Vehicle leaf spring with a longitudinal discontinuity for crack propagation

摘要

A vehicle suspension member such as a leaf spring (50) is provided comprising at least one composite leaf or plate (2) having a second layer (12) sandwiched within a first layer (10) in such a manner as to provide at least one discontinuity therein effective to divert crack propagation in a direction generally parallel to a longitudinal axis ("L/A") extending between opposite ends of plate (2).
