DEVELOPMENT OF A METHOD FOR FABRICATING METALLIC MATRIX COMPOSITE SHAPES BY A CONTINUOUS MECHANICAL PROCESS

摘要

2" (.508m) Al/B tube fabrication attempts continued. Despite relatively-superior temperature control, the consolidation characteristics did not improve as expected, inadequate binder removal was positively identified as the cause largely responsible because the graphite residue generated during heating acted as a diffusion barrier. A new method to align the filaments without mat making was employed. Flat strips or modules were prepared by drawing aluminum clad boron ends encased in an aluminum jacket. The gradual reduction in area and consequent gentle squeezing aligned the binder free matrix-clad-filament (MCF) ends well. The MCF count and die sequence are described here in detail.
