Fiber Composite Flywheel Program: filament-wound composite data sheets

Technical Report ·
OSTI ID:6493963
Data sheets are presented which summarize engineering design results 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. Information is presented on mechanical and thermal properties for the composites, including elastic constants, compliance components and invariants, and ultimates. Average stress-strain curves for tension, compression, and shear are included. The values given are for good quality filament-wound composites prepared by commercially feasible techniques.
