Beryllium Wire - Metal Matrix Composites Program.
Abstract
In an effort to lower the costs of beryllium reinforced titanium matrix composites two promising approaches have been studied. The first of these is the use of larger diameter (and consequently cheaper) Be wires in place of the conventional 5 mil size. Sizes of 20 and 58 mils have been investigated with successful bonding and theoretical strengths and elastic constants being realized. The second approach employs the coextrusion of Be and Ti to form a low cost composite. Progress has been made in improving the quality of the product of this technique; however, additional work is required to fully realize the potential of this approach. Two components were selected for design study in the reporting period. The first of these, a small fan blade, showed a projected weight savings of 36% in comparing its airfoil weight to the weight of a similar all Ti airfoil. The second component studied was a large fan blade. In this case a totally satisfactory design has not been reached to date. However, a preliminary design which is probably very close to the final design showed a weight savings of 47%. (Author)
