668.4 Plastiques, vinyles Résumé : The use of natural fiber-reinforced composite materials is currently gaining new impetus in the form of decoratively finished designs which retain a natural appearance. A newly developed finishing technology from Yanfeng Automotive Interiors (YFAI) makes natural fibers visible. Note de contenu : - Natural protagonists in automotive interior - Luxury class visible natural fiber decor - Natural fibers for an environmentally friendly lifestyle - Fig. : It does not always have to be just piano black: natural fibers in the visible area create a visual and haptic contrast to the multifunctional, high-tech interior - Fig. 1 : A decorative fleece and a laminate printed on the rear side are responsible for the colorful natural fiber surfaces. The door panel consists of three layers that are pressed together in a single-stage process - Fig. 2 : The natural materials are laminated with a protective film to ensure that the surfaces meet the demands made on them. The challenge in this process is the forming of all the materi-als at up to 200°C En ligne : https://drive.google.com/file/d/1TS1o2u0vG-QJKEeOIB7RawHyTD2qISX1/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=31188 [article]
