REVIEW OF RECENT DEVELOPMENTS. FIBER-REINFORCED MATERIALS,
Abstract
The stress-strain behavior of composites made by infiltrating bundles of W wire with molten Cu was reported by workers at NASA Lewis Research Center. NASA Lewis Research Center conducted a study to determine the effect of alloying the matrix on the tensile properties and microstructure of W-fiber-reinforced composites. Composites were made of W wires infiltrated with binary alloys of Cu with Al, Cr, Co, Nb, Ni, Ti, and Zr. In addition, selected Ni-base and Cobase alloys were used as matrices. Analysis of composites made by infiltrating alpha-Al2O3 whiskers with molten Ag showed that between 80 and 97% of the whiskers' strength can be utilized at room temperature. At temperatures exceeding 90% of the melting point of Ag, the utilization factor is 30 to 60%. A composite made from Rene' 41 reinforced with fine alpha-Al2O3 was made with no apparent damage to the whiskers as a result of exposure to the liquid alloy during fabrication. (Author)
