BUSHING CONSTRUCTION FOR A FIBER REINFORCED PLASTIC LEAF SPRING Abstract of the Disclosure A fiber reinforced plastic leaf spring including a curved central section and a pair of end sections, each having a bushing to receive a connecting member. The spring is formed from a plurality of long- itudinally extending substantially continuous strands of fibrous material impregnated with a cured thermo- setting resin which are wound in a loop configuration around the bushings. The windings consist of a pair of generally parallel runs which extend between the bush- ings and are disposed in contiguous relation and the resin is cured to formed an integral structure. Each bushing includes a tubular section and at least one circumferentially extending rib that extends outwardly from the tubular section and is encapsulated in the fibrous windings. The ribs act to prevent delamination of the two runs along the neutral axis of the spring when the spring is subjected to load in service.
