Abstract
A composite article includes a compressively stressed plating which provides increased static strength and fatigue life. In particular, a fan exit guide vane (1), made of a graphite fiber reinforced composite material and including a conductive plating (7), achieves a 380% increase in static load capability over an unplated composite vane and a low cycle fatigue life of over 1 million cycles through the application of a compressively stressed nickel plating (8) which produces a residual compressive stress state of between -5,000 and -15,000 psi.
