Fiber-reinforced composites are composed of axial particulates embedded in a matrix material. The objective of fiber-reinforced composites is, to obtain a material with high specific strength, high specific modulus, high strength, and high elastic modulus for its weight. The strength is obtained by having the applied load transmitted from the matrix to the fibers. Hence, interfacial bonding is important.Classic examples of fiber-reinforced composites include fiberglass and wood.A commonly used glass fiber composition for structural composites is E-glass, in which E stands for "electrical type". It is a lime-aluminum-borosilicate glass with zero or low sodium and potassium levels. It is popular because it has chemical durability. A more advanced and expensive fiber is S-glass, a magnesia-alumina-silicate glass that is used for high-strength applications.
There are three types of fiber geometry:
There are 2 different geometries for aligned fibers:
Racing cars used to be made of the same sort of materials as road cars that is steel, aluminum and other metals. In the early 1980s, however, Formula 1 underwent the beginnings of a revolution that has become its hallmark today: the use of carbon composite materials to build the chassis. Today, most of the racing car chassis - the monocoque, suspension, wings and engine cover - is built with carbon fiber.
The first step along the way to making a carbon fiber car looks more like a clothing factory than a car factory. In each Formula 1 team factory is a room with large tables on which vast sheets of what looks like cloth are laid out and cut to size. Taken from large textile-like rolls, these sheets are highly pliable, flexible, and unlike textiles, will end up looking nothing like their original form.
Once the material is cut out from the cloth-like roll, it is taken to a design room and placed into molds. The position of the cloth within the mold is important, as it...
