A recent example of testament to the F-35 'stealth coating' is of course on another thread so go there: [other threads also]

viewtopic.php?f=60&t=53014&p=428988&hilit=Waldron+rock#p428988
"...the coating itself is “rock solid”. “It’s a generational jump from previous stealth aircraft,” he says. Lockheed’s F-35 factory in Fort Worth, Texas, has a doormat made from the jet’s low-observable skin. “Every year they pick it up and check it, and it still holds that LO quality,” Sheehy says. Steve Over, director international business, adds: “It’s seen tens and tens of thousands of steps. People jump on it, stomp on it... it’s just one thing we use to prove the durability of the coating system.”

More importantly, they contend, the coating is easily applied in the field and requires no environmental control facility as with previous versions of stealth aircraft. Lockheed says the interval between maintenance events for the F-35’s low-observable coating is now 19h – better than the targeted 9h...." https://www.flightglobal.com/news/artic ... id-461721/

"....For those services that operate airplanes in more benign environments than an aircraft carrier, they’re getting the benefit of a coating system that’s designed for an aircraft carrier. Everybody gets the same thing...."

Could someone explain the differences in composition between the F-22 and the F-35 coatings? Why two primers on the F-22? What does the conductive coating do? What is the waterborne primer? The fibermat?

A 36 page PDF (reprinted hence PRN - URLs not live) about some aspects of how F-35 STEALTH achieved is attached below.

Using the SEARCH function one may find 2 pages of references to 'fibermat' (which is likely also 'fiber mat'/'fibre mat').

ONE example: viewtopic.php?f=58&t=19506&p=229846&hilit=fibermat#p229846

Gums... you just wanna tear by that Florida State Trooper whilst his radar gun reads 0 mph... (If you somehow add the APG-81 to the hood, then you could get his gun to read 55 mph, or whatever you wish.)
Take an F-16, stir in A-7, dollop of F-117, gob of F-22, dash of F/A-18, sprinkle with AV-8B, stir well + bake. Whaddya get? F-35.

Thanks. What a hassle PPTs are these days for someone without MS Office or a PPT Viewer. I'll see if I can make a PDF.

Official MS PPT Viewer said file was corrupt so from screengrabs a 10 page PDF made with 'question' blank page deleted.
