- Fiber or fibre (from the Latin fibra[1]) is a natural or synthetic substance that is significantly longer than it is wide.[2] 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.

Fiber Fiber or fibre (from the Latin fibra) is a natural or synthetic string used as a component of composite materials, or, when matted into sheets, used to make products such as paper, papyrus, or felt. Fibers are often used in the manufacture of other materials.atural fibers include those produced by plants, animals, and geological processes and can be classified according to their origin: 1  Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, ramie, sisal, bagasse, and banana.

POSIX (Portable Operating System Interface) Informally, each standard in the POSIX set is defined by a decimal following the POSIX. Thus, POSIX.1 is the standard for an application program interface in the C language. POSIX.2 is the standard shell and utility interface (that is to say, the user's command interface with the operating system). These are the main two interfaces, but additional interfaces, such as POSIX.4 for thread management, have been developed or are being developed.

- Muscle Structure, Fiber and Cells. Muscular System: Muscle fibers are the cells or basic building block of the muscle. There are a few different types of muscle fiber, each designed for a specific type of muscle activity. Some muscle fibers are good for endurance exercises, other work best for the short bursts of strength exercises. Read on to learn more about muscle structure, and its role in muscle activity.

Elastic fiber Elastic fibers (or yellow fibers) are bundles of proteins found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle cells in arteries. These fibers can stretch up to 1.5 times their length, and snap back to their original length when relaxed.

Synthetic fiber Synthetic fiber. Synthetic fibers (British English: synthetic fibres) is the result of extensive research by scientists to improve on naturally occurring animal and plant fibres. In general, synthetic fibers are created by extruding fiber forming materials through spinnerets into air and water, forming a thread. Before synthetic fibres were developed, artificially manufactured fibres were made from polymers obtained from petrochemicals.

Elastic fiber [edit on Wikidata] Elastic fibers (or yellow fibers) are bundles of proteins (elastin) found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle cells in arteries. These fibers can stretch up to 1.5 times their length, and snap back to their original length when relaxed. Elastic fibers include elastin, elaunin and oxytalan.

What is Fibre? Fibre (fiber in the U.S.) comes exclusively from plants; there is no fibre in meat, fish or animal products (including dairy). Fibre is a complex carbohydrate (type of sugar) but unlike other carbohydrates, which are broken down by the body to provide fuel in the form of glucose, fibre cannot be digested by the human body. See our page: What are Carbohydrates? for more information.

Carbon fibers Carbon fibers or carbon fibres are fibers about 5–10 micrometres in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion. These properties have made carbon fiber very popular in aerospace, civil engineering, military, and motorsports, along with other competition sports. However, they are relatively expensive when ...

- An optical fiber (or optical fibre) is a flexible, transparent fiber made of high quality extruded glass (silica) or plastic, slightly thicker than a human hair.It can function as a waveguide, or “light pipe”, to transmit light between the two ends of the fiber. 9. 2  Special-purpose fiber • Some special-purpose optical fiber is constructed with a non-cylindrical core and/or cladding layer, usually with an elliptical or rectangular cross-section. • 3  These include polarization-maintaining fiber and fiber designed to suppress whispering gallery mode propagation.

Elastic fiber Elastic fibers (or yellow fibers) are bundles of proteins (elastin) found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle cells in arteries.These fibers can stretch up to 1.5 times their length, and snap back to their original length when relaxed.lastic tissue is classified as connective tissue proper. The elastic fiber is formed from the elastic microfibril (consisting of numerous proteins such as microfibrillar-associated glycoproteins, fibrillin, fibullin, and the elastin receptor) and amorphous elastin.

Synthetic Fibers and Fabrics Information Synthetic fibers and fabrics are all made from a type of polymer but they each have unique properties and characteristics making them useful for specific applications. The fibers and fabrics may include a variety of materials and may feature a blended, fibrous structure produced by copolymerization. fiber is a hair-like strand of material. They are the smallest visible unit of a fabric and are denoted by being extremely long in relation to their width (at least 100 times longer than it is wide). Fibers can be spun into yarn and made into fabrics. Synthetic fibers are a subset of the larger area of textiles.

- A nerve fiber is a threadlike extension of a nerve cell and consists of an axon and (in some cases) a myelin sheath. There are nerve fibers in the central nervous system and peripheral nervous system. In the central nervous system (CNS), myelin is produced by oligodendroglia cells. Schwann cells form myelin in the peripheral nervous system (PNS).

- Answers. 1  An axon or nerve fiber is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron's cell body or soma. Axons are in effect the primary transmission lines of the nervous system, and as bundles they help make up nerves.

- Profiles of 15 of the world's major plant and animal fibres - many of them fundamental to human society since the dawn of civilization. Natural fibres are greatly elongated substances produced by plants and animals that can be spun into filaments, thread or rope. Woven, knitted, matted or bonded, they form fabrics that are essential to society. Like agriculture, textiles have been a fundamental part of human life since the dawn of civilization.
