Abstract
An elongated spring member is formed of fiber reinforced plastics, particularly resin-impregnated glass fiber strands, and includes end provisions adjacent the two ends for the reception of attachment elements associated with the use of the spring. The spring includes parallel impregnated strands which have been wound about a rack provided with end supports following which the entire wound resinous product is placed within a mold cavity and cured to provide a spring member having integral, molded end provisions encircled by continuous, uncut reinforcing fibers with or without the inclusion of additional reinforcing material, and which is molded without the formation of any significant waste product. The improved spring member includes transversely disposed end provisions which may comprise a passageway or elongated end members encircled by the reinforced strands and the center axis thereof may be along the neutral axis of the spring body or alternatively, above or below the neutral axis.
