""My understanding of the
technology is that carbon composites are inherently poor armour
materials as they have very poor strain to failure and limited
through-thickness properties to compensate.""

You 're confusing between APFSDS hits and shaped charged hits . Against "low" incoming hard projectile (APFSDS) , slow it down first then deal with it , against "fast" incoming hard (but fluid) projectile ~shaped charges~, use the strongest material first before your steel . A HEAT jet is coming at you many times faster than a APFSDS and the HEAT jet has almost no schock wave (it 's just too fast) . Its main power relies on sheer speed , pushing everything it hits sideways .
When that HEAT jet encounters something harder than it is (carbon composites and hard ceramics like fuzed Quartz) , the jet goes pear shape . It looses all momentum and doesn 't have the strenght anymore to carry on digging into the following HHS steel . That's physics and it works ;-)
I highlighted fuzed Quartz because it is where the secret lies . This is what the classified foam used on the Leclerc is made of , mixed with some elastomere layers , plus some fiberglass based composites plates backed by triple hardened steel .

That new materail is rated as 2.24 times RHA @3:1 ratio . (check that and you 'll be gobsmacked)

""As for the Challenger
2 defeat by ATGM, that was not an ATGM, but an RPG-29, and it wasn't a
turret hit, it was a lower hull front hit. Of the other known CR2
losses, one was a large EFP to the underside and the other a HESH round
hitting an open turret hatch.""

True , sorry :-(
I just forgot about it and pulled it out of my ... bad memory .
It is true that the lower hull of the Chally is rather weak too .

Cheers .

The front hull of the Challenger 2 is relatively weak, mainly because it was designed as a tank that fought from hull-down positions. The side armour is fairly resilient on its own, but has additional applique plates added to it as well. That said, an RPG29 is a monster of a round - cited on Vasilley's site as the most capable of defeating any point on the T90 frontal arc.

""RETRACT that statement as well.""

I will not . I am right and you are wrong . You missunderstood my post . Read it again .

Cheers .

Herald :
""You are getting an education you can take back to tanknet""

Lololol !!!! Good one . Thank you Herald but I 've been in the business since a long time and Tanknet has very little to do with it .
Why do you still talk to me with such hate and such provocation ?

Cheers .
 


I expect you to support your unsubstantiated claims since from a technical standpoint I've  just demonstrated that many of those assertions were sheer fantasy. You FLATLY don't know what you discuss at all.
