Does the Abrams have a spall liner? No from what I could find

There is no disclosure on the spall lining for the Abrams. Its armor is still classified.

A lot of references to Abrams program in this document in the footnotes about spall liner design.:

https://apps.dtic.mil/sti/pdfs/ADA065838.pdf
‘(Note that no current tanks have spall liners; the proposed XM-1 does.)’

‘As a result, the design of the XM1 included lower vehicle profile, armored
bulkheads between the crew and fuel cells, ammunition storage behind armored doors, blow-off
panels in the turret roof to vent explosions up and away from the crew and a spall liner and
Halon fire extinguisher system.’

Here they mention Permali spall liners able to be integrated in a sandwich format, included in insulating layers.:
https://www.armscom.net/products/spall_liners_by_permali_gloucester

This shows ballistic glass design, with hard-soft-hard layers still providing good results to prevent spalling and maintain adhesion, despite a hard and potential spall risk layer on the backside. This is glass meant to be shot.:

Naval ships have anti-fragmentation between metal layers, the metal walls on the interior aren’t an issue.

Even naval armor plates can be designed to mitigate spall, despite being entirely metal.:
KCA retained the hardened face of Krupp armour via the application of carbonized gases but also retained a much greater fibrous elasticity on the rear of the plate. This increased elasticity greatly reduced the incidence of spalling and cracking under incoming fire, a valuable quality during long engagements. Ballistic testing shows that KCA and Krupp armour were roughly equal in other respects.[2

But this paragraph destroys your thesis. Spall liners can be integral. From ballistic glass to the ARL study that explicitly demonstrates and describes internal spall liner layers, your assertion is incorrect.

Podboi is used as to describe inside lining, Nadboi is outside lining. The anti radiation liner itself is made out of composite materials.


QnA from 2019. Though I completely doubt these words.

Thats useful, if thats the case and anti radiation liners are modeled in game as Gaijin tells here, I will make reports regarding missing modeled anti radiation liner if we dont get spall liners revised. In case they will be removed I wont for obvious reasons. Why am I making these guesses? I doubt Gaijin will sit there doing nothing about it.

You’re being dishonest, the quote on the website says “They can also include acoustic and thermal insulation materials, either bonded onto the panels or integrated using a sandwich structure.”

They’re talking about combining thermal and insulation into the spall liner. Not into the metal armor.

Your naval ship argument is null because we’re not talking about ships, ships are large enough to have large bulkheads and metal separating compartments acting to catch spall. My photos above show the Abrams have a single thick backplate and there isn’t enough space to add shields.

my DTIC doc doesn’t contradict your source as my source is talking about production Abrams (document date is 1996), yours is talking about the XM1.

Additionally, permili heavily advertises their products, all permili spall liners are visible as panels which is missing on the Abrams. Also ballistic glass? What?

No. You are being dishonest. Here is the full paragraph that you removed the entire context from.:
‘PERMALI SPALL LINERS (roof, floor and walls) can be supplied in a range of E and S2 glass, phenolic or rubberised aramid, or UHMWPE materials, and to a range of thicknesses. They can also include acoustic and thermal insulation materials, either bonded onto the panels or integrated using a sandwich structure.’

The entire paragraph is about Permail spall liners. ‘Permali spall liners (roof, floor and walls) can be supplied in a range…THEY CAN ALSO INCLUDE ACOUSTIC AND THERMAL INSULATION MATERIALS, either BONDED ONTO THE PANELS or INTEGRATED USING A SANDWICH STRUCTURE.’

Where do you think insulation goes, my dude? It’s between walls.

The spall lining ARL document shows spall lining being incorporated into internal composite armor modules.

Between ballistic glass and the ARL documents talking about spall liners being embedded in integral armor arrays, you are the only one being dishonest here.

This only proves that the internal spall mitigation works. The guys lived. Your hanging kevlar blankets wouldn’t have stopped any of this.

