Enhancement of the microwave absorption properties of PyC-SiCf/SiC composites by electrophoretic deposition of SiC nanowires on SiC fibers

Synthesis of coatings on SiC fibers and their effects on microstructure and mechanical properties of SiCf/SiBCN composites

“…[7][8][9]40,41 A survey of the published literature shows that process modeling of CMCs has been studied by a number of researchers. Processes that have been modeled include RMI, 15,16 CVD, 17,18 CVI, [19][20][21][22] and Sol-Gel Infiltration. 23 Impregnation of alumina matrix in eight-harness satin Nextel 610 fabric has been studied numerically in Ref.…”

“…[14][15][16][17][18] Pyrolytic carbon (PyC), which has a layered crystal structure, is the common coating for SiC fibers (SiC f ). [19][20][21][22] In this regard, He et al have fabricated the SiC nanowires/ pyrocarbon (SiCnws/PyC) core-shell structure by chemical liquid vapor deposition process. Results showed that the modified C/C-ZrC-SiC composites became denser with the increasing thickness of PyC.…”

Effect of slurry and sol‐gel introduce SiCnws on ablation and bending behaviors of modified SiCf/HfC‐SiC composites

“… 30 reported that the introduction of SiC nws significantly improved both fracture toughness and strength of the modified C f /SiC composites. At present, many methods of introducing SiC nws into composites have been explored, such as the sol‐gel, 31 slurry, 32 and electrophoretic deposition methods 33 . The advantages of the sol‐gel method are low cost and high efficiency.…”

Rationally designed structure of mesoporous carbon hollow microspheres to acquire excellent microwave absorption performance

“…Recently, there have been numerous research studies about microwave absorbers, including magnetic-based nanomaterials (magnetic alloys, magnetic metals, and magnetic oxides), [9][10][11][12][13][14][15] carbon-based nanomaterials (carbon nanotubes, graphene carbon ber, and porous carbon), 6,[16][17][18][19][20][21][22][23][24] and other special nanomaterials. [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] Magnetic-based nanomaterials, such as CoNi particles, have become one of the best choices of microwave absorbers on account of their unique ferromagnetic features. These features contain high magnetocrystalline anisotropy, high saturation magnetization, and high Snoek's limit.…”
