The service conditions of the hot-end components of aeroengines are extremely harsh. 1 In addition to the complex load and water vapor environment, the materials are suffered damage from sand and dust, which are ingested into the engine by the intake air. 2 Silicon carbide fiber-reinforced silicon carbide matrix composites (SiC f /SiC) are considered to be one of the most promising thermal structural materials in the next generation of aero-engines due to their low density and excellent thermomechanical properties at high temperatures. [3][4][5] Coating an environmental barrier coating (EBC) on their surface can further improve the high temperature oxidation resistance of the SiC f /SiC composite. [6][7][8] Generally, EBC is mainly composed of two parts with different functions. One layer made of rare earth silicates (such as Yb 2 SiO 5 , La 2 SiO 5 ) exposing to the environment acts as a thermal blocker of high heat flow at high temperature and an isolator for water-oxygen and corrosion gas; the other layer composed of Si acts as the bonding layer to relief the mismatch in coefficient of thermal expansion (CTE) between the composites and the outer coatings. [9][10][11][12] The main components of the ingested particles in the engines are calcium-magnesium-alumina-silicon (CMAS).

Silicon carbide (SiC) ceramic and related materials are widely used in various military and engineering fields. The emergence of additive manufacturing (AM) technologies provides a new approach for the fabrication of SiC ceramic products. This article systematically reviews the additive manufacturing technologies of SiC ceramic developed in recent years, including Indirect Additive Manufacturing (Indirect AM) and Direct Additive Manufacturing (Direct AM) technologies. This review also summarizes the key scientific and technological challenges for the additive manufacturing of SiC ceramic, and also forecasts its possible future opportunities. This paper aims to provide a helpful guidance for the additive manufacturing of SiC ceramic and other structural ceramics.

“…Owing to their excellent heat resistance, oxidation resistance, chemical stability, wave-absorbing, and heat conductivity, SiC fibers are widely used as reinforcements in ceramic matrix composites (CMCs) in the aerospace and nuclear energy industries. 1,2 The preparation of SiC fibers from polymer precursors was first reported by Professor Yajima and his partners in 1978. 3 The first commercial continuous SiC fibers, known as Nicalon, were produced by Nippon Carbon Company in 1982.…”

“…Over the past 40 years, three generations of SiC fibers with different elemental compositions and microstructures have become available. 2,4 Their mechanical properties, such as tensile strength and elastic modulus, have been well-studied under various experimental environments. [5][6][7][8][9][10][11][12] However, the SiC fiber compressive strength, which is a considerable and instructive index for ceramic matrix composite design, 13 is difficult to measure owing to its high length-todiameter ratio.…”

SiC fibers have been widely investigated as reinforcements for advanced ceramic matrix composites owing to their excellent high-temperature properties. However, the axial compressive strength of SiC fibers has not been thoroughly studied. In this study, the compressive behavior of two SiC fiber types containing different compositions and thermal degradation were characterized by tensile recoil measurements.Results illustrated that the SiC fiber compressive strength was 30%-50% of its tensile strength, after heat treatment at 1200℃-1800℃ for 0.5 h in argon. The fiber compressive failure mechanism was studied, and a "shear-bending-cleavage" model was proposed for the recoil compression fracture of pristine SiC fibers. The average compressive and tensile strengths of the pristine SiC-II fiber were 1.37 and 3.08 GPa, respectively. After treatment at 1800℃ for 0.5 h in argon, the SiC-II fiber compressive strength decreased to 0.42 GPa, whereas the tensile strength reduced to 1.47 GPa.The mechanical properties of the fibers degraded after high-temperature treatment.This could be attributed to SiC grain coarsening and SiC x O y phase decomposition.
