Previous studies by the Air Force, NASA and the Vought Corporation have substantiated the fact that many metallic fasteners corrode to some degree when placed on contact with composite structures. Vought initiated an internally funded program to investigate composite fasteners in 1973. Initial manufacturing process development and testing indicated composite fasteners were structurally adequate and would also eliminate galvanic corrosion problems associated with metal fasteners. In August 1977, the Air Force Materials Laboratory awarded a contract to the Vought Corporation, 'Low Cost Innovative Composite Manufacturing - Composite Fastening Systems.' The objective of this program was to establish and demonstrate a unique manufacturing technique applicable to the fabrication of advanced composite airframe structures. The Vought and Air Force funded programs are discussed; material selections, applications and cost analysis are reviewed. (DePo)
