Silicon Carbide Fiber

Silicon carbide fiber is an ideal material for applications requiring high temperature resistance, with twice the strength and 20% greater heat resistance compared to traditional nickel-based superalloys while remaining lighter while maintaining strength even at extreme temperatures.

Woven SiC fibers find wide use across aerospace and aviation industries as well as in metallurgy applications; this segment is expected to hold the greatest market share.

High-temperature resistance

Silicon carbide fiber is an extremely strong and oxidation-resistant material with outstanding chemical resistance, widely used in aerospace component production as well as protecting other components from damage. Furthermore, its high temperature resistance, strength, corrosion resistance and abrasion resistance make it suitable for use in extreme environments.

Silicon Carbide Fiber Market can be divided into two broad categories, continuous and woven forms, with applications including Aerospace, Energy & Power and Ceramic Matrix Composite being among its end uses. Continuous SiC fiber is projected to lead the global market due to its superior high temperature resistance as well as fatigue and corrosion resistance properties; projected compound annual growth for this segment between 2024-2030 is 35.9% compound annually.

Silicon carbide fiber offers excellent resistance to oxidation at high temperatures due to being composed of near-stoichiometric silicon and carbon particles with very little oxygen present, making it an excellent choice for use in jet aircraft or other high-speed vehicles operating under harsh environments such as jet aircraft. Furthermore, its excellent oxidation resistance ensures its structure remains intact even under high temperatures.

Corrosion resistance

Silicon carbide fiber possesses outstanding corrosion resistance, making it suitable for chemical industry components and tank construction projects. Furthermore, its high modulus makes it strong enough to withstand heavy loads and stresses without failure or strain. Furthermore, silicon carbide can resist oxidation and oxidative cracking processes, making it suitable for high temperature environments.

This material is often utilized in aerospace and military equipment applications for reinforcing ceramic or metal matrix composites, due to its excellent high-temperature oxidation resistance, strength, low density characteristics. Furthermore, its excellent thermal conductivity allows it to quickly dissipate heat at very high temperatures.

Silicon carbide’s ability to withstand high-temperature environments has made it an indispensable material in the energy sector. It serves as an insulator in nuclear reactors and as part of land-based turbine refractories; additionally it is often used as a lining material in steam generators, power plant turbines and industrial furnaces – offering both heat resistance and chemical stability while decreasing maintenance costs.

Silicon carbide fibers come in both whisker and continuous forms. While whisker fibers are used in composites, continuous fibers offer higher strength and modulus than their whisker counterparts. Production methods for continuous fibers range from the Yajima process using pre-ceramic liquid polymers to producing solidified green (unfired) fibers to various other methods; both types possess excellent specific strength, stiffness, thermal expansion coefficient, electrical conductivity properties that open up numerous applications across aerospace, military weapons/equipment/equipment/sports equipment/automotive industries among many other potential industries.


Silicon Carbide (SiC) fiber is a lightweight material commonly found in aerospace industry applications as well as automobiles and other machinery. Crafted from silica and carbon, this fiber boasts high thermal conductivity with low density; good refractoriness; strong corrosion resistance; good refractory characteristics, strong corrosion resistance properties as well as being very temperature resistant, making SiC an excellent alternative to metal in jet engines or ceramic matrix composites as an alternative solution.

Continuous SiC fiber market held 33.3 percent of the global market in 2023 and is projected to experience compound annual compound annual growth rate of 33.5 percent between 2024-2030. The rise of continuous SiC fibers can be attributed to their increasing use for lightweight applications in aerospace, energy and power, nuclear power generation sectors and high radiation environments, drawing increasing interest.

Silicon carbide fiber stands out from carbon fiber by being able to retain its performance under high temperature conditions, leading to new applications for this material. Silicon carbide fiber has many uses besides ceramic brake discs and bulletproof vests – for instance it can act as seal rings on pump shafts that run at high speed as well as dissipating frictional heat quickly when operating at high speed and under stress for prolonged periods.

High modulus

Silicon carbide fibers offer high modulus, making them suitable for composite applications. Their thermal stability makes them corrosion- and chemical attack-resistant at higher temperatures; furthermore, their chemical and physical resistance also allows them to be used in various applications like wafer tray supports and paddles in semiconductor furnaces as well as resistance heating elements, thermistors, varistors or resistance heaters.

Silicon carbide fiber production involves various manufacturing approaches. One of the oldest, known as the Yajima process, uses pre-ceramic liquid polymer injected through a spinneret to produce solidified green (unfired) fibers which are then fired at high temperature furnaces. More modern manufacturing approaches such as Lely’s employ molten mixtures of silicon and carbon to form SiC sinter, then drawn into long thin fibers by drawing.

Silicon carbide fibers have an extremely high modulus and can be utilized in metal, ceramic and polymer matrix composites (CMC, MMC and CMC). Their lightweight construction and superior strength and stiffness properties at very high temperatures makes them suitable for CMC, MMC and CMC composites. In addition, these fibers help improve ceramic, metal and polymer composites by decreasing thermal conductivity while increasing high temperature resistance while contributing to overall structural integrity as well as fatigue life extending fatigue life of components; vibration damping capabilities as vibration damping or thermal insulation being great options as well.
