I'm doing a research for a university project.
In particular I'm looking for a "commercial" material (so a material that is available on the market or can be home made) that has good thermal insulating properties.
In particular the material has to last for about 300sec in an environment up to 2000C and the inner part of it has to be as cold as possible.
I have to choose parts for something like a satellite that should rotate around the sun or a star.
I did a lot of research and in particular I focus on the NASA projects. I saw a lot of video of them about "insulation tiles" and some other thermal coating but I think a common person cannot buy them or make at home.
I hope that this is the right community where ask the question.
Thank you for your comments.
Are there no other constraints? Yes the material should be as light as possible.
Because then you could just use a very thick graphite (or copper, for that matter) layer, thick enough that after 300 s the inner part still was close to the original temperature. Most likely you want something a tad lighter. I think that the problem is related to the temperature of 2000C on the outer layer, a lot of materials have a melting point lower that 2000C. I was also thinking something like a layer of a very high melting point material covered by a protective coating, the problem is related to the 2000C.
How would you launch your satellite, if you are restricted to things a person can buy or make at home? This is the question that I try to answer with my research, is it possible to build "something like a satellite" with commercial products? My focus is only on the thermal aspects.
Are you thinking about the thermal shield of the satellite? Yes basically a thermal shield, the material should be used to protect the inner part of the satellite from the "heat radiation" which came from the sun, during the takeoff .... The first idea is something that completely envelops the satellite not considering "the engine part". I perform same calculation I find that the most critical condition are: temperature of 2000C for a time of 300s.
Is it going to be in some atmosphere or in vacuum during these 300 s? At the moment I'm considering both scenarios, but I think the most challenging is the one in which there is atmosphere.
