Abstract

The effect of a simulated flywheel service environment on the longitudinal tensile properties, both static and in fatigue, of a filament-wound Kelvar 49/epoxy composite was presented in a recent paper. The epoxy, formulated at the Lawrence Livermore National Laboratory, was DER 332/Kelpoxy G293/Helox 68/Tonox 60–40 (77/23/65/37.3), and the composite was cured first at 60°C for 4.5 h and then at 130° C for 3 h. The effect of the same environment (vacuum and temperature) on the remaining properties, that is, longitudinal compression, transverse tension, transverse compression, and longitudinal shear, are described here.
