Joining of C_f/SiC Ceramic Matrix Composites: A Review

Abstract

Carbon fiber-reinforced silicon carbide (Cf/SiC) ceramic matrix composites have promising engineering applications in many fields, and they are usually geometrically complex in shape and always need to join with other materials to form a certain engineering part. Up to date, various joining technologies of Cf/SiC composites are reported, including the joining of Cf/SiC-Cf/SiC and Cf/SiC-metal. In this paper, a systematic review of the joining of Cf/SiC composites is conducted, and the aim of this paper is to provide some reference for researchers working on this field.

Effect of metallization temperature on brazing joints of SiC ceramics and 2219 aluminum alloy

“…It is difficult to prepare parts with complex shape because of the inherent brittleness of ceramics. [1][2][3][4][5] 2219 aluminum alloy has the outstanding properties of low density, excellent electrical conductivity, good chemical stability, and remains the principal structural material for aircraft parts that have been in service in recent years. 6 In reality, they usually need to be connected to perform certain functions.…”

“…SiC ceramics possesses the thermal shock resistance and low sensibility to oxidation as a lightweight structure material in aerospace technology. It is difficult to prepare parts with complex shape because of the inherent brittleness of ceramics 1–5 . 2219 aluminum alloy has the outstanding properties of low density, excellent electrical conductivity, good chemical stability, and remains the principal structural material for aircraft parts that have been in service in recent years 6 .…”

Pressureless joining of SiC ceramics with magnesia‐alumina‐silica glass ceramics

“…The intricate shaped SiC hardware is fabricated by joining simple shaped parts. Thus, there is continued research thrust to develop economical joining techniques fulfilling the structural and functional requirements of the target applications 12–45 …”

“…or their combination), 14–16 reaction joining using Ti and Mo foils forming titanium and molybdenum silicides in the bonding layer, 17,18 and reaction bonding via silicon infiltration in the carbon interlayer forming SiC with residual Si in the bonding layer 19,20 . The application of metallic filler joining is limited to low‐temperature structural applications due to its poor high‐temperature strength and oxidation resistance and poor irradiation tolerance 14,21,22 . The nonmetallic filler joining technique includes polymer‐derived ceramic joining, 23,24 transient eutectic‐phase joining using SiC‐based mixed oxide additives, 14,25,26 and glass‐ceramic joining 27–44 .…”
