If it can be used in aircraft and car doors to replace steel then I suppose it can even replace steel in construction.

Terrible news for Iron Ore exporters. China can compete with Australia’s Iron Ore and the steel mills they supply with this finished green and cheap material.

China could end iron ore imports and shut down most of their steel mills if they can make 250m tons of this stuff, or 1 billion tons of steel equivalent.

Will be so easy to just replace steel beams with carbon fiber beams? Or are you more talking about a couple of decades in the future.

The Japanese study about the most highly cited papers (top 1%) that was discussed earlier... here's the rankings.

We make fun of India a lot, but they are indeed rising. I'm surprised to see Spain above Japan.
Spain did very poorly on AI paper representation, so I would assume a lot of these papers are in fields like biology etc.

Italy as usual outperforming expectations.

Very surprising considering that most Graduate programs in Japan are almost always hiring paper churners for Professors and Labs.

Japan is a society that has gone utterly and completely into decline. Not just standard "developed country growing slower" type decline but as in "falling behind the rest of the G7" to the extent that if this goes on for another generation or two, Japan will stick out in the G7 as having the lowest per capita income by a substantial margin, despite once having had the highest. It is already competing with Italy for the lowest spot. It may eventually fall out of developed country status. This process started not in 1945 as you would think, but around 1990. And not with a bang, but with a whimper. There was no sudden crash or crisis that predetermined Japan's fate. Rather it has been a slow grind of the decades. For most of the 1990s Japan was still quite an admired society even though the process had already started.

It may be possible to directly replace steel components in construction if this new material can be made to be the same size as existing steel elements, this would likely mean they would have to be hollow.

I think it’s much more likely that this material allows a different style of architecture that just doesn’t have steel beam type or style construction.

For example, a stadiums’ roof could take on a whole new aesthetic if this material was used Instead of steel. New styles, which would by default be distinctly Chinese would be culturally significant also.

Carbon fiber is normally many times the cost of steel though.

i think you should bit more research on Japan and other G7. on paper Germany looks ahead from Japan but internal demographic change in Germany made the society dysfunctional. on top of that Germany destroyed Europe / Turkey by sucking all the best from them and still depended on China/ Russia/Arabs. i am not even going into environmental degradation.
It will be like Japan sitting on top of Korea/Taiwan/Asean and do what ever with there skills, energy supply and finances.
Imagine other G7 countries doing Olympics under Covid.

Once China can scale it up, it might be really interesting what for sort of creative things people can come up with.

Carbon Fiber is weak in compression, strong in tension.
Concrete is strong in compression, weak in tension
Steel is good at both.

Fibers are already used in fiber enforce plastics, the most prominent use of this in major constructions are modern sewage and drainage systems where fiber reinforced polymer pipes are used.

I can see further development in carbon fiber to be used as a tensile reinforcement for reinforced concrete, but the strength, cost and reliability of steel offers strong competition.
