AbstractThe C/SiC composites with a 7-8 ram thickness, a 2.3-2.4 g/cm(3) density, and a Si/C ratio 1.08-1.09 matrix have been fabricated by heaterless chemical vapor infiltration (CVI) in a 25-h deposition time. The C/SiC composites exhibited a damage-tolerant fracture behavior, and its average flexural strength, longitudinal/transverse compressive strength and fracture toughness were 163 MPa, 304/276 MPa and 6.5 MPa m(1/2) respectively. The composites presented a thermal expansion of (1.09-1.93) x 10(-6) degrees C-1 and a thermal conductivity (TC) of 8.34-6.56W/m degrees C in the range 200-1000 degrees C. (C) 2007 Elsevier B.V.
