J-20 5th Gen Fighter Thread IV (Closed to posting)

It does not prove a relation to J-20. That man could well be acting on his own and for his own benefit.

Of course - he may very well be acting on his own - he is a sports equipment manufacturer and maybe he just want to create the world's lightest and strongest tennis racket that can't be detected by radar!!!! But a tennis racket that will cost more than $100,000 dollars using military grade material? I highly doubt it. Who is going to buy such tennis racket?? Why would anyone need one that strong and can evade military radar let alone airport scanners?? Even Roger Federer will find no use for it. Probably only Marcos Baghdatis need a racket like that!

The problem I have with this case though is that - before this case I don't think carbon fiber he was trying to acquire was actually illegal - they had to indict him on International Emergency Economic Powers Act which basically means they charge him and put him in jail for a crime that he is completely unaware of as the object is NOT illegal previously and only deemed illegal after they perceive it is a threat to the national security. Basically, this can be extraordinary abuse of power in the hands of politician - who can just deem any object as threat to "national security" AFTER you acquire the object unannounced and put you in jail for it.

It seems that people here seems to think ONLY RAM paint is needed to make aircraft stealthy...
So, just to clarify - even early "stealth" aircraft made by the NAZI (that's right, back in WWII!) the fabled Horten Ho 229 was made by laminating wood and a special carbon layer (glue mixed with carbon powder / graphite) to create the airframe body to achieve stealth.

And stealth technology has gone through leaps and bounds - although principle is still the same - the aircraft body (the airframe) needs to be stealthy itself, as with the shaping and that coat of RAM paint.

Also, another thing we can take away from that article is :

"...The Chinese T800 grade will cost only 1,600 yuan ($262) per kilogram..."

Plug in the empty weight of J-20 (19,391 kg (42,750 lb) from wiki) and we get : $5,080,442 USD for the airframe alone (assuming majority of the empty weight is the airframe). But of course the empty weight is not just taken up by the airframe alone - there is titanium composite, and various other components like the radar and the engines which take up significant portion of the weight of the aircraft. I am guessing the production of the airframe will cost in the $3 million USD ballpark.

The U.S. and its allies do not export T800 carbon fiber to China, in order to prevent its use in military aircraft there. In May, a Chinese man pleaded guilty in a U.S. court to trying to take Toray T800 from the U.S. to China."[/I]

yet search T800 on Alibaba and you'll find numerous suppliers of Toray T800 in China.

according this article, rather than spy, just another business man entrapped by outdated export laws.

From what I understand from the article is that China has been able to make T-800 carbon fiber for some time but just only in limited amount. Its only recently that they planned a factory that can 20 fold their production and China is working on T-1000 and M60J carbon fiber. So I believe that the airframe of the J-20 prototypes is made of T-800 carbon fiber.

They could want that carbon fiber for a lot more reasons than the J-20. It's not like the sole use for T-800 carbon fiber is on stealth planes. There are a vast number of other uses for materials like that, even within aerospace.

The carbon fiber that he was trying to get wasn't the T-800 but the M60JB, that's what the F-35 is made of and China currently isn't able to produce yet. But the relations of this case to the J-20 program is highly speculative.

By the way: Where is no. '2013' ???

It is not inconceivable that his intention might well have been to sell to the Chinese government without any collusion with them. There was insufficient prima facie evidence to tie the theft to the J-20 program.

It achieved visual stealth shortly after the grainy photo was taken.

Actually that's just the PLA cover story. Secretly our own Air Force Brat was covertly infiltrated into China by the CIA. he and a support team then infiltrated the PLAAF base and stole 2013 they then flew it to a refueling rendezvous near the Arctic Ice shelf.
