ABSTRACT:
Lightweight, cost-effective composite seat back frames comprise braided carbon fiber reinforced attachment portions connected by braided, glass fiber-reinforced, generally U-shaped back portions, all these portions impregnated with a polymeric matrix resin. One or more of the braided glass or carbon fiber portions are preferably woven by a multiaxial weaving machine to maximize composite properties. The braids may be woven around a permanent or removable mandrel, and may contain pivot bushings or seat articulation hardware. The seat back frames thus produced are lighter than their aluminum counterparts.
