Carbon GT mono

Re: Carbon GT mono >>> Materialfrage ???

Hallo Urs,

von deinem beitrag bin ich absolut begeistert. :thumbsup: wobei es mir nicht so sehr um den gt40 an sich, sondern um die fertigungstechnik geht.
ich beabsichtige auch ein historisches (renn)fahrzeug zu reproduzieren & befinde mich derzeit erst im stadium der visualisierung am/im pc.
weiters bin auch ich gelernter tischlermeister mit absolutem hang zu fahrzeugen aller art ( ein albtraum ) :veryangry:
während des gesamten beitrags versuchen die mitglieder hier herauszufinden wie genau der aufbau der carbonteile funktioniert, so auch ich :laugh:
kannst du die genaue bezeichnung der verwendeten materialien, Hartschaumplatten sowie carbonfaser preisgeben, oder handelt es sich um ein *betriebsgeheimnis* ?
derzeit fertige ich lediglich kleinteile für meine rennmaschine aus gfk, anfertigen einer positivform aus polystyrol + abspachteln ect.

ich wünsche weiterhin gutes gelingen und freue mich auf neue beiträge von dir, mfg:2thumbsup:

Hallo
Sorry für die spähte Antwort.
Die Sandwichplatten bestehen aus einem 10mm PVC Kern und sind beidseitig mit 2 Lagen CFK belegt.
Die Verbindungen und Ecken werden dann je nachdem wie stark sie dann belastet werden mit mehreren immer breiter werdenden Lagen verstärkt.
Bei den Hardpoints habe ich zusätzlich Presssperrholz eingelegt für eine lochleibungsverstärkung. An gewissen Orten habe ich noch CFK Roving Stränge oder Kevlar Stränge eingelegt, wie zum Beispiel beim Horizontal Stegwo die Gurten angehängt sind.
Es ist schwierig das ganze zu beschreiben.
Gruess Urs

Hello Together.

I have a question.

Is there someone who knows, does the ZF cableshifter also fit on a ZFQ gearbox?

On the door skin ans an example, how many layers of cloth have you used a what weight of cloth? Also is it just carbon cloth or is a carbon Kevlar mix?
I understand that kevlar takes impacts better than carbon so I was wondering if you would use a mix for the skin.

 

[Urs]

The door has now 4 layers of carbon .on the inner side we do a horizontal wave. construction in carbon kevlar to take the impact.

hi Urs. great to see you are making progress on your project.
i have been looking through the whole thread over again, and i have a potentially stupid question to ask, if that is ok, because i realise there is something i dont fully understand about the way you have built this.

in the very early shots, you show the front portion of the chassis made out of pieces of plywood. e.g. the front bulkhead, footwell, chassis mounting points. then they have been replaced with CF parts. i think you are making them out of plywood to get the dimensions right, then taking it apart, and cutting these pieces out of flat CF panel you have made. then putting them back in place and laminating them together.

i suppose the flat pieces have only a few layers on them, but most of the layers are added after the basic structure is in place.

is that right, or have i missed something important? sorry for the silly question!

Urs, forget the above question. i realise you have effectively answered it already in post #181 just above.

cheers.

here some new pics

I put the inner and outer shell of the doors together and also the dashboard, but i think about to do a new Dashboard, because it has to much bubbles.
Now we screwing in the engine on place.
Thanks to RCR for the nice radiator and Pedals

It's coming along beautifully.

How did you work out how to make sure the chassis would be stiff enough?

 

[Rebeca Lynn]

That is just perfect in every possible way. It will be a stunning car when finished. Great work

 

[Urs]

Hello
Now we fitted the dry sump on the engine and started the oil lining.
I also start to laminate the nose.
here some pics.

 

[Jim Rosenthal]

Is the dry sump tank carbon fiber, too? Don't tell me.....

 

[Urs]

Hello jimbo.

Yes for sure

 

[Urs]

Today we took out the Nose :stunned::blank:
here some pics

 

[Urs]

Hello Together

Now it slowly looks like a real car

 

[Randy V]

[René]

and still lots of work to be done.
