Composite Baseball Bat
Composite baseball bats, opposed to aluminum or wood baseball bats, incorporate a reinforced carbon fiber polymer, or composite, into the bat's construction. This composite material can make up all or part of the bat. Bats made entirely of this polymer are referred to as composite bats. Bats which only incorporate a portion of polymer (and the rest either wood or an aluminum alloy) are referred to as composite hybr Composite bats can also be constructed to improve their trampoline effect over time. That advantage, namely the improved trampoline effect over a break in period, put the use of composite bats under further NCAA scrutiny during the 2009 NCAA Division I baseball tournament. Composite bats, tested after they were already broke in, showed performance standards well beyond the accepted ball exit speed ratio (BESR) Test.

Aluminum Alloy
An aluminium alloy (or aluminum alloy; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', Arnold, 1995 Alloys c ...

Baseball Bat
A baseball bat is a smooth wooden or metal club used in the sport of baseball to hit the ball after it is thrown by the pitcher. By regulation it may be no more than in diameter at the thickest part and no more than in length. Although historically bats approaching were swung, today bats of are common, topping out at to . Terminology A baseball bat is divided into several regions. The "barrel" is the thick part of the bat, where it is meant to hit the ball. The part of the barrel best for hitting the ball, according to construction and swinging style, is often called the " sweet spot." The end of the barrel is called the "top," "end," or "cap" of the bat. Opposite the cap, the barrel narrows until it meets the "handle," which is comparatively thin, so that batters can comfortably grip the bat in their hands. Sometimes, especially on metal bats, the handle is wrapped with a rubber or tape "grip". Finally, below the handle is the "knob" of the bat, a wider piece that keeps t ...

Carbon-fiber-reinforced Polymer
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addit ...

NCAA
The National Collegiate Athletic Association (NCAA) is a nonprofit organization that regulates student athletics among about 1,100 schools in the United States, Canada, and Puerto Rico. It also organizes the athletic programs of colleges and universities in the United States and Canada and helps over 500,000 college student athletes who compete annually in college sports. The organization is headquartered in Indianapolis, Indiana. Until 1957, the NCAA was a single division for all schools. That year, the NCAA split into the University Division and the College Division. In August 1973, the current three-division system of Division I, Division II, and Division III was adopted by the NCAA membership in a special convention. Under NCAA rules, Division I and Division II schools can offer scholarships to athletes for playing a sport. Division III schools may not offer any athletic scholarships. Generally, larger schools compete in Division I and smaller schools in II and III. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hillerich & Bradsby
Hillerich & Bradsby Company (H&B) is an American manufacturing company located in Louisville, Kentucky that produces baseball bats for Wilson Sporting Goods, which commercializes them under the "Louisville Slugger" brand. The company also operates the Louisville Slugger Museum & Factory in downtown Louisville, and produces gloves for sports such as golf, cycling, fitness, and gardening under the "Bionic Gloves" brand. Until 2015, H&B owned the "Louisville Slugger" brand. In that year they sold it to Wilson, although their factory still makes the actual baseball bats bearing that name. History J. F. Hillerich opened his woodworking shop in Louisville in 1855. During the 1880s, Hillerich hired his seventeen-year-old son, John "Bud" Hillerich. Legend has it that Bud, who played baseball himself, slipped away from work one afternoon in to watch Louisville's major league team, the Louisville Eclipse. The team's star, Pete "Louisville Slugger" Browning, mired in a hitting slump ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USA Baseball
USA Baseball is the national governing body for organized baseball in the United States, and is a member of the United States Olympic Committee and the World Baseball Softball Confederation.

Elastic Collision
In physics, an elastic collision is an encounter (collision) between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy. During the collision of small objects, kinetic energy is first converted to potential energy associated with a repulsive or attractive force between the particles (when the particles move against this force, i.e. the angle between the force and the relative velocity is obtuse), then this potential energy is converted back to kinetic energy (when the particles move with this force, i.e. the angle between the force and the relative velocity is acute). Collisions of atoms are elastic, for example Rutherford backscattering. A useful special case of elastic collision is when the two bodies have equal mass, in which case they will simply exchange their momenta. The ''molecules''—as dist ...
