[article]  inJEC COMPOSITES MAGAZINE > N° 100 (10/2015) . - p. 49-51 Titre : Reduction of cure cycle time through microwave curing : a vision for the near future Type de document : texte imprimé Auteurs : Daniel Teufl, Auteur ; Elisabeth Ladstätter, Auteur ; Klaus Drechsler, Auteur Année de publication : 2015 Article en page(s) : p. 49-51 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Composites Economies d'énergie Epoxydes Micro-ondes Réticulation (polymérisation) Temps de cycle (production) -- Réduction Index. décimale : 668.4 Plastiques, vinyles Résumé : Microwave curing has a huge potential to reduce the cycle time of heating processes in composite manufarturing. It also significantly reduces energy consumption. In theory and in special applications, such as the cure of filament-wound parts and flat panels, this benefit can already be shown. Thinking further, the possibilities of microwave heating are diverse. With snap-curing resins, for example, the high heat-up ramps possible in microwave applicators could be used to cure a part in minutes at high temperature after an infiltration lasting several hours. While this may be a special scenario of interest for large and thick parts, new ways of manufarturing will occur according to needs and possibili-ties. Microwave heating, at all events, is a huge opportunity in heti.
