2-성분 경화성 에폭시 수지 시스템이 개시된다. 상기 수지 시스템은 폴리 페놀의 폴리글리시딜에터를 80 중량% 이상 함유하는 에폭시 수지 성분을 포함한다. 또한, 이 시스템은 주로 폴리에틸렌 테트라아민을 함유하는 경화제 혼합물을 포함한다. 상기 시스템은 i) 알칼리 금속 염, ii) 카복실산-, 카복실산 무수물- 또는 카복실산 에스터-치환된 페놀 화합물, 및 iii) 아미노산 중 하나 이상을 촉매로서 포함한다. 상기 시스템은, 수지 이송 성형 공정으로 섬유-강화 복합체를 제조하는 데 유용한 유익한 경화 특성을 갖는다. A two-component curable epoxy resin system is disclosed. The resin system includes an epoxy resin component containing at least 80% by weight of a polyglycidyl ether of a polyphenol. The system also includes a hardener mixture containing mainly polyethylene tetraamines. The system includes one or more of i) alkali metal salts, ii) carboxylic acid-, carboxylic anhydride- or carboxylic acid ester-substituted phenol compounds, iii) an amino as a catalyst. The system has beneficial curing characteristics that make it useful for producing fiber-reinforced composites in a resin transfer molding process.
