@Konjaril : I must say the car looks super mean and too good in the pics you have posted.
Secondly- As per my knowledge the main components of a car body are frame (which is fastened to the car chassis), chassis and then comes the skin (Exterior Panels).
Following is the process when a car undergoes a accident or a impact.
- The impact of accident (Shock waves) is taken by the car skin (If the impact is more it gets deformed permanently)
- If at all the impact is more, the shock waves get transferred to the frame, suspensions and to the chassis.
- When the impact reaches the frame and the body, then it is felt by the passengers in the car (It is applicable to all the cars weather it is Corvette , BMW, V8 Engine or V12 Engine ).
In your case, what will happen is . As soon as there is a impact, this will be directly taken by the frame and the chassis. The reason being the toughness and brittleness of the car skin. The skin will not absorb the shock waves and will transfer them to the frame and chassis (Which can be fatal at times).
Note:- Brittle material will always transfer the shock waves and malleable material will always absorb the shock waves.
Now coming to Corvette . Yes the Corvette is made of composite of fiberglass and polycarbon material. Corvettes have some mixing of other materials, such as the ZR1’s carbon fiber hood. In the case of an accidents with corvettes, you will always see that the skin is affected and not the frame of the car. The reason for the frames remaining intact, is the grade of fiberglass thickness used. The fiberglass skin used on the Corvettes cannot take higher intensity shocks and that is what I am trying to explain you. There is no problem in making the car skin with a fiberglass. The problem lies in making it extensively tough.
As shown in your video:- As soon as you hit the bonnet with that hammer, you can see the vibration of the impact on your fenders too(The brittle material will always transmit the shock waves , instead of absorbing and reducing them). Hence after fitting these parts to the frame it will transfer a large amount of shock to the frame and chassis. Instead if you have a metal bonnet, it will get deformed and will not transmit the shock wave(or will transfer a small amount of impact, which will be very minor) to the frame and chassis.
Hope you take it in a constructive manner and not as a criticism.

Also the body is tough but its flexible too look closely in the video, well if it was recommended that the car should be manufactured by such a material that it can take the impact and get deformed, corvettes ,TVRs , alfa romeos etc would not be even produced and i am not talking about small cars, these are all hairy chested v8 engined cars.
Also carbon fiber reacts the same way in a crash according to my knowledge, its the weaves that holds the whole panel together in a crash and doesn't just disintegrate.
its the main chassis structure in the car that takes the impact. to put a clearer picture, BMW itself has worked on a car, GINA in which they very clearly and boldly state its made of a cloth like material and in a crash its the internal structure that takes most of the impact, So if BMW can do something that crazy we can too i guess.
@CD yes that workshop belongs to Nigel and i work with him, I am an automobile designer. Also manufacturers if u want to know did start taking fibers seriously the only thing is that they perfected it, its Carbon Fiber, which itself is matt and epoxy resin. The technology at the point of time is very expensive and it will slowly and definately catch up. |
