Materials that retain their strength at high temperatures are called "refractory".
Pure carbon compounds -- graphite, carbon fibers, but alas, not diamonds -- stay solid at incredibly high temperatures.
That is why carbon-fiber-reinforced-graphite (RCC) is used on the hottest part of the US Space Shuttle, the nosecone.
RCC retains its strength at 2000°C.
For other refractory insulators and refractory metals, see the links.
