The reason why the car needs to use carbon fiber engine cover after changing the engine is that it can reduce the body weight, improve the starting and acceleration, and reduce the equivalent at the time of impact, that is, the inertia of the car at the time of collision will produce different equivalent due to different weight. The lighter the equivalent, the lower the equivalent. However, considering the problem of material, it is clear that the equivalent is lighter than steel and has higher strength than steel, Therefore, aluminum and carbon fiber are widely used in automobile refitting, which creates another problem. Why not use carbon fiber as the body? Because carbon fiber is not easy to process and the processing cost is extremely expensive. Therefore, the body part adopts aluminum, while the easy to process parts such as machine cover and rear cover adopt carbon fiber.
Is the carbon fiber hood safe?
After soaking in resin, the soft carbon fiber woven cloth can be baked under vacuum and high temperature, which can not only ensure the hardness equal to that of steel, but also its weight is only one tenth of that of steel, which is why it is favored by refitted cars and racing cars. Since carbon fiber can ensure sufficient rigidity, therefore, carbon fiber hood is still very safe. Without considering the cost, is the more the better, and can even be applied to any position of the body?
Of course, the answer is No. the reason is not that carbon fiber is not easy to design in modeling, which requires a lot of time and labor cost, but that the toughness of this material is less than that of steel. Although the rigidity of carbon fiber is similar to that of general aluminum alloy and steel, its biggest weakness lies in the lack of toughness.
As far as carbon fiber is concerned, when it is impacted by external force, the carbon fiber parts will be damaged to varying degrees according to the strength of the impact force. When the impact force is small, the carbon fiber will crack, and when the impact force is too large, the main body of the carbon fiber kit will be broken in a large area, and the edges of the fragments are very sharp.
If the vehicle has a frontal collision, the engine room, as a self damage buffer, will take the lead in absorbing the energy during the impact, and the subframe, anti-collision beam and cover will absorb the impact force in a deformed way. However, due to the insufficient toughness of carbon fiber material, it will not curl up like the metal engine cover, but take the lead in moving backward as a whole, and finally break when the impact force reaches a certain degree.
No matter what degree of collision, the hard carbon fiber hood will move backward and then pierce the front windshield, which will eventually cause injury to the drivers and passengers. When the carbon fiber hood is broken, its edge is like a sharp knife. If it is hurt by these hard and sharp fragments, it can be said to be a near death.
This is why the modification of carbon fiber engine covers has been prohibited in the technical rules of some racing sports. In order to reduce weight, many teams will choose resin fiber engine covers with better toughness. As the hood belongs to the category of fairing, it only needs to ensure toughness and lightweight.
In many cases, the "carbon fiber hood" purchased by car owners is not made of real carbon fiber, but a layer of carbon fiber sticker is pasted on the surface of glass fiber. As far as the material of the hood is concerned, in fact, the glass fiber material can allow small deformation. Although the willfulness is slightly better than that of carbon fiber, the deformation range is less than that of resin fiber, and there are still potential safety hazards in the collision.
In fact, car owners who buy carbon fiber kits are more out of the demand for aesthetics. However, whether they want their car to be more stylish or pay more attention to the advantages in lightweight and counterweight, safety is undoubtedly the first part to be considered. They must consider it carefully before buying carbon fiber kits.
