China's 660-MW ultra-supercritical coal power plant is much more efficient and cleaner than traditional ones. It saves 120,000 tons of coal a year and reduce CO2 emission by over 300,000 tones a year.

Hyperspectral camera can provide high resolution images and reveal spectral characteristics of materials invisible to the human eye.

China unveils new hyperspectral camera​

According to Yuan, the hyperspectral camera is capable of splitting light into more than 100 spectral bands, covering wavelengths from visible light (400 nanometer) to near-infrared light (1,000 nm). With a single exposure, it captures 100 continuous spectral channels at a resolution of no less than 1024×1024 pixels, providing highly detailed images and revealing spectral characteristics of materials invisible to the human eye.

Its applications are wide-ranging. In agriculture, the camera can detect early signs of crop diseases and locate toxin accumulation farmlands. In environmental monitoring, it can identify algae blooms, heavy metal pollution, and dissolved chemical substances in water. It also shows promise in sectors such as industrial quality control, medical research, and power line inspection.

Via Cute Orca, supposedly domestic carbon fibre still isn't up to standard compared to even legacy T800 standard, with all the fancy labelling and supposed advances in material science while western leaders are already moving on with T1200 grade carbon fibre production. *sigh* Rather concerning prospect for C929 and next generation military aircraft.

I mean I don't know who the original source is, so this is not all that useful.
There are multiple aspects of T800 and they are not all the same.

But one thing is for sure, they are still importing a lot of T700/800 grade Carbon Fibers, so that means many domestic customers don't trust the domestic T700/800 material. As with everything else, any product takes time to resolve. New products aren't and shouldn't be expected to have as consistent performance level as products produced by a mature process.

Your last comment is just ignorant.

How so? T800 and more advanced composites are being used on modern western airliners like the B787, if China cannot produce comparable alternatives how are they going to compete technologically? and FYI if I remember correctly news of domestic T800 production starting is from all the way back in 2017, not exactly recent or new. You could of course argue that COMAC can use imported carbon fibre material but what about military? Surely, they can't use imported material in that

Uhh T1200 isn’t to my knowledge being employed in any major aerospace applications right now. You don’t need T1200 for a 787 or A350 analogue either. T1200 didn’t exist when they were designed. Don’t take Orca too seriously. They may be in the right rooms for spicy gossip but they’ve shown consistently lackluster technical knowledge.

Yeah, you right about T1200(and even the T1100) isn't used for aeronautical applications(yet), but I'm pretty sure A350-1000 uses some T1000 grade fiber already. But as C929 is meant for first flight sometime around 2030 while the 787 and 350 can be considered 2010s aircraft at best, I think it is fair to expect some kind of material science improvement.

I don’t have time to frankly reply to everything you write about so just read back on this thread please. Plenty of CF related posts here.

this level of ignorance from Chinese netizens actually from a reputable source is shocking for me.. but if you regularly use Weibo and other Chinese social media platform. then you feel this is a daily routine. almost everyone downgrade China's achievement and the irony is, these lazy people don't even check regular updates and news from company just like we do on this forum. majority of these people still stuck in 2000-2010.

i can bet on that, cute orca didn't read about YongCheng New Materials, Guangwei and Zhongfu Shenying latest announcements.

when a company itself saying, our T59G currently verifying in COMAC. then who is cute orca ??

these Four massages i have quoted for you. all are with links. please read this. thanks

YongCheng New Materials/永成新材料 started mass production of YC11S (T1100 level) CF in March. Its phase 1 plant in Shandong started construction in January 2023 for 4000t CF production line & phase 2 for 8000t. By July, its product has been validated and it will be used in high end aerospace, equipment and such.

more on this

YongCheng + Changchun Industrial University worked together to pass appraisal for T1100 CF. Yongcheng has 2 T1100 line. It's YC11G-12K CF was confirmed by 3rd party org to have excellent product stability & consistency. Company has achieved industrial mass production of T700/800/1000/1100 grade CF. It was first established in 2023.

FYI, This T59G is very interesting. If you look at the charts, T55G (which is the original Shenying T800G product) is already at 5900 MPa.

Which if we check Toray's T1000G

or the Guangwei's TZ1000G from chart above.
Is basically Shenying's effort with SYT65. So if 59G sits somewhere between 55G and 65, then it's probably around 6100 MPa, which would be quite high for T800 product. That's more than enough to satisfy the COMAC requirements imo.

The demand for T1000G seems to not be huge at the moment, hence their effort into T1100 next generation. They claim to have developed SYT70/G, which would be world class. But the big question is still who is actually using it.

let me tell you one more thing, these people like ''Cute orca'' are highly trusted source when it comes to PLA and weaponry. but Composite Material comes under civilian category and we have much information available in public.

4-5 years ago, China's CF material wasn't really upto the mark but now situation is totally changed. T700/T800 is in full scale production and T1000/T1100 is in verification.. T700/T800 widely using in all major high tech products. BYD U9 body made with T700 CF.
