History Parker Brothers Ping-Pong game The sport originated in Victorian England, where it was played among the upper-class as an after-dinner parlour game.
Corrosion Resistance Metal-Matrix Composites The improvements that advanced materials have produced in bicycling can be gauged in the enhancement in the Olympic pursuit records.
InDaler won the 4, meters individual pursuit with a time of five minutes, five seconds; inBoardman won the event in three minutes, 22 seconds.
Tennis Tennis is a sport in which absolute achievements cannot be compared. Yet who can argue that Bobby Riggswith his wooden racket, would have no chance against Andre Agassi armed with an oversized composite racket with an enlarged "sweet spot? In the late s, metal frames, generally fabricated from steel or aluminum, were introduced.

|From the field to the composite||Unlike other rackets that are all aluminum or steel and have a "T" connector holding the shaft to the face of the racket, the FiberFlash 7 series of rackets has a beautiful one-piece design with a smooth connection between the shaft and the head of the racket.|
Presently, composite rackets are all the rage both from the viewpoint of efficiency accelerating the ball across the net and in terms of damping the dangerous vibration that can lead to tennis elbow.
The impact force experienced by a player on returning a tennis ball traveling at km per hour is approximately equivalent to jerk-lifting a weight of about 75 kg. These forces can transmit a high load to the lateral epicondyle, located on the outer side of the elbow, leading to damage to the small blood capillaries in the muscles and tendons around the elbow joint.
Better technique can help, but an improved Presentation carbon fibre in tennis rackets can also make a major contribution. The goal in designing modern tennis rackets is to increase the size of the sweet spotthe central part of the racket that leads to little or no shock to the player and where minimal vibration occurs upon impact with the ball.
This depends upon the stiffness of the frame and the size and shape of the handle and head. The International Tennis Federation has now imposed an upper limit in the size of the racket.
Today, tennis rackets are produced from monolithic metals including steel, aluminum, magnesium, titanium, and metal-matrix composites. However, the high stiffness of carbon-fiber-reinforced composites makes them superior to the metals inimparting high forces to the ball.
To reduce the high-frequency vibration upon impact, racket handles are constructed of multiple fiber-reinforced layers wrapped around a soft inner core, which is often an injected polyurethane foam or honeycomb construction.
The graphite provides strength and stiffness, minimizing head deflection, and also helps to prevent twisting of the racket head when the ball impacts outside the sweet spot.
The Kevlar fibers lead to additional strength and durability and contribute to damping vibrations. The fiber FP produces even greater stiffness and damping to this type of tennis racket.
The materials evolution for the golf driver. Golf As with tennis, it is very difficult to compare achievements of the past with those of today in absolute terms.
Clubs have evolved tremendously, and it is difficult to imagine that Bobby Jonesusing hickory shafts, could compete at least in length with John DalyFreddy Couples, or Tiger Woods armed with a shaft constructed from a graphite-epoxy and an oversized hollow titanium head.
At first sight, driving distance would seem to be an absolute criterion that could be tracked versus the material of construction. However, despite checking with the Professional Golfer's Association PGA and various golf magazines, this data could not be obtained it is available for the past few years; for example, John Daly led the way in with an average driving distance of almost meters.
Classification of materials JosepPoch March General classification 5. Modern tennis racquets are made of carbon-fibre composite. Past and Present In prehistoric times metals, polymers, ceramic materials and composites, like the bodywork of a Formula-1 race-car, made or carbon-fibre composite. Past and Present Up to BC: use of.

The carbon fiber found in modern cars and aircraft are typically made from polyarylonitrile (PAN), which is a pricey, non-renewable polymer. "PAN can contribute about half of the total cost of.
A further complication is that balls have also evolved tremendously did you know there is now a titanium ball? The materials evolution for the driver is shown in Figure 7. The overall weight has decreased, and the length of the club has increased from cm to cm. The grip and shaft weight has been reduced from grams down to grams or less.

Carbon fiber tennis rackets are amazing. I figured a carbon fiber sword would be super light and maneuverable. This guy with his carbon fiber lightsaber did not seem too intimidating until this part of . Market Trends: Lightening Up with Carbon Fiber-Reinforced Plastics The market for carbon fiber-reinforced plastics composites is projected to grow % between and , mainly due to demand in the aerospace and defense and automotive sectors.
The weight of the head remains the same at about grams, but by using a hollow titanium casting construction, the head is now much bigger, with the mass concentrated around the outside of the hitting face.
The net result is a club that claims to give greater distance greater clubhead speed because of the longer arc but also a straighter bigger sweet spot shot. Despite this ban in baseball, both new aluminum bat concepts such as the ultralight bat with a double-walled barrel construction and titanium bats are revolutionizing softball.
These bats have bigger sweet spots and lead to greater velocity off the bat. However, the Softball Association is concerned particularly with an increase in injuries to in-fielders who cannot react fast enough to this higher velocity.
Although some examples of the use of advanced materials in sporting goods have been discussed, there are certainly more possible.For example, we have added flax in the following tennis raquet so as to increase the dampening properties of composite parts without losing mechanical performance: The flax fibre can be considered as a complementary fibre to glass or carbon which can bring new properties to your parts and increase the quality of your final products.
Polymer Matrix Composites FINDINGS Polymer matrix composites (PMCs) are com- of polymer-impregnated fiber tapes on a mold Sporting goods, such as golf clubs and tennis rackets, account for another 25 percent.
The sporting goods market is considered mature, with. Every racket consists of a blade and rubbers covering the area that hits the ball. The blade can be made up of one to seven layers of wood, cork, glass fibre, carbon fibre, aluminium fibre or Kevlar.
The material used is specifically chosen to make the ball go slower or faster. The carbon fiber found in modern cars and aircraft are typically made from polyarylonitrile (PAN), which is a pricey, non-renewable polymer. "PAN can contribute about half of the total cost of.
