Carbon grid is a carbon-based woven fiber used in building construction as a reinforcing mesh, replacing steel mesh or rebar. It is also used in aircraft, ships, and automobiles. The material is a composite of plastic compounds, fiberglass, and carbon, known as carbon fiber reinforced polymer (CFRP). Carbon grid is used to reinforce completed structures, such as bridges, and has shown up to 420% greater strength. Its initial high cost has decreased, making it more accessible for everyday construction use. However, it does not have the same yield characteristics as steel, requiring adapted construction methodologies.
A carbon grid is a form of carbon-based woven fiber that is used as a reinforcing mesh in building construction, such as in concrete, where it can replace steel mesh or rebar. It offers advantages over traditional steel reinforcement in that it can be placed much closer to the surface of a material and is lighter in weight. While concrete reinforcement is the primary area of use, carbon grid is also used in many other types of building materials as well as structural components for aircraft, ships and automobiles. Another application of the carbon fiber grid is the use of the material as a reinforcing agent in the design of ion engines, which reduces the weight of such spacecraft engines and increases their thrust capacity.
The material used to make a carbon grille is more than just carbon itself and includes what is known as fiber-reinforced polymer (FRP), a composite of various plastic compounds such as polyester and epoxy, along with fiberglass and carbon. Other synthetic fibers besides just glass fiber are also used, such as aramid, a name derived from the words “aromatic polyamide.” Aramid is a key component of armor and ballistic armor for military vehicles. This combination of fibers and plastics along with carbon is often referred to as a carbon fiber reinforced polymer (CFRP).
One of the key areas of the industry where carbon grating material has become a crucial element is the maintenance of bridges. Bridges composed of steel-reinforced concrete when built are subject to corrosion over time, which can make them vulnerable to excessive stress during weather events such as storms and earthquakes. Steel mesh as an external bracing mechanism has also proven to be of limited value. In this application, the carbon grid is not embedded in the concrete of the bridge, which has already hardened, but is used as an outer fabric wrap to reinforce the completed structure. Regions where carbon grating has been used to reinforce bridge columns since 2003, such as Florida in the United States, have shown up to 420% greater bridge column strength than before carbon meshes were applied. reinforcement of any kind.
In the 1980s, carbon grid material began migrating into the commercial sector from aerospace and military applications. Its high initial cost made it prohibitively expensive for everyday construction use, but, as production volume increased, prices fell. It is now used to reinforce ornamental concrete planters and other heavy, non-essential products in the consumer market. One major disadvantage of fiber composite in building construction is that it does not have the different yield characteristics of steel under stress or changing climatic conditions, so construction methodologies have had to be adapted to accommodate this change when it is used.
