Abstract : An epoxy resin system is described for use in the wet winding of high strength filament wound pressure vessels with aramide fiber. The resin system is composed of a mixture of a plurality of distinct epoxy resins and aromatic curing agents. The epoxy resins were selected to impart particular properties required for the filament winding process and to improve the strength of filament wound pressure vessels. Aromatic amine curing agents were selected to alter the time/temperature gel and cure conditions of the system without significantly altering the final strength of the pressure vessels. The resin system is nominally composed of a mixture of a commercially available epoxy resins comprising diglycidyl ether of bisphenol A, a diglycidyl ester of linoleic dimer acid, and a diglycidyl ether of butanediol and the aromatic amine curing agent comprises a mixture of methylenedianiline and metaphenylenediamine in a 60/40 ratio by weight. The ratios of the components are selected to meet the specific processing needs and the final product requirements.
