Pole figures displaying crystallographic texture of gamma-TiAl in an alpha2-gamma alloy, as measured by high energy X-rays. [1] In materials science and related fields, crystallographic texture is the distribution of crystallographic orientations of a polycrystalline sample. A sample in which these orientations are fully random or is amorphous ...
Carbon fibers or carbon fibres (alternatively CF, graphite fiber or graphite fibre) are fibers about 5 to 10 micrometers (0.00020–0.00039 in) in diameter and composed mostly of carbon atoms. [1] Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high ...
Forged composite, commonly referred to as forged carbon, is a type of carbon fiber SMC material composed of small pieces of carbon fiber composite material that are pressed into shape as the resin sets. This is in contrast to most carbon fiber composites, which are made of larger continuous layers that are 'laid up' one at a time, often manually.
Controversially, in 2006, cricket bats with a thin carbon-fiber layer on the back were introduced and used in competitive matches by high-profile players including Ricky Ponting and Michael Hussey. The carbon fiber was claimed to merely increase the durability of the bats, but it was banned from all first-class matches by the ICC in 2007. [37]
Twaron (a brand name of Teijin Aramid) is a para-aramid, high-performance yarn. [1] It is a heat-resistant fibre, helps in ballistic protection and cut protection. [2] Twaron was developed in the early 1970s by the Dutch company Akzo Nobel's division Enka BV, later Akzo Industrial Fibers.
The process by which fibers become yarns and yarns become fabric results in fabric structure and its properties. [5]: 52 Other than the hand feel and texture of the fabric, the frictional properties of the fibers and comfort to the skin are properties of the fabric that depend upon the surface contour.
The fabrication process includes thickening of continuous carbon nanotube films by gas-phase pyrolytic carbon deposition and further graphitization of the carbon layer by high temperature treatment. Due to the epitaxial growth mechanism, the fiber features superior properties including low density, high mechanical strength, high electrical ...
Orienting and aligning these crystalline regions gives further strength to the fibers, specifically if the orientation is along the fiber axis. Carbonization and graphitization are the two processes responsible for this alignment of the crystalline regions. Pitch based carbon fiber is lower in strength than fiberglass; however, it has a very ...
