Fiber - Wikipedia

Fiber or fibre (from Latin: fibra) is a natural or man-made substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.. Synthetic fibers can often be produced very cheaply and in large amounts compared to

Ceramic fibers, such as silicon carbide fibers, are used as reinforcement for ceramic- and metal-matrix composites. The fibers enhance toughness, strength, stiffness, and creep resistance in the composites. Silicon carbide fiber is desirable as a reinforcing fiber because it is predicted to have high elastic modulus and high tensile strength.

Polymorphs of silicon carbide — Wikipedia …

Silicon carbide (SiC) is unique in this regard as more than 250 polymorphs of silicon carbide had been identified by 2006, with some of them having a lattice constant as long as 301.5 nm, about one thousand times the usual SiC lattice spacings. The polymorphs of SiC include various amorphous phases observed in thin films and fibers, as well
