Processing and Mechanical Properties of C-Fiber Reinforced SiCN-CMCs

Cfiber/SiCfiller/Si–B–C–Nmatrix composites with extremely high thermal stability

“…7a; maximum strength, 208 MPa). The strengths of carbon fiber-reinforced CMC made by PIP are usually low (125 MPa, 150-200 MPa) [36,39]. Ziegler et al reported that the bending strength of a C fiber /Si-C-N matrix CMC was lower than that of a SiC fiber /Si-C-N matrix CMC made using the same processing conditions (125 MPa vs 950 MPa) and attributed this to the formation of cracks which originated from the large difference in the CTE [36].…”
