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

05.02.2012· The following responses were evaluated: apparent density, water absorption, flexural strength, modulus of elasticity. The results were compared to those manufactured with no silicon carbide particles. It was observed that the silicon carbide particles provided the increase of the apparent density and flexural strength of the composites.
TOKYO -- Silicon carbide (SiC) fibers are emerging as an alternative to traditional, nickel-based superalloys for components requiring high heat resistance, such as aircraft engine parts.
Silicon carbide ceramic (SiC) is an advanced ceramic material containing silicon and carbon. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics.

filament silicon carbide-type fibers. HI-NICALON™ is manufactured near-oxygen-free using electron-beam curing. The fiber is homogeneously composed of ultra-fine beta-SiC crystallites and carbon. The fiber has excellent strength and modulus properties, and has higher thermal stability than NICALON™. HI-NICALON™ is highly resistant 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.
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

The use of a high modulus ceramic fiber, such as boron carbide, in brake pads can significantly prolong the life of brake pads. Boron carbide fiber can be used in any type of break pad by uniformly distributing short or long fibers in the pad matrix and thereby reinforcing.
Silicon carbide maintains its strength even at temperatures up to 1400°C. Notable features of this material are extremely high thermal conductivity and electrical semiconductivity. Silicon nitride has high hardness and corrosion reisistance due to its chemical and physical stability.
Sandwich panel structures with stiff, strong face sheets and lightweight cellular cores are widely used for weight sensitive, bending dominated loading appliions. The flexural stiffness and strength of a sandwich panel is determined by the stiffness, strength, thickness, and separation of the face sheets, and by the compressive and shear stiffness and strength of the cellular core.
