Overview:

Non-metallic composite materials have made continue to make gains in major aircraft applications such as fuselage and wings. Although non-metallics will support a larger percentage of aircraft components, metallic materials are not going away and will continue to be a crucial part of any aircraft system. As such, efforts continue to show gains in performance and cost. To do so, advanced materials must be incorporated into new designs and low cost manufacturing approaches. This program reports on recent materials, design and manufacturing technology efforts aimed at reducing the weight and final cost of aerospace structures. Successful implementation of these technologies in new components will be reviewed and case studies discussing cost/benefit analyses are presented. Benefits offered by different product forms such as extrusions, forgings and castings, and improved joining technologies are reviewed. Champion: R. J. Rioja, Alcoa Technical Center
