Sequential fork control drum

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Yes, Indeed I have, many, I do need to watermark them first and do a bit more work on them.
The next few bits are suspension Items, Im carrying out cutaway sections of them, that is cut sections of wishbones, and through onto the ti mounts. This way I can learn a lot about their construction, how the ti is tailored to bond with the carbon, what shape it is within the arm, and how the weave is laid over it.
It will also show me just what they are like inside, and what construction method they used, be it two halves bonded, or bottom layer wrapped over top layer, foam core inside, and the lot clamped within a mould.
I read a lot of supposed construction methods about them, but its now time to discover fully for myself just how they did do it.
By polishing all cut edges I make, and studying the carbon under a microscope I will then know all. I know how they may have done it in theory, and have studied composite to ti bonding, but you just cannot beat hands on.
It is a lot of work to display and find all this, which is why I watermark, but I feel its a small price to pay for my findings considering I have to buy the parts too.
I feel compelled to share, given that there are many on here who are also interested, but have not got the time/technique/money to get around to doing this.

I_need_to_know and see it myself, and not rely on hearsay,

Keep an eye out in around a week, thanks guys, and hope you enjoy and learn a bit :idea:

I´m looking forward to it.
Not something you´d try to do with your household hacksaw.. :wink: Are you planning to put it into clear resin and get it grinded down?

I was doing these things more and more by CT -non destructive- and you usually get everything in very fine detail(if the operator of the machine knows his baby )
some companies selling this equipment do actually offer free first sample CFs to interested parties...

Brian.G,

Please take your time. But also please post lots of details when they're ready. The type of F1 component details you are describing is not something there is much public information about.

As a mechanical engineer, I also think it's great to see someone independently doing a methodical, detailed study of a part to learn about it. I hope you learn a lot, and then pass on your observations.

Regards,

By polishing cut edges of the carbon you can also get an idea of the quality of the carbon curing by looking for air bubbles in the laminate under a microscope.

Though I dont think I could bring myself to cut an F1 part. Especially something porn with titanium and carbon together. It would feel like I'm cutting the mona lisa to pieces to see what paint is being used .

Anyway, I'll be waiting for pictures

Marcrush, I know well how to cut ti and carbon, Ive been doing it for some time now. :wink:
Not planning on clear resin no, just the part, cut to display various cross sections.
If you think -non destructive- is the way ahead thats cool. But, you still cannot find any details you can trust on construction, destructive, or non destructive testing. And you just cannot beat looking at the part in the flesh.

Riffraff, Ill take my time dont worry, Ill display all interesting design points that I feel anyone would ever need to know.

Tim, agree on the first bit, indeed.

As for cutting parts, thats the bit I can get over to see what they hold under the skin. There have been many F1 parts made, but just one mona lisa. Having said that, If I was an artist, and owned the mona lisa, I wouldnt see it a problem taking a 2mm square piece from the edge of picture to run some tests to finally unlock the paint combo he used. Its prob a good job Im not an artist 8)

Stay tuned, below is the first item to be carefully dissected

Very cool,

you have anymore info for us on the part? I just bought an front upper A-arm from the 2002 renault. It also has spherical joints on the inboard side instead of flexure joints. I imagine your arm is of the same vintage?

Looks like a front arm al to me. You know if its an upper or lower arm?

no ofence there .cutting it up is cool and will give away a lot of the secrets.
I just wanted to highlight that some things are very visible with CT .air bubbles,
material voids ,i have never seen ct´d Carbonfibre parts ,but I´m confident you would be able to see the strands of the fibres with the correct contrast settings as well.

Tim.Wright (or anyone else),

Are the Ti pieces co-cure bonded or are they bonded in place post cure?

Definately post-bonded. Its common for some small (usually non-metallic) inserts and hardpoints to be co-cured but you can't guarantee location accuracy as the whole laminate moves (in the thickness direction) as is cures. The only part of a composite part you have dimensional control over are the surfaces touching the mould.

Both parts would have the bonding surfaces prepared (grit blasted, sanded or acid etched) and then the bonded assembly would be done in a jig which precisely locates the Ti pieces in the carbon part.

Tim,
I would think going by henkel, and from past experience that the ti is anodised also.
