F1 Plastics selection help
(OP)
Hello,
Im after some advice on plastic selection.
I have designed a device that will be used in all F1 events. The devise will be located in a position that could and probably will receive impact from cars. The device itself is sprung loaded so when it is hit it will retract but it will receive impact from the underside of a car. Initially I selected nylon 66 but am now having some doubts after some testing. The item itself is about 150mm x 15 x 40 an would need to be machined from a block.
One of the main criteria is that the item does not break or crack. It can deform but I do not want it to break.
Can anyone suggest a good plastic that will suit my application.

Polyester based elastomers such as "Hytrel" or "Arnitel" will do better but are quite expensive.
Polyurethane will also do it.
Santoprene or super tough nylons or super tough polyesters might do it.

Thats a start.
Maybe one point I was a bit mis leading with is the fact that the component needs to be stiff, but will not crack or break on impact.

Very tough, abrasion resistant, low cost tooling.
It is almost impossible to machine conventionally, but water jet cutting works fine for profiles from pre-cast sheet/blocks (if your design allows this...), when then you would have no tooling costs as such.

If you're machining out of a block, want stiffness and ductility, then why not a piece of steel? What properties are you looking for that push you towards plastic?

Metal is not an option for me, basically the FIA will ot approve the use of my design if it is from metal on safty reasons.
I guess I want a plastic that I can machine and has the properties that a block of ALI would have but isnt metal.
