<p>A flywheel (1) for storing rotational energy at high energy densities possesses a primary failure mode of delamination. The flywheel is constructed from glassy metal alloy strips (3) having a high specific strength comparable to anisotropic fibers used in high energy density flywheels and, in addition, having isotropic or nondirectional strength properties allowing a fuller utilization of the strength of the material and thereby increasing energy storage capacities. The glassy metal alloy strips are formed into circular layers (2), and a plurality of layers are joined concentrically to build up the flywheel. Joining between strips (3) and layers (2) is accomplished with bonding means such that a substantially mechanically monolithic composite structure results, by providing a bonding shear strength at least equal to the specific strength times the density divided by the aspect ratio of the glassy metal alloy strips (3).</p> |
