Abstract

The purpose of this study is to investigate the mechanical characteristics of C/C (Carbon-Carbon) composites, where the carbon precursor contains micro-sized glass fibers. The carbon fiber bundle was dipped in the phenolic resin in which micro-sized glass fibers were dispersed uniformly and winding in order to fabricate unidirectional CFRP (CarbonFiber-Reinforced-Plastic) preform. The CFRP preform was carbonized at high temperature with inert atmosphere to fabricate the C/C composites as follows. The preform was heated up to 1273 K and then kept for 1 hr. In second phase, the preform was heated again up to 1773 K and then kept for 1 hr. The test results showed that the bending strength of C/C composites carbonized at 1273 K decreased compared with that of CFRP preform. However, the bending strength of modified C/C composites was increased when the carbonized temperature exceeded 1773 K. Unmodified C/C composites showed almost constant bending strength and modulus with respect to the carbonized temperature. These results suggested that the SiC synthesization between glass fibers and carbon matrix was effectively obtained during the carbonizing procedure.
