We determined the physical and mechanical properties of a cyloaliphatic epoxy resin that was cured using a liquid anhydride plus 1-methylimidazole as a catalyst. The resin system has a low viscosity and a long gel time, making it suitable for wet filament winding. The system cures at low temperatures (100–120°C) to yield strong, high modulus resins. High glass transition temperatures (>200°C) can be achieved with curing at 150°C. The cost of the resin system is low compared to other elevated-temperature resins. Data on aging at 150°C in air are presented. Erratum to this paper appears in 3(2).
