Carbon fiber

Material

The carbon fiber is a threadlike structure, very thin, made ​​of carbon with which it builds a wide variety of materials called composites because the fibers are "compound" or joined together in a matrix, typically of resin (but may be metal or plastic) whose function is to hold in "pose" resistant fibers (so that they maintain the correct orientation in absorbing efforts), to protect the fibers and also to maintain the shape of the composite article.

For the realization of composite structures the carbon fibers are first twisted together to organize real cloths carbon fabric and then, once placed in laying, are immersed in the matrix. Among its features stand out 's high mechanical strength , the low density , the capacity of thermal insulation, resistance to temperature changes and the effect of chemical agents, good properties fire retardant.

Glass fiber

Material

The glass fibers are used for the production of composite materials or advanced structural materials in which different components are integrated together to produce a material of superior characteristics from a physical point of view, mechanical, chemical, aesthetic , etc.

Common experience teaches that the monolithic glass is a brittle material. If instead it is spun to a diameter of order less than a tenth of a millimeter loses its characteristic weakness to become a material with high mechanical strength and resilience. The fragility of the glass is common due to the large number of defects that act as crystallization and micro areas of stress concentration. On the contrary, fiberglass does not have all these defects, which reaches mechanical strength close to the theoretical strength of the covalent bond.

Kevlar

Material

Kevlar is an aramid synthetic fiber invented in 1965 by DuPont. Its main feature is the great mechanical resistance to traction, so that a given weight is 5 times stronger than steel. The Kevlar also has a high resistance to heat and flame. For its strength is used as a reinforcing fiber in the construction of bulletproof vests, extreme sports equipment, components for airplanes and more recently for sails of the boats racing.

Leather

Material

The leather has characteristics of resistance and especially hygienic very high which make it particularly suitable for the production of many articles of common use. It is known, for example, that leather shoes promote the elimination of perspiration and then avoid the development of fungi , mildew and other diseases of the skin and of the foot produced by the stagnation of humidity inside the shoe. Similarly to other artifacts for human clothing. It is said, in fact, that the leather "breathes" as it leaves from the cross water vapor emanating from the human body.
