“…Additionally, the preparation process is complex and the ceramic structure and ceramic property are greatly affected by complicated factors. Generally, the organic polymer pyrolyzing route is applicable to the preparation of ceramic fiber [50], ceramic coating [51], porous ceramic [18], or fiber reinforced ceramic matrix composite [19]. However, by this method, it is difficult to prepare a dense bulk ceramic particularly with large dimensions [12].…”

Abstract:In the past twenty years, Si-B-C-N ceramic has attracted wide attention due to its special structure and outstanding properties. The ceramic generally has an amorphous or a nano-crystalline structure, and has excellent structural stability, oxidation resistance, creep resistance and high-temperature mechanical properties, etc. Thus, Si-B-C-N ceramic attracts many researchers and finds potential applications in transportation, aerocraft, energy, information, microelectronics and environment, etc. Much work has been carried out on its raw materials, preparation processes, structural evolution, phase equilibrium and high-temperature properties. In recent years, many researchers focus on its new preparation methods, the preparation of dense ceramic sample with large dimensions, ceramic matrix composites reinforced by carbon fiber or SiC whisker, or components with various applications. Research on Si-B-C-N ceramic will develop our insight into the relationship between structures and properties of ceramics, and will be helpful to the development of novel high-performance ceramics. This paper reviews the preparation processes, general microstructures, mechanical, chemical, electrical and optical properties, and potential applications of Si-B-C-N ceramic, as well as its matrix composites.

“…Generally speaking, coatings (Ref [5][6][7][8][9][10][11][12][13][14] on CFs include metal coatings, ceramic coatings, and composite coatings. Among these three coatings, the binding force between metal coatings and CFs is the strongest and the coatings are not easy to crack and abscise.…”

Electroplating technique was applied to coat carbon fibers with nickel. Before plating, the initial fibers were pretreated to improve the wettability in bath. The electroplating parameters were optimized to obtain highquality nickel-coated carbon fibers, and the effects on plating were studied. The coated carbon fibers were characterized by SEM, XRD, and XPS. The coatings are uniform, smooth, bright, and adherent to carbon fibers not only along length but also along the diameter of the filaments, and mainly composed of pure nickel. Metal-carbon-oxygen bonds are present at the interface between nickel coatings and fibers, which provides the interfacial binding force. The results of performance tests showed that the nickel-coated fibers possess a good bonding strength not less than 78.5 kPa, and exhibit excellent oxidation resistance at high temperature. Compared with the initial fibers, the wettability with aluminum is also improved obviously.

“…The liquid precursor method involves coating the C-C composite with precursors prior to composite lamination and densification. Although, there has been significant work on developing UHTC coatings for oxidation protection of carbon fibers and C-C composites [9][10][11][12][13][14][15][16] there has been limited work on developing ZrB 2 and B 4 C inhibited C-C composites. The goal of this research is to investigate alternative C-C composite inhibition processing methods using precursors to ZrB 2 and investigate high-temperature oxidation and ablation testing methods using oxyacetylene torch testing on commercially available B 4 C filled C-C composites.…”
