Polymer derived ceramics reinforced with Ti3SiC2 coated SiC fibers: A feasibility study

Influence of Ti3SiC2Fiber Coating on Interface and Matrix Cracking in an SiC Fiber‐Reinforced Polymer‐Derived Ceramic

“…No reaction of Ti 3 SiC 2 with the carbonaceous fiber coating or the polymer/filler-derived ceramic matrix was evidenced, as confirmed by elemental analysis. [15] Linear shrinkage along the fiber direction of 5.5% and volume porosity of the pyrolyzed samples of 6% were measured. Figure 3 presents sliding surfaces of pushed-out filaments and longitudinal sections of corresponding interface domains, as prepared by FIB.…”

“…[10] The layered microstructure favors an unusual deformation capability involving delamination and formation of kink bands within the basal planes, resulting in an outstanding damage tolerance. [15] The conversion of filler-loaded organometallic precursors into ceramics has been noted as one of the most promising techniques of fabrication of dense polymer-derived ceramic composites due to volume reactions during the ceramization of the polymer. Furthermore, the wide variation of MAX phase composition with more than 50 phases reported in the literature [14] can be used to tailor the mechanical and thermal properties of an interface layer in order to optimize fiber/matrix bonding in a composite in this work.…”

“…Ti 3 SiC 2 layers were electrophoretically deposited on continuous SiC fibers prior to incorporation into a polymer-derived ceramic (PDC) matrix. [15] The conversion of filler-loaded organometallic precursors into ceramics has been noted as one of the most promising techniques of fabrication of dense polymer-derived ceramic composites due to volume reactions during the ceramization of the polymer. [16,17] The crucial importance of interfaces has prompted studies of micromechanical [18][19][20][21][22] and microanalytical [23][24][25] characterization of fiber-matrix interactions.…”

Synthesis, pyrolysis of a novel carborane ceramic precursor, and coating on carbon fiber

“…Riedel et al and Motz et al have developed boron and nitrogen (N 2 ) containing ternary and quaternary Si-ceramic phases like silicon-boron-carbon-nitrogen (SiBCN) ceramic with high oxidation resistance, the existence of boron can prevent silicon nitride decomposition and crystallization of ceramic and therefore further stabilize the amorphous state in ceramic. 25 –29 The SiBCN ceramics have better thermal stability, resistance to crystallization, and greater oxidation resistance than silicon-carbon-nitrogen (SiCN) ceramics. 6 However, it is difficult to prepare SiBCN ceramic due to the low diffusion coefficients of Si or B and the thermal stability of its relative nitrogenous compounds in traditional preparation route.…”

Formation of Ti3SiC2 interphase coating on SiCf/SiC composite by electrophoretic deposition

“…When Ti 3 SiC 2 is coated on SiC fiber through EPD, due to the anisotropy of the Ti 3 SiC 2 particles, the coating layer may be formed so that the basal plane of Ti 3 SiC 2 is aligned in a direction parallel to the SiC fiber. Filbert‐Demut et al coated Ti 3 SiC 2 powder onto a large diameter SiC fiber through EPD and Mishra et al maintained the crystal orientation of Ti 3 SiC 2 particles in a constant state using a magnetic field on a flat substrate …”
