Fabrication of Fiber‐Reinforced Ceramic Composites by the Modified Slurry Infiltration Technique

Abstract

A new technique for the homogeneous infiltration of concentrated and viscous ceramic filler slurries into stacked 2D‐woven fabrics has been developed by introducing a flexible mold. The inner space of the mold expanded during slurry infiltration, which enhanced penetration of the viscous slurry into the woven fabric layers. The subsequent precursor impregnation and pyrolysis process yielded fiber‐reinforced ceramic composites with scarce macropores between the fabric layers.

Effects of SiO2 formed on SiC filler particulates on the thermal and mechanical properties of a SiC/Si-C-N composite

“…5) There have been also publications, however, showing contradicting results. 6) The reason for the inconsistency is not yet clear.…”

Fabrication and physicochemical properties of particulate-reinforced precursor-derived Si-C-N ceramics

“…6) However, their CTE values are higher than that of Si-C-N (6.9, 8, 7.2 and 9.4 × 10 -6 /°C, respectively). 5) In addition, their density (5.99, 4.42, 5.03 and 5.32 g/cm 3 , respectively) and cost are not as low as those of SiC and Si3N4. 5) Here we report processing, mechanical and thermal properties of particulate-reinforced ceramic composites (PRC) composed of oxide or non-oxide filler materials (Al2O3, Y2O3, SiC and Si3N4) and precursor-derived Si-C-N ceramic matrix.…”

“…3) Ceramic fillers such as SiC have been used for the fabrication of fiber-reinforced ceramic composites (FRCC), and substantial improvement has been achieved with respect to the processing time and performances. The present authors significantly reduced the total processing time of Cfiber/SiCfiller/Si-B-C-Nmatrix composites by using the SiC filler.…”

“…12) Netzsch STA 501 was used in order to measure the high temperature mass stability of the PRC up to 2100°C (Ar, heating rate: 3°C/min). Creep test was performed using bar-type specimens (2 × 2 × 8 mm 3 ) under a compressive stress of 100 MPa at 1350°C…”

Effects of the Sintering Temperature on the Structure and Properties of the Alumina Foamed Ceramics

“…The fibers with high modulus and high strength have been used to reinforce the ceramic matrix to prepare composites, called fiber reinforced ceramics matrix composites (FRCMC), which attracted much more attention due to its excellent properties, such as high temperature oxidation resistance, high strength, high elastic modulus, good rigidity, and good chemical stability. The study and application on dense FRCMC have achieved great success [9][10][11][12][13][14] .…”
