Popis: The emergence of large (100–140 μm) diameter silicon carbide (SiC) monofilaments with very high elastic stiffness and fracture strength has led to the development of a new generation of metal matrix composites with axial Young’s moduli above 200 GPa, ultimate tensile strengths of around 1.8 GPa and a 600°C creep rupture life at 1 GPa of several thousand hours or more. These exceptional properties are only obtained when the matrix is fully dense, the fibers remain straight/unbroken and only minimal reaction occurs between the matrix and fiber during processing. One promising approach for accomplishing this involves a two-step vapor deposition/hot consolidation process [Deve, 1995].
