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]
Carbon fiber sunglasses temples and carbon fiber bicycle frame tube. Carbon fiber can have higher cost than other materials which has been one of the limiting factors of adoption. In a comparison between steel and carbon fiber materials for automotive materials, carbon fiber may be 10-12x more expensive. However, this cost premium has come down ...

For example, carbon fibers are commonly used in aluminium matrix to synthesize composites showing low density and high strength. However, carbon reacts with aluminium to generate a brittle and water-soluble compound Al 4 C 3 on the surface of the fiber. To prevent this reaction, the carbon fibers are coated with nickel or titanium boride.
The components of carbotanium; carbon fiber and titanium, are woven together to form a strong, light material that can withstand significant amounts of heat and strain. This is because carbon fiber has the highest strength-to-density ratio of any current fiber and titanium has the highest strength-to-density ratio of any current metal.
This usage is more common with certain specialty fiber or textile applications. The materials with the highest specific strengths are typically fibers such as carbon fiber, glass fiber and various polymers, and these are frequently used to make composite materials (e.g. carbon fiber-epoxy).
Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
Carbon nitride is only stable at a pressure that is higher than that of the graphite-to-diamond transformation. The synthesis conditions would require extremely high pressures because carbon is four- and sixfold coordinated. [11] In addition, C 3 N 4 would pose problems of carbide formation if they were to be used to machine ferrous metals.
