In my eyes, there are three grades of refitted cars
Primary performance Party: pursue the improvement of vehicle power performance, brush engine computer, improve turbocharging value.
Intermediate control party: focus on the optimization of handling performance, adjust shock absorption, replace high-performance tires.
Senior lightweight Party: heavy dependence on carbon fiber composites.
It's not difficult to improve the power of a car, and it's relatively simple to optimize the handling performance. However, a car with only mechanical structure is disassembled, and it also wants to reduce weight, which is not only complicated, but also more expensive. The complexity and cost are mainly reflected in the carbon fiber products.
As the top product of the material industry, we all know that carbon fiber is very light and the cost is very high. What advantages does it bring to the automobile?
High strength that can't be damaged at hundreds of kilometers per hour
In the F1 car, carbon fiber is almost everywhere we can see, including steering wheel, aerodynamic package, suspension link and 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. More importantly, carbon fiber products are not only light in weight, but also better in strength than steel products.
In the F1 race, when the car is hit at a speed of more than 200km / h, the vehicle may rush to the wall, or overturn into 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 have different levels of safety problems when the test vehicle is running at a speed of 50km / h. However, F1 racing car can still reach such a standard when it collides at a speed of more than 200km / h, which shows the gap between ordinary metal and carbon fiber products.
Handling and life improvement
In addition to F1 cars, more and more super sports cars, especially the British super run led by McLaren, also began to use a large number of carbon fiber composite body, in order to ensure the safety performance of vehicles while lightweight.
In fact, the application of carbon fiber can improve the performance of vehicles in more aspects. For example, in terms of mobility, lighter weight can have a better performance no matter when the vehicle is speeding up, braking or cornering.
Moreover, due to the high strength of carbon fiber composite products, it can achieve better transmission efficiency when applied to the half shaft and transmission shaft. This kind of design is also applied to Giulia and Stelvio of Alfa Romeo. They can really feel faster transmission speed in actual driving.
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 grades and quality of resin, some carbon fiber products made of polyester resin are not heat-resistant and have a pungent smell, and the surface will turn yellow after use.
Therefore, when purchasing carbon fiber modified parts, we should pay attention to the type of resin in the carbon fiber products. The general grade of the resin components in the 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 pattern, status symbol
Because of the outstanding performance of carbon fiber products, and different from the price of popular 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 practical type to decorative type, such as Aston Martin D11 logo and vehicle interior panel, etc.
After all, for male car owners, the material of carbon fiber is like a donkey brand bag. It is worth showing off and sharing.
