In this report we present data sheets summarizing engineering design results we obtained for filament-wound composite materials that are suitable for flywheel applications. The composites include 60 vol% Kevlar 49 in two different epoxy matrices;60, 65, and 70 vol% E glass in a room-temperature curable epoxy matrix;and 50, 55, 60, 65, and 70 vol% S-2 glass in the same room-temperature curable epoxy matrix. We present information on mechanical and thermal properties for the composites, including elastic constants, compliance components and invariants, and ultimates. We also include average stress-strain curves for tension, compression, and shear. The values given are for good quality filament-wound composites prepared by commercially feasible techniques.
