AB - The prime objective of this research was to study the influence of hot-pressing pressureand matrix-to-reinforcement ratio on the densification of short-carbon-fiber-reinforced, randomlyoriented carbon/carbon-composite. Secondary objectives included determination ofthe physical and mechanical properties of the resulting composite. The ‘hybrid carbon-fiberreinforcedmesophase-pitch-derived carbon-matrix’ composite was fabricated by hot pressing.
During hot pressing, pressure was varied from 5 to 20 MPa, and reinforcement wt%from 30 to 70. Densification of all the compacts was carried at low impregnation pressurewith phenolic resin. The effect of the impregnation cycles was determined using measurementsof microstructure and density. The results showed that effective densification stronglydepended on the hot-pressing pressure and reinforcement wt%. Furthermore, results showedthat compacts processed at lower hot-pressing pressure, and at higher reinforcement wt%,gained density gradually during three densification cycles and showed the symptoms of furthergains with additional densification cycles. In contrast, samples that were hot-pressed atmoderate pressure and at moderate reinforcement wt%, achieved maximum density withinthree densification cycles. Furthermore, examination of microstructure revealed the formationof cracks in samples processed at lower pressure and with low reinforcement wt%.
