Marmorini was probably referring to the material used for the crankshaft. Modulus of elasticity (slope of the deformation vs load curve) is what really matters, because, although resistance is very important, deformation is the real problem. Steel is the best possible choice in term of modulus of elasticity and since the more recent steels, though offering an increased resistance, have also a module of elasticity a bit lower that the classic ones, a classic alloy is better in that case.scarbs wrote: Dont forget good old steel ... Luca Marmorini told me they use one steel that dates back to the second world war.!
anyone who knows where kevlar is used, and why it's not very popular in F1?none wrote:If the F1 have so much money why dont they make more parts from kevlar, its strong and light but im not sure if it bends to keep strength, mind you it does have strong H-bonds
beryllium is radioactive. there are 12 different forms of baryllium. the form used by F1 teams did emit x-rays.Gliderpilot wrote:Beryllium (9Be) is not radioactive as opposed to the other isotopes. The problem with that material is that, in a fire, it will convert into beryllium oxide - which is VERY toxic. In case of an engine with beryllium blows up in a race, many many spectators could get very sick.West wrote:Monstrobolaxa wrote:But Beryllium is radioactive....if I'm not mistaken......
Don't forget Magnesium, gold foil (high heat reflectant).....
If it is radioactive, there's still nothing wrong w a Black and Silver and sometimes Green McLaren.

Yes aramid fibres are used in F1, due to their toughness, whereas carbon is primarily used for the high stiffness. Try cutting a piece of uncured carbon and aramid. The carbon cuts easily with a blade or a pair of scissors, aramid is very difficult to cut and will destroy the cutting edges of the blade or scissors very quickly. The haynes book is a great introduction to avdanced composites.Monstrobolaxa wrote:Well Kevlar (also known as Aramid) is used in F1.....Williams uses it in its monocoque.....Kevlar has an advantage and a disadvantage when compared to carbon, that is why teams tend to mix both to get both of the advantages to work in your favour. I don't know the advantages or disadvantages.......but.....I read it in the Competition Car Composites (Haynes Publishing).....but the book wasn't mine....so if someone knows the answer.....
Carbon shatters once it reaches it's breaking point (I forgot all the terms). So w/ aramid (kevlar), it will "stretch" that breaking point a little further?oz_ferrari wrote:Yes aramid fibres are used in F1, due to their toughness, whereas carbon is primarily used for the high stiffness.

Rally cars also use aramid fibres as protective structures such as sump guards, they are good in impact situations,whereas carbon reaches its ultimate strength and then breaks catastrophically. Carbon is brittle, aramid actually yields similar to metals.
I hope that helps
