Cars and carbon fiber, the "inside story" you don't know
In my eyes, there are three grades of refitted cars
Primary function Party: pursue the improvement of vehicle power function, brush engine computer, improve turbocharging value.
Intermediate control party: focus on the optimization of control function, conditioning shock absorption, replacement of high-function tires.
High grade light weight Party: carbon fiber composite material heavy dependence.
It's not difficult to improve the power of a car, and it's relatively simple to optimize the control function. However, a car with only mechanical structure is dismantled, and it also wants to reduce weight. It's not only complicated, but also more expensive. The complexity and expenditure are mainly reflected in the carbon fiber products.
As a cutting-edge product, we all know that carbon fiber is very light and the cost is very high. What advantages does it bring to cars?
High strength that can't be damaged at hundreds of kilometers per hour
In F1 cars, carbon fiber covers almost every inch of the car. We can see the steering wheel, the aerodynamic package, the suspension link and the single body shell (F1 cockpit) to ensure the safety of drivers.
These carbon fiber products help F1 cars to meet the requirements of lightweight. Its mass is only one fifth of that of steel products. What's more important is that carbon fiber products are not only light in weight, but also better in strength than steel.
In the F1 race, when the car is hit at a speed of more than 200km / h, the car may rush to the wall, or turn over and hit the ground, or collide with other vehicles. The cockpit of the racing car can still be complete without rupture, so as to ensure the life safety of the driver.
In the C-NCAP crash test of civil vehicles, many vehicles still present different levels of safety problems when the test vehicle carries out the crash test at the speed of 50km / h, while F1 racing car can still reach such a standard when it collides at the speed of more than 200km / h, which shows the gap between ordinary metal and carbon fiber products.
Handling and longevity
In addition to F1 racing cars, more and more super sports cars, especially the British super run led by McLaren, also began to choose a lot of carbon fiber composite body, in order to ensure the safety function of the vehicle in the light weight.
And the use of carbon fiber, in fact, there are more aspects of vehicle function improvement. For example, in terms of mobility, lighter components can perform better no matter when the vehicle is speeding up, braking or cornering.
In addition, due to the high strength of carbon fiber composite products, the use of half shaft and transmission shaft can achieve better transmission efficiency. This kind of planning is also used in Giulia and Stelvio of Alfa Romeo. The actual driving can really feel the faster transmission speed.
In addition, carbon fiber is different from metal and has the characteristics of fatigue resistance and corrosion resistance. Under normal use, carbon fiber components of vehicles have a longer life.
However, it should be noted that carbon fiber itself is resistant to high temperature, but carbon fiber products are made of carbon fiber cloth and resin. Due to the different grade and quality of resin, some carbon fiber products made of polyester resin are not heat-resistant and have a pungent smell, and their appearance will turn yellow after use.
Therefore, when purchasing carbon fiber modified parts, we should pay attention to the type of resin in carbon fiber products. The general grade of resin composition in carbon fiber products that can be purchased is cyanate ester resin (mostly used in aerospace and military industry) which is better than epoxy resin and polyester resin.
Exclusive texture, identity mark
Due to the outstanding function of carbon fiber products, and different from the price of mass products, carbon fiber has naturally become the "black gold" in the hearts of car fans. It has also aroused the popularity of people's trend. If you can use carbon fiber in your car, use carbon fiber. Even if you don't have money, you have to stick a fake carbon fiber sticker.
More and more carbon fiber products have changed from useful type to decorative type
