    Abstract: The present invention provides curable moldable compositions comprising from 10 to 80 volume % of heat resistant fiber compositions, a two component resin mixture of (i) one or more epoxy resins, and (ii) a hardener comprising a combination of triethylenetetraamine (TETA) and from 3 to 15 wt.%, based on the weight of the TETA, of 2-phenylimidazole (2-PI). The compositions cure to provide composite articles having a short demold time of 90 s or less at 130 °C and 101 kPa and a high DSC glass transition temperature (Tg) of from 130 to 180 °C when cured at 130 °C for 90 seconds at a pressure of 101 kPa. The invention enables lightweight, heat resistant composite articles, such as for use in automotive applications.

    Abstract: A two-component curable epoxy resin system including a dye solution. 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 triethylene diamine in specific amounts as a catalyst. The system has beneficial curing characteristics with desired color that make it useful for producing fiber-reinforced composites in a resin transfer molding process.
