Self stratifying coating : A review / Sudip Nath in PAINTINDIA, Vol. LII, N° 10 (10/2002)
[article]
Titre : Self stratifying coating : A review Type de document : texte imprimé Auteurs : Sudip Nath, Auteur Année de publication : 2002 Article en page(s) : p. 31-40 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Autostratification 'Article synthèse' 'Revêtement multicouche' Stratification 'Formation film' Peinture 'Matériau revêtement' Index. décimale : 667.9 Revêtements et enduits Résumé : In this paper, recent advances in coating industries namely self-stratifying coating has been discussed from mechanistic point of view. After application as thinned film, self stratifying coating does spontaneously form two coherent layers as base coat/clear coat, primer/top coat in one single operation. The necessary requirements for this type of coating have been discussed in detail, including compatibility between the resins, surface energies and other parameters. Stratification can be predicted from the extent of overlaping of solubility spheres using Hansen solubility parameters (HSP) and surface energies. Various factors like evaporation rate, viscosity, film thickness and curing rate effecting self stratifying coating have also been focused on. Very good stratification have been observed in epoxy/acrylic, epoxy vinylether copolymer and epoxy/floro ethelene in their unpigmented systems. Success have also been achieved to locate a protective pigment in the primer and subsequent clear over it. Good stratification were also formulated with the adhesion promote silane coated rutile, where protective pigment was located in the primer layer while rutile in top-coat.

Titre : Bespoke simulation tool for thermoplastic composite Type de document : texte imprimé Auteurs : Muhammad Amir Khan, Auteur ; Ralf Schledjewski, Auteur Année de publication : 2010 Article en page(s) : p. 53-55 Langues : Anglais (eng) Tags : 'Vérification expérimentale' 'Simulation numérique' Stratification 'Procédé fabrication' Stratifié 'Matériau renforcé fibre' composite' Thermoplastique Index. décimale : 668.4 Plastiques, vinyles Résumé : Manufacturing with fibre-reinforced thermoplastic materials is challenging and often requires expensive experimental testing. The Institut für Verbundwerkstoffe focused its attention on the complete understanding, explanation and simulation of each manufacturing technique using thermoplastics. These efforts resulted in the theoretical description of processes, updating of existing mathematical models, and development of customized simulation tools.

The moulds have an extra-hard nickel surface that allows moulding many times more than with one made of composite materials. This technology is particularly well-suited for RTM processes and prepreg moulding. Note de contenu : - A BRIEF HISTORY OF THE TECHNOLOGY

Horizon Yachts subsidiary ATech Composites is the first SCRIMPTM licensee in Taiwan. ATech has been applying infusion technology to all sizes of hulls, decks and superstructures for the past five years. Today, the infused resin flow is easily controlled in three dimensions to wet through hulls as long as 130 feet. Single-skin or sandwich shell plates andthe main longitudinal and transverse structures are infused in one shot. Here, we present several successful cases for lengths from 48 feet to 130 feet.
