Tests characterizing an epoxy system that contains 5% rubber and is suitable for wet-filament winding are described. The resin is a bisphenol-A rubberized epoxy diluted with an aliphatic diglycidyl ether and cured with an aromatic amine. The viscosity and pot life were measured and the progress of cure was monitored so an optimum cure could be chosen. Mechanical tests were performed on the cured resin. The low viscosity (0.95 Ps.s) and long pot life (29.3 h) make for ease of processing. A cure cycle of 1.5 h at 90/sup 0/C plus 2 h at 130/sup 0/C gives a cured resin having a glass transition temperature of 104/sup 0/C. The heat-cured material has a tensile strength of 76.1 MPa and a modulus of 2.43 GPa. Kevlar 49 composites of 60-, 65-, and 70-vol % fiber were prepared and tested. Results are presented and compared to two other Kevlar 49/epoxy composites.
