Group: Forum Members Posts: 3, Visits: 5	I'm looking for a carbon fibre material upon which to sit materials to be furnaced; what is the maximum working temperature of the carbon fibre sheet or fabric materials? The process currently operates between 900 and 1000 C for several hours, will any of the materials be able to withstand these conditions? Tags carbon fibre fabric processing sheet temperature

I Guess it is extremely difficult to find a resin to stand that high temperatures max 200°C I think Matthieu Libeert Founder MAT2 Composites X Sports website: www.mat2composites.com

I doubt you can use the carbon for long at 1000°C. The bigger problem is the resin/binder anyway. Why not use a ceramic, or simple graphite? Metals should work, too. Unless you look at exotic materials like reinforced carbon-carbon these are the only options that make sense. https://en.wikipedia.org/wiki/Reinforced_carbon%E2%80%93carbon That's graphite with embedded carbon fibers. Expensive, that material might cost more than the oven. Just use the normal stuff I mentioned above.

Gave serious degradation (cracking, shattering) in the H2 atmosphere when in contact with the potassium metal by-products- a known K-catalysed reaction between H2 and C to give methane. Alumina ceramic plate is the next port of call. Thanks all.
