Title
(EN) PREPREG FOR DECORATIVE COMPONENTS WHICH ARE HIGHLY HEAT-RESISTANT, TRANSPARENT, COLORLESS AND FREE OF DEFECTS, SUCH AS SPOTS AND DOTS, AND MANUFACTURING METHOD THEREOF
(FR) PRÉIMPRÉGNÉ POUR ÉLÉMENTS DÉCORATIFS QUI SONT HAUTEMENT RÉSISTANTS À LA CHALEUR, TRANSPARENTS, INCOLORES ET EXEMPTS DE DÉFAUTS, TELS QUE DES TACHES ET DES POINTS, ET PROCÉDÉ DE FABRICATION CORRESPONDANT
Abstract
(EN)
A method for obtaining prepreg - fiber-reinforced composite materials intended for making "Carbon Look" decorative components, characterized by transparency and total absence of color, and free of white spots and/or dots, provides the use of a Lewis acid with latency properties, such as BCl3.(N,N-dimethyl octylamine), as polymerizing catalyst of the epoxy resins used as matrix. The decorative components, after the curing process, in addition to being transparent, colorless and free of defects, such as white spots and/or dots, are also highly heat-resistant, because the cured composite obtained from prepreg manufactured with an appropriately formulated matrix, reaches high glass transition temperature values.
(FR)
L'invention concerne un procédé d'obtention de matériaux composites à base de préimprégné renforcés par des fibres destinés à la fabrication d'éléments décoratifs ayant un "aspect de carbone", caractérisés par une transparence et une absence totale de couleur et exempts de taches et/ou de points blancs. Selon l'invention, un acide de Lewis présentant des propriétés de latence, tel que BCl3.(N,N-diméthyloctylamine) est utilisé en tant que catalyseur de polymérisation des résines époxy utilisées comme matrice. Les éléments décoratifs, après le traitement de durcissement, en plus d'être transparents, incolores et exempts de défauts, tels que des taches et/ou des points blancs, sont également hautement résistants à la chaleur, étant donné que le composite durci obtenu à partir d'un préimprégné fabriqué avec une matrice formulée de manière appropriée atteint des valeurs de température de transition vitreuse élevées.
