The authors proposed a new fabrication process of 3-D C/C composites, in which unidirectionally reinforced C/C rods are fabricated first, by CVI (Chemical Vapor Infiltration) process. Three dimensional preforms are then composed of the rods. C/C composites are fabricated by impregnating them with resin and pitch powder and carbonizing.
Fundamental CVI conditions of C/C rods such as infiltration temperature, gas pressure and proportion of gas mixture were discussed first. Mechanical properties of tri-axially reinforced 3-D C/C composites were examined, and good tesnsile and compressive performance were verified. Thermal expansion of this material was also examined and excellent thermal stability in wide temperature range was shown.
