摘要：

Traditional densification of UHTC matrix composites normally requires towering sintering temperature over 1800 degrees C and high pressure, or dozens of PIP circles around 1600 degrees C. Illuminated by realization of ferroconcrete, C-f/UHTC-SiC is prepared via a novel densification method and mechanism at 1300 degrees C without pressure, using liquid polycarbosilane to 50 nm SiC as sufficient supplementation to filling holes and ensuring a strong bonding between dispersive ZrC particles inside carbon fabric after slurry injection. The obtained C-f/ZrC-SiC not only achieves high density at 4.19 g/cm(3), but also has robust strength and graceful toughness at 286 +/- 25 MPa and 11.12 +/- 1.25 MPa m(1/2), meanwhile gains a level of ascension in work of fracture to 3046 J/m(2).
