curable epoxy resin system, process for forming a fiber reinforced epoxy composite and cured fiber reinforced composite

摘要

abstract "curable epoxy resin system, process for forming a fiber reinforced epoxy composite and cured fiber reinforced composite" is described a bicomponent curable epoxy resin system. 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 substituted phenolic compounds, carboxylic anhydride or carboxylic acid ester, iii) an amino acid as catalyst. The system has beneficial curing characteristics that make it useful for producing fiber reinforced composites in a resin transfer molding process.
