The article touches on potential to use instead of steel, perhaps even in buildings. But I imagine its heat tolerance would likely kill any chances of that, no?

- throwaway4aday 5y agoIt's potentially a thermoset plastic in which case it should be able to resist somewhat high temperatures (maybe 300C). So not fireproof but not terrible either.
- cbg0 5y agoAs a comparison, various types of insulation are rated for 60/90 minutes at 1000 degrees Celsius, while some types of brick are rated for 180 minutes. If this material can't sustain similar temperatures, it's unlikely it will be used in construction.
- ngngngng 5y agoCan I ask how you know these things? Materials science is pretty far outside my area of expertise but I'd love to get a basic understanding of it.
- cbg0 5y agoThere are a bunch of standards for material fire classification, which may differ from country to country, but they're not really available to read online for free most of the time. You can do some googling around A1 fire classes, EI fire rating and so on. A useful thing to know is that a house fire revolves around 800 degrees Celsius typically, so you should expect various materials that have a fire resistance rating to take more than that for a sustained period.
- AnimalMuppet 5y agoWait, what happens to brick after 180 minutes at 1000 Celsius? I assumed they would either burn or not burn, melt or not melt.
- cbg0 5y agoIt's just one standard, it doesn't mean anything happens to the brick, they probably just stopped testing at that point.
