A Cycloaliphatic Epoxy Resin/Anhydride System Usable Up to 150 deg C,

Abstract

We determined the physical and mechanical properties of a cycloaliphatic 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 deg C) to yield strong, high modulus resins. High glass transition temperatures (>200 deg C) can be achieved with curing at 150 deg C. The cost of the resin system is low compared to other elevated-temperature resins. Data on aging at 150 deg C in air are presented. jg p.3
