Carbon, or carbon fiber, is a high-strength material, featuring light weight and high strength and stiffness.
Carbon, or carbon fiber, is a high-strength material, featuring light weight and high strength and stiffness. It is based on carbon fiber and polymer resin. For the manufacture of carbon are used intertwined strands of this fiber (the main component of which is carbon), which are located in a matrix of polymeric resins.
The nature of the weave between carbon fibers is important. It identifies not only its appearance but also its strength and technological characteristics.
The following types of weaving carbon fibers in the carbon: plain, twill, satin, sateen.
The distinctive properties of carbon fiber are its low weight and high strength. It is lighter weight than aluminum or steel – in comparison with the first it is lighter by 20%, and the second — on 50%. These qualities make it very suitable for car industry: the advantage of using it is that easy auto allows you to set the motor less power, which means more economical fuel consumption.
However, carbon has some drawbacks, which did not allow him to go into production cars, even though it is used in the automotive industry as the alternative material. First, this is a fairly high price due to high cost of its production. In addition, the production of it parts is a much more lengthy process compared to other materials, which requires very strict adherence to process parameters; their violation has a significant impact on the strength of the resulting products.
The use of parts made of carbon fiber has one drawback — in case of an accident, this material forms a sharp ragged edge and a large number of fragments, making it difficult for it to recover. In comparison, aluminum and steel components are easier to repair.
Another feature of carbon is complex and expensive processing that makes it difficult to reuse.

The characteristics of the material allow manufacture of a lighter and higher strength parts to replace steel. Its scope is quite extensive.
It is used for tuning cars, as well as in the production of racing cars and supercars. The popularity in this field, he won after the positive experience of its exploitation in the defense industry. The lightness and strength of carbon fiber is also very popular in the construction of air and sea vessels, rocketry. In addition, it is used in the decoration of housings of electronic equipment, in the manufacture of strings for musical instruments, medical equipment etc.
– pressing. During the pressing of strands of carbon fiber woven fabric, which are placed in a special form. The latter is covered with a substance that prevents adhesion (wax, soap or silicone grease). Then performed the impregnation of fabric with resin after polymerization, which produces carbon
– contact molding. When slip forming is used, the original metal form (for example, a part of the vehicle) applied on a separating layer and a polyurethane foam. After hardening, the foam is removed and serves as a matrix to which is applied a separation layer; then it is placed the cloth of carbon fiber. Of tissue removed bubbles, she is hardened due to the rolling rolls. After polymerization, getting ready detail of carbon fiber,
– winding. The technology of winding involves the use of a special form (mandrills), which is continuously wound carbon fiber. Before the procedure, the latter impregnated with the resin. After winding, the form is placed in a furnacewhere it is heated and starts the polymerization process. This method is used for the manufacture of cylindrical products, for example, pipes.
