Never mind

O look a flexi wing thread again

No it's not a flexi wing thread.

It's about a floor that deforms when heat is passing over it.

And it's not something that people think

Yes, there have been talk about it for so many times. Heat the bodywork to make it lose rigidity.

Problem here is, there is no reason to make the floor weaker at all, not to mention you dont really need this fancy stuff since the carbon fibre itself will lose strength due to the heat.

I also thought we all were unanimous about how it is heat shielding, not only here but it is accepted pretty much everywhere as far as I know.

But ah well, that is formule1 magazine, owned by the Sanoma Media Group. Sanoma is a bit of the dutch Fox. only forming stories in such a way to make it look interesting and force an opinion down the throats of people. And if there is nothing happening, they'll try to make something up. And 90% the stuff they write about is incorrect. So with that in mind, excluding the rest, I wouldnt believe this story either way.

Yeah right

Yeah right

no really they are get any panel over its Tg and you can reform it. this is why your article is bs the floor could reset out of position

Yeah I know they can deform any panel. But this is something different.

To be honest, I do find this informative. It's atleast something out of the box instead of the regular discussions.

Thanks for the post remy

I don't think you understand that the BMI resin used to build most the area around the floor is a thermoplastic once you get it over its Tg they changed to a higher temp matl. in germany. How will the floor return to the static position after it cools. If it is infact a thermoplastic meant to deform in that area what puts it back into place.

if you use e.g. shape memory alloys they get back in shape on their own when they cool down.

You don't read.

By adding fiber-optic wires to strengthen in the distortion you would be able to integrate programming without anyone touching it.

The fiber optic wires will make the floor return to it's original form.
This is a known method and it used in lighter airplanes as well.

Read this page http://en.wikipedia.org/wiki/Thermoplastic
it perfectly explaines how a thermoplastic works. When you add some strengthening wires in it it will once cooled return to it's previous state

Yeah right

Almost everything that is injection moulded is made of thermoplastic. The keyboard you are typing in, the case of your phone, the buckets you carry water in.

The epoxy resins used on the carbon fiber parts on the other hand are not, those are thermosetting resins, and the result of heating is irreversible.

You are talking about thermosetting materials. Link
Thermoplastics are completely different
Read this Link
Then you know the difference between those materials.
