Then there is the suspension. The team will abondon the hydraulically linked suspension for something more simple and workable. This is where Aldo Costa comes into play.... He has a reputation as a great mechanical designer as we saw in the Ferrari F10.
Do you think the material "Zylon" will play a part in the W04's FW makeup (Zylon cabling inside the FW pylon).
I must admit have heard Zylon mentioned here before but I don't remember what it is.
Ah! according to Wikipedia, F1 Regulation requires that Zylon fibres are used as a shrapnel absorber in the chassis (where you would have Kevlar I guess), for the same in at the crown of the driver's helmet and for use as the rope in the wheel tethers.
Now for cabling in the front wing... The Youngs modulus of Zylon is 250 GPA according to wiki. That is actually 50 GPA more than steel. It's harder to stretch for the same cross section than steel.
But I think you are interested in allowing the wing to move? Like on a hinge? Is that what you were thinking?
Your wing movement would be so small at about 5mm, that you might not need a long cable.
The rules state that mechanical moving parts are banned. (pulleys, moving cables (like a tug rope), linkages etc) So if you were thinking of stretching to allow flexing It would have to be a part disguised as a bolt or a simple stud to make it pass as a non-moving part. The cable cannot have mechanical movement (like the driver pulling on a cable) thought it is legal for mechanics to adjust such a part in the pits (Mclaren brake ducts).
IT's very likely that Zylon could be used as a tension cable, but do you know how it responds to fatigue? It's so stiff that you will only need a zylon string to hold up the wing and to get it move that 5mm, which is a big ask. It might work better off with a more elastic material.
