I'm using braided carbon fiber cord as a load-bearing member for open-flame lanterns. The carbon cord is directly exposed to open flame at temperatures that exceed 1500F). The carbon stands up to the heat beautifully, indefinitely, but it's poor abrasion resistance leads to failure over time through regular handling and the fastener interface.
I have already tried several aramids: Kevlar, Nomex, Technora and Conex. All char to disintegration far too easily.
I've also tried several glass fibers of various compositions and they invariably shed harmful/irritating particles.
My revisionary plan of action involves compositing the carbon fibers into an elastomeric matrix. I'm hoping to see a resilient barrier which protects the fibers and helps mitigate/isolate progressive fiber deterioration.
Are there any one/two part elastomer compounds that I can use for this application?
Alternatively, I'll have to look for some other way to accomplish the same cord-like texture and mechanical properties in another way. I'd be open to suggestion for anything of that nature too.
It is very important that the cord be very flexible and resistant to high temperature cycles in the order of 1500F-1600F.
