Abstract

A hinge apparatus is capable of reliably withstanding a great number of stressor cycles. A layer of an inflectable fiber-reinforced composite material is embedded between two layers of a fiber reinforced composite material of high stiffness. The latter are formed with a separating joint along the line of inflection.
