Silicon Carbide Fibre is a continuous multi-filament tow consisting of fine filaments of SiC crystals. The fibre possesses high strength, heat and corrosion resistance, even in a high temperatures. It is oxidation resistant, with a high wettability and is consequently used in composites with metals, plastics and ceramics. Silicon Carbide Fibre brings improved performance opportunities to matrices of these materials, and acts as composite reinforcement. A common trademark and brand name for Silicon Carbide Fibre is NicalonTM–an advanced material mainly used in the aerospace industry. It is slated that next-generation aircraft engines will apply NicalonTM based composite materials to reduce weight, increase durability and fuel efficiency. Silicon carbide reinforced titanium (TMC), aluminum (MMC) and ceramic composites (CMC) are high in strength and stiffness, lightweight, and maintain their properties at high temperatures, making them suitable for a number of industries and applications.
