Carbon fiber  is a polymer of sime form of graphite. Graphite is a form of pure carbon. In graphite the carbon atoms are arranged in large sheets of hexagonal aromatic rings. Carbon fiber is made from another polymer, called polyacrylonitrile, through a complicated heating process. When polyacrylonitrile is heated, the heat causes the cyano repeating units to form rings. As the heat increases, the carbon atoms lose their hydrogens and the rings become aromatic. This polymer constitutes a series of fused pyridine rings. The temperature is then increased to about 400-600Cº. In this way, adjacent strings are joined. This heating releases hydrogen and gives  a ribbon-shaped ring-fused polymer. By further increasing the temperature from 600 to 1300Cº, new ribbons will join to form wider ribbons. This releases nitrogen. As can be seen, the polymer that is obtained has nitrogen atoms at the ends, so these ribbons can join to form even wider ribbons. As this occurs, more nitrogen is r...

 FRENCH COMPANY DEVELOPS CARBON RECYCLING SOLUTION Extracthive  works on thr industralization of the recycling of composite materials, mainly carbon fiber. Mehdi Mahmoundi proyect manager for the technology called Phyre, tell us more about the method ans the applications that could be of interest to the marine industry. Extracthive was created in 2015 as a spin-off of a French Atomic Energy Commision (CEA) project.       Its main activity is the development of innovative and tailored processes for the recycling of industrial waste. Buildings on existing technologies or through new solutions, he gets  the method off the ground in the lab and then helps his client move to industrial scale, either through existing recycling channels or by identifying the players needed to create a new recycling circuit. "In 2019,we acquired a subsidiary specializing in the recycling of abrasives  and ceramics, based in the Vaucluse. The idea is to recycle, separate a...

                                                                        ADVANTAGES  1. Lightweight, carbon fiber is a low-density material with a very high to weight ratio. 2. High tensile strenght, one of the strongest of all comercial reinforcing fibers when it comes to tension, carbon fiber is very difficult to stretch or bend. 3. Low thermal expansion, carbon fiber will expand or contract much less in hot or cold conditions than make materials like steel and aluminum. 4. Exceptional durability, carbon fiber has superior fatigue propeties compared to metal, wich means that carbon fiber components will not wear out as quickly under the stress of costant use. 5. Electrical conductivity, carbon fiber composites are an excellent conductor of electricity               ...

 WHAT IS A CARBON FIBER? Carbon fiber as such, we could say that it is a series of filaments rich in carbon atoms that come together to form a fabric or fabric, giving rise to a material that, in combination with others such as the epoxy queen, allows us to manufacture those parts that we can see in high performance cars.  We can see in F1 cars that there are completly made of fiber carbon because it weigh less and it casue that the cars go faster and give more show for the viewers. WHERE THE CARBON FIBER IS IT USED? Carbon fiber is used in the desing of the automobile industry, in the manufacture of boats, aircraft and spacecraft parts, raising races, bicycle rings, fishing rods, springs for automobiles, masts for ships, blades for windmills. Wind (wind energy), laptop cases, pocket wallets and watchets, etc. In short, it is a material present in almost all manufacturing fields.
