Application of CFRP in Sports Equipments

In high-end sports equipments carbon fibre reinforced polymer has found perfect due to its light weighing property in compare to aluminium or steel. Racing bicycle is the thing where it is used widely. It produce bicycle tubing of less weight.

[1. German bicycle manufacturer Canyon Bicycles GmbH, has developed a racing bike chassis of carbon fibre reinforced polymer with the Institut fuer Verbundwerkstoffe (IVW).
The lightweight Carbon Ultimate F10 bike boasts a total weight of only 1260 grams (for the frame and fork) and its high stiffness for the first time exceeded the cyclists magical limit of 100 of the stiffness to weight ratio, the so-called STW-coefficient. 

The Carbon Ultimate F10 chassis received the coveted red dot award, the international trademark for quality of design, in the red dot design award 2005, one of the largest design competitions worldwide with more than 4000 applications from 40 countries.]
The choice of weave can be carefully selected to maximize stiffness. The variety of shapes it can be built into has further increased stiffness and also allowed aerodynamic considerations into tube profiles. Carbon fiber reinforced polymer frames, forks, handlebars, seatposts and crank arms are becoming more common on medium- and higher-priced bicycles. Carbon fiber reinforced polymer forks are used on most new racing bicycles.

Other sporting goods applications include rackets, fishing rods, longboards and rowing shells. Sports shoe manufacturers may use carbon fiber as a shank plate in their basketball sneakers to keep the foot stable. It usually runs the length of the sneaker just above the sole and is left exposed in some areas, usually in the arch of the foot.

Carbon fiber reinforced polymer is used extensively in high end automobile racing. The high cost of carbon fiber is mitigated by the material's unsurpassed strength-to-weight ratio, and low weight is essential for high-performance automobile racing.
