Title (EN) EPOXY RESIN COMPOSITION, PREPREG, AND FIBER REINFORCED PLASTIC MATERIAL
(FR) COMPOSITION DE RÉSINE ÉPOXY, PRÉIMPRÉGNÉ, ET MATÉRIAU EN PLASTIQUE RENFORCÉ PAR DES FIBRES
Abstract:
(EN) The embodiments herein relate to an epoxy resin composition comprising a specific type of amine-based epoxy resin containing four epoxy groups per molecule, a prepreg, and a fiber-reinforced composite material. More specifically, the embodiments herein relate to an epoxy resin composition containing a combination of particular types of epoxy resin and curatives that provides high flexural modulus that is suitable for preparing a fiber-reinforced composite material capable of withstanding extreme use environments such as low-temperature environments and high-temperature moisture- absorbing environments. In addition, the embodiments herein relate to epoxy resin systems capable of achieving a high degree of cure (e.g., 85% or more) within a relatively short period of time (e.g., less than two hours) at a relatively low temperature (e.g., 132°C).
(FR) Les modes de réalisation de la présente invention concernent une composition de résine époxy comprenant un type spécifique de résine époxy à base d'amine contenant quatre groupes époxy par molécule, un préimprégné et un matériau composite renforcé par des fibres. Les modes de réalisation de l'invention concernent plus spécifiquement une composition de résine époxy contenant une association de types spécifiques de résines époxy et d'agents de durcissement qui assurent un module d'élasticité en flexion élevé étant appropriée pour préparer un matériau composite renforcé par des fibres capable de supporter des environnements d'utilisation extrême, tels que des environnements à basse température et des environnements absorbant l'humidité à température élevée. Les modes de réalisation de l'invention concernent par ailleurs des systèmes de résine époxy capables d'atteindre un degré élevé de durcissement (par exemple 85 % ou plus) en un laps de temps relativement court (par exemple deux heures) à une température relativement basse (par exemple 132°C).
