Does anyone need 1mm/2mm carbon fibre sheet?

Hereís the background.
I was talking to someone knowledgeable about such materials (a friend and aeromodeller since childhood).
He visited me this last weekend, and brought some CF sheets he made for me.
(Heís not an amateur, he has a composites manufacturing company)

Heís been persuading me to build a fuselage in CF instead of balsa.
He recently build a pod and boom fuselage in CF (wing cores from Gaurav Agarwal of Vortex-rc)

I Googled Carbon Fibre Sheet, and found on Amazon that 300/100/1 mm sheet cost over Rs 3000!
Thatís 12Ēx4Ē, or about Rs 60 per sqin! Thatís VERY expensive.

Attached is a pic of the sheets.
If there is a demand, Iíll work out prices and post on the Sales Board.

Hi KK sir,

There is plenty on requirement for CF sheets or tubes in India and also CF engraving. Posting them in sales board would really benefit many enthusiasts who are interested in building UAV frames out of CF.

One of my friend is actually looking for both sourcing and engraving of CF sheets. I will post him the same.

If the prices are in comparable(~50% more) than Chinese websites then that would be profitable in India.

@balakrishna reddy sir,

Thanks for your response.

Since Iím only into fixed wing airplanes, I didnít realise that UAV frames means parts for quads and hexacopters!

What is it that drone builders need in carbon fibre?
Arms for quads/hexas, centre pieces, and undercarriage legs?
Or just plain rigid sheets of 1,2,3mm ?

Whatís engraving? Cutouts in parts?

Thanks for your interest and help.
Regards

Sorry for being unclear.

Yeah I meant multi rotors only.
A racing quad(200 to 250mm) is almost completely made of CF sheets of varying thickness. Arms are made mostly from 5mm sheets. Centre plate made of 2 to 3 mm sheets.

If the person you are talking about makes tubes then that would be an advantage for bigger size quads from ~450mm and above. Round tubes are most welcome. Centre plates of bigger size quads is also made from 1.5/2mm CF sheet mostly. Motor mounts are also made from the same.
So I was thinking if the same person makes CF tubes also he/they can become one point contact for most required materials for custom multi rotor builders.

I would like to buy some if the prices are reasonable. Need them for my next multirotor.
Even Tubes are very expensive in India, and they sell pultruded ones, which are no good. Need the proper woven type tubes, 14-16mm dia ones.
Try to ask him if he makes those as well.

If Cutting/engraving is needed, I have access to an abrasive waterjet cutter but need to enquire about the pricing, but it would be cheaper than market, as it is provided by my college.

I have 3 sheets of about 18Ēx14Ē (46x34cm or 1564 sqcm)
2 are about 1mm thick, one is 1.5 or 2mm.
A friend made these for me, but I donít have any use for them currently.

On Amazon I see 30x10 cm of 1mm sheet costing Rs 3000.
Thatís Rs 10/sqcm.

That makes one of my sheets worth Rs 15,640!
Thatís crazy.

So if someone tells me what the true market price for a 1mm CF sheet is, I could offer a significant discount...

Hello Mr. Iyer,
 I just came across this post. Do you still have the 1mm and 2mm Carbon Fiber sheets? Also, if you are selling, what is the price?
