“…The main reason for this is their low cost, ease in fabrication, and flexibility in casting to near-net shape [14][15][16][17][18]. Furthermore, in order to make the use of SFRCs for such applications commercially viable, efforts have been made (and continue) to reduce their processing time and cost using novel methods and techniques [4,19,20]. The fabrication of almost all SFRCs is done using the hot-pressing route.…”

The prime objective of this research was to study the influence of hot-pressing pressure and matrix-to-reinforcement ratio on the densification of short-carbon-fiber-reinforced, randomly oriented carbon/carbon-composite. Secondary objectives included determination of the physical and mechanical properties of the resulting composite. The 'hybrid carbon-fiberreinforced mesophase-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 pressure with phenolic resin. The effect of the impregnation cycles was determined using measurements of microstructure and density. The results showed that effective densification strongly depended on the hot-pressing pressure and reinforcement wt%. Furthermore, results showed that compacts processed at lower hot-pressing pressure, and at higher reinforcement wt%, gained density gradually during three densification cycles and showed the symptoms of further gains with additional densification cycles. In contrast, samples that were hot-pressed at moderate pressure and at moderate reinforcement wt%, achieved maximum density within three densification cycles. Furthermore, examination of microstructure revealed the formation of cracks in samples processed at lower pressure and with low reinforcement wt%.

Flexural fatigue behavior of a cross-ply laminated carbon/carbon composite had been studied. The results showed that fatigue behavior and residual strengths of the composite had a close relationship with the maximum applied stress level applied in the fatigue test. In the case of the stress level higher than the fatigue limit, specimens were serious delaminated after fatigue. In the fatigue limit stress level, different kinds of interfaces inside the composite were weakened after fatigue, and the residual flexural and interlaminar shear strength slightly increased and decreased, respectively. When the stress level was lower than the fatigue limit, only interfaces between carbon fibers inside one bundle were evidently weakened, and both of the residual flexural and residual interlaminar shear strengths were significantly improved.

“…Nevertheless, the oxidation of carbon-carbon composites above 370 8C limits their application in oxygen containing environment. As a result, the development of reliable oxidation protection is crucial to utilizing the full potential of carbon-carbon composites [1,2]. Strife and Sheehan [3] have stated that, silicon-based ceramics coatings, like SiC and Si 3 N 4 , could meet the requirement below 1800 8C.…”
