Hockey sticks today are made from wood, fiberglass, Kevlar/Aramid fiber, carbon fiber, resin and composite. Traditionally, hockey sticks were made out of wood, usually Mulberry wood.
Technology improved as the hockey game grew in popularity, and in the 1990s, aluminum was introduced as a possible hockey stick choice. However, this was quickly reversed once the injuries outnumbered the benefit of increased hitting power. Now, both wood and composite hockey sticks are made with fiberglass, Kevlar Aramid fiber and carbon fiber.
Fiberglass is inexpensive and it is easy to control. When woven together in a thin texture and combined with a resin, it increases strength. It is often applied to wooden sticks. Kevlar Aramid is a fibrous material. It is used in built proof vests because it is strong, but also has an ease of movement or flexibility to it. Carbon is thin and expensive, but is very strong and can help provide a strong power transfer from the stick to the ball in the game.
In the FIH, which is hockey's governing body, both wood and composite hockey sticks may be used. However, wood remains cheaper and has a more natural feel. This leads to a softer feel with the ball, and many hockey players favor this feel. However, wood hockey sticks are made individually and are therefore less consistent in their specifications. Composite hockey sticks are also larger and have a larger power-to-weight ratio.
