Filament Winding Epoxy Resins for Elevated Temperature Service,

Abstract

We formulated and evaluated six epoxy resin systems suitable for wet filament winding of high-performance flywheels. We judged the resins on five criteria: (1) low viscosity (1.0 Pa.s at 25 deg C), (2) long gel time (> 20 h for a 30-g mass at 25 deg C), (3) high glass transition temperature (> l80 deg C), (4) high tensile strength with high modulus, and (5) good retention of mechanical properties upon accelerated heat aging (7 d at l75 deg C). From the results of mechanical and physical tests, we conclude that our resin 1 (Ciba 0510/RD- 2/APCO 2330) is the best resin for the intended application. Our resin 2 (Ciba 0510/Tonox 60-40) is the second choice; it offers a lower tensile strength and a larger loss in strength upon heat aging than resin 1 but has the highest glass transition temperature.