Also from this report:

‘The U.S. Army Research Laboratory (ARL) and the University of Delaware (UD) have
developed an enabling technology to produce a polymer matrix composite-based integral armor
with improved multihit ballistic capability. Current applications for integral armor composites
include the Composite Armored Vehicle (CAV) technology demonstrator and Crusader
self-propelled howitzer platforms. Present integral armor manufacturing processes involve
adhesive bonding of a composite structure with ballistic armor tiles, spall shield, and nuisance
cover. ARL, UD, and the CAV/Crusader composite structure contractor, United Defense
Limited Partnership (UDLP), assessed through-thickness stitching to improve the multihit
capability and reduce manufacturing costs. The patent-pending co-injection resin-transfer
molding (CIRTM) process was used to produce a stitched, co-injected integral armor panel that
demonstrated improved multihit capability. The spall shield was fabricated with a phenolic resin
for fire, smoke, and toxicity protection, while the remainder of the integral armor (structural
composite resin encapsulating the tiles and the nuisance cover) was fabricated with an epoxy
resin for structural performance. Through-thickness stitching and CIRTM were used to enhance
the damage tolerance and to reduce the cost of the armor.’

Cope.

First things first, S2 glass is fibreglass not ballistic glass.

Copy and pasting the same quote I posted except bolding the letters doesn’t change the fact its talking about insulation and sound dampening and integrating that into the spall liner, not bonding the spall liner into the composite?

Yeah the guys lived, what? You think all crew died prior to the invention of spall liner? War Thunder has got you guys severely overestimating how powerful weak shape charges are. Edit: even strong shaped charges arent a crew death sentence, friendly fire incidents involving missiles like hellfires show crews can survive.

Your study doesnt apply to the abrams, a study was also conducted into making a composite hull bradley, that doesnt mean bradleys have composite hulls.

“cope” want a serious discussion? Go to GHPC discord server and “vehicle discussions” there are research members and crews that can talk to you about it. Because ive already spoken to them and other people about it. Of course you’ll only do this is you’re interested in learning

This has nothing to do with the M1. Its a paper on researching an experimental composite armor for vehicles that never went into production.

Even the second page says that this is not a official government doc and doesn’t represent the army.

Read the references and footnotes section. Plenty of references to the Abrams program. In this document, on the military website, from the ARMY RESEARCH LABORATORY, references many Army programs…and you claim its not an official government document? You are truly delusional.:

Look again, search ‘Abrams’ and see what pops up in the footnotes.

Speaking of being dishonest, how can you claim this…:
“The findings in this report are not to be construed as an official
Department of the Army position unless so designated by other
authorized documents.”

…some how means it is not an official document? It only said that it can’t be considered an official position, which it would be hard to do as a research paper and not a mission statement, order, or request.

…and who said otherwise?
This is the BALLISTIC GLASS you seem to have ignored:

I do find it amusing you guys completely ignored the two PDFs that explicitly refer to the XM-1 as having a spall liner.

The XM-1 was a prototype. Not the production M1s.

So let me get this straight, you’re arguing that the XM-1 being the prototype translates to the production model not incorporating the features that they insist be on the prototype?

I forgot about that link, sorry. But also wtf does this have to do with the abrams? This is anti spall film for glass? Glass… Metal is not glass, it doesnt shatter into a million pieces requiring a film holding it together

I mean M1E1 had extra steel welded to the hull to simulate increased hull weight. Afaik M1A1 uses the same hull armor as the M1. So for Gaijin its probably not good enough evidence

…which does not state that it is not an official document. It says the findings in the report aren’t an official position. You claimed it said that it wasn’t an official document. That is not what it says at all.

LOL! The cope and denial here! XD

It’s ballistic glass. That spall lining in between to hard and spalling layers stops it from shattering. Glass is well known for fragmenting into many dangerous pieces…unless it has a spall liner BETWEEN the hard layers. Keep up.
