ABSTRACT:
A constant cross-sectional area filament wound composite material leaf spring of optimal energy storage efficiency given the constraints of filament winding and maximum spring width comprises a portion which widens toward the end of the spring, the rate of increase of width of the spring being such that the longitudinal side surfaces of the spring along such portions follow a lateral, outwardly convex curve of radius R.sub.I, wherein R.sub.I at each point is substantially equal to the camber, i.e., the longitudinal radius of curvature R.sub.C at that point.
