摘要：

The ZrC-SiC ceramics were introduced inside carbon fabric uniformly in one-step by vibration assisted injection. This novel method achieved a relative density of green body at 45%, nearly 50% higher than that of without vibration. The composite obtained a rivaling flexural strength at 185 +/- 12 MPa, graceful fracture mode with fracture toughness at 5.86 +/- 0.16 MPa.m(1/)2 and work of fracture reaching 1284 J/m(2), 2 times of the value without vibration. By comparison, a poor fracture toughness and mediocre flexural strength of 4.05 +/- 0.27 MPa.m(1/2) and 113 +/- 19 MPa are equipped with the non-vibration treated one.
