What is a carbon fiber hood?

Carbon fiber is a microcrystalline graphite material obtained by carbonization and graphitization of organic fibers. The microstructure of carbon fiber is similar to artificial graphite, which is a messy layer graphite structure.

Carbon fiber is a new material with excellent mechanical properties, its specific gravity is less than 1/4 of steel, the tensile strength of carbon fiber resin composite material is generally above 3500Mpa, which is 7~9 times of steel, and the tensile modulus of elasticity is 23000~43000Mpa, which is also higher than steel. Therefore, the specific strength of CFRP, that is, the ratio of the strength of the material and its density can reach 2000Mpa/(g/cm3) or more, while the specific strength of A3 steel is only 59Mpa/(g/cm3) or so, and its specific modulus is also higher than that of steel.

Why the head of the AE86 in the D to replace the engine with carbon fiber hood, is because it can reduce the weight of the body, and improve the start and acceleration, and reduce the impact wh

en the equivalent of the car collision inertia because of the weight of the different equivalents, the lighter the equivalent of the lower but also take into account the issue of material, the above has been said very clearly the equivalent of lighter than steel has a higher strength than steel, so Aluminum and carbon fiber are used in a large number of car modifications, which raises another question. Why not use carbon fiber to do the body, because carbon fiber is not easy to process, processing costs are extremely expensive. So the body part of the use of aluminum, while the hood and rear cover and other easily processed parts using carbon fiber. (But I guess the head text D did not consider the safety issue it).

1, carbon fiber material, light and hard but expensive

The carbon fiber material used in the car body, seen more is less need to consider the cost of racing cars and supercars (and some expensive electric cars as a gimmick). The purpose of using carbon fiber in cars is to reduce weight and to improve the appearance. In layman's terms, carbon fiber is lighter than steel and harder than steel, so it is a great tool for weight reduction in cars. But its biggest problem is that it is expensive, so it is not yet popular on ordinary civilian models, the application is more racing cars, high-end luxury cars, supercars and other models.

2, love carbon fiber, car owners to change the front cover

Body weight reduction to enhance the dynamic performance of the car has a great help (imagine that generally speaking fat and thin than, who is more flexible), so many car owners fell in love with carbon fiber, find ways to use carbon fiber on the body. Currently seen more is the carbon fiber front cover, such as the following Ford and Mazda owners, the original front cover replaced with a carbon fiber front cover. Changing the carbon fiber front cover, in a certain degree to reduce the weight of the car; but also make the car looks more sporty (good-looking and difficult to see depending on the person). However, the disadvantage of carbon fiber front cover is the high price, most of the market more than 2000, some even tens of thousands, in order to spend thousands of dollars for this little weight reduction, the average car owner is not really happy. So there is a low price, the so-called carbon fiber film this thing.

3, the real thing is too expensive, the owners of the whole look like goods

Some car owners in order to make their cars look like installed carbon fiber front cover or because the front cover scratched do not want to repair, go to the front cover sticker carbon fiber film, hundred and eighty dollars for a "carbon fiber cover", this pretend X to 100 points. (However, I do not recommend that you do so, because according to the regulatory requirements, the body of a large area of film must be declared for the record, otherwise it can not pass the annual inspection. Unless looking for ......)
