Abstract
The thermo-mechanical properties of SiC particulate-reinforced SiC composites (SiC-PRCs), fabricated using precursor impregnation & pyrolysis (PIP) process, were analyzed up to 2000 ℃. The relative density of the SiC-PRCs after 4 PIP cycles was 88.6 %. The number of PIP cycles required decreased to nearly half compared with the conventional PIP method by using ultra-high concentration slurries up to 70 vol%. In addition, room-temperature bending strength (215 MPa) and Young's modulus (269 GPa) improved as the solid loading of the slurry increased. The bending strength increased to 232 MPa at 2000 ℃ in Ar. Despite the thermal deterioration of the precursor-derived ceramics (PDC), the mechanical properties of the PRC did not deteriorate up to 2000 ℃ because the PDC fixed the position of thermally stable SiC filler particles, which were densely packed and mostly endured the stress. Moreover, partial densification at high temperature further improved the thermo-mechanical properties of the PRC.
