Abstract : Viable procedures for producing titanium matrix-beryllium wire composites were developed and optimized. The resulting composites were characterized at filament volume fractions ranging from 30% to 50%. The composites feature rule of mixtures strengths and moduli coupled with excellent ductility and impact resistance. Design studies were made for applications employing this material as rotating fan and compressor blading in gas turbines with typical weight savings of 40% being realized. A prototype Be/Ti composite fan blade was fabricated and is awaiting testing. Also, included in this report are mechanical test data and the evaluations thereof for beryllium reinforced aluminum composites. (Author)
