| Abstract: | Three dimensional continuous Nicalon - SiC reinforced silicon carbide composites were fabricated by chemical vapor infiltration and polymer impregnation pyrolysis. The interphases were multilayered (PyC/SiC)n.The composites exhibited high mechanical properties and tough fracture behavior. The bulk density and flexural strength are 2. 42 g/cm3 and 530 MPa respectively. |
