Tennis was first proposed by the 11th century invention of the French missionaries, the first racket very "amazing" - that is, those

who play their own hand. After all, the meat can be done manually, after a period of time, some can not stand over the ball every time

the palm of your hand will be red and swollen people who designed an exclusive tennis gloves. But the real sense of the racket has

been to the year before the 14th century came to this world, its design is an Italian.

This is a legendary racket do with wood frame, using the intestines of animals shot string to do. Grip the racket for a long, and the

most critical parts - the first shot is tiny, similar to the proportion of the entire racket squash rackets today. However, even in

modern people think that is a very simple and ridiculous racket, the tennis courts at that time also all the rage. Until 1874, the

British Walter C Wenger beat created by Rumsfeld to establish a standard of modern tennis rackets. Since then a century of tennis

competition, people are waving the wooden racket. May cause headache, the wooden racket indeed spend less effort to hit a more

aggressive pumping hit, but it is difficult to control the precision shots.

Then, gradually replaced the wood-metal racket tennis racket. The first truly popular metal racket by Wilson sporting goods company

produced in 1967, the shape of the light at the time the French legend Gene Lacoste players have used a wooden racket, at first glance

to like ice cream cones.

In addition to metal racket material changes, the ball area of the wooden racket than twice the increase to give the players a greater

degree of freedom ball and allow them to quickly improve the technology. In addition, the metal bat is not easy to crack and break.

The history of Grand Slam final in a wooden racket used in the Columbine Kevin, in the Australian Open in 1984, the disastrous defeat

at the hands of the opponent to take pictures of aluminum alloy.

Today, the production of tennis is dominated by composite materials, such as carbon fiber, glass fiber, Kevlar fiber, high-tension

carbon fiber, titanium, super-rigid carbon fiber and so on, these materials may be used alone or mixed use. Than with wood or

aluminum, and they seem lighter and more rigid, more durable and better able to absorb shock and vibration. These materials also allow

manufacturers of hardness in the racket, the ball is a sense of hitting the performance of the design of the extension of greater

space.

Which is, of course, have to mention carbon fiber and plastic mixture, this mixture of strength and rigidity in the plastic and

aluminum alloy can be of a higher, and weight is greatly reduced.

Successful manufacturers in this very small proportion of the mixture with the titanium with a tennis racket manufacturers, known as

carbon film. Once, this racket than any of the rackets are light, easily allows players to play the greatest force on the hand and

racket of the flexibility inherent in allowing a more increasing the effective hitting area.
