It's supposed to be a semtex device for an undercar bomb, described as sophisticated, but it looks unbelievably crude and is that a match fuse? One of the strange things is that is suppose to be semtex dating from the late 80s early 90s but semtex has a shelf life, is it in fact something else home made? No polititics please (it's a hard left kremlin nutter trying to larp as the PIRA) just want the thoughs of people who known their stuff on explosives on the object itself.

What mind of fuse/detonator?
Is the fuse detonnator home made or commercial?
Is it old semtex or something home made or something else?
Surely that is far more semtex than is necessary to blow up a car?

>bomb, described as sophisticated
Do you understand that explosive device and the charge are not essentially the same definition and the former could be a modern sensor-triggered remote-detonated smart bomb with many layers of anti-disarming circuits and implements, while the latter could be a WWII era turd or just ANFO in a cookware, wired to the aforesaid bomb?

>described as sophisticated, but it looks unbelievably crude
This is just the explosive charge, it doesn't have to be sophisticated or pretty.
Tthe means of detonating it (where all the sophistication is) isn't shown.

>One of the strange things is that is suppose to be semtex dating from the late 80s early 90s but semtex has a shelf life, is it in fact something else home made?
Looks a hell of a lot like Semtex to me. It's a BIG charge too.
There are two types of plastic explosives in common use, one is C4, the other is Semtex.
C4 is almost always white, Semtex isn't. That stuff ranges from beige to orange.
Shelf life doesn't mean it instantly stops working when the date expires.
It just means the manufacturer doesn't grantee that it'll still work as intended after the date expires.
Old expired explosives are still dangerous. Lots and lots of bombs and mines from WWII are still functional.

I can't say who planted this device or why, but it's most likely made from some of the old Semtex that Ghadaffi provided to the IRA back during the troubles.
That doesn't mean the IRA were directly involved in this particular incident.

That's just a lump of some bullshit, I'm not even going to answer the rest. A good thread (probably) died for this shit
>is that a match fuse
You're gonna have to point it anon, or rather, just go away

A major advantage of plastic explosives is that they do not require containment in a sturdy casing for detonation.
>>
>>65363675
That's true for real all high explosives.
For example, a bare block of solid TNT will have the same detonation velocity as TNT contained within an artillery shell.
Western-made "demo-blocks" are often cast TNT poured into plastic boxes or flimsy sheet metal containers to protect the explosives from the elements, but the packaging has no effect on the explosive properties of the TNT.
A lot of cheaper TNT Demo-blocks are just solid bricks of TNT packaged in waxed paper or cardboard. (pic rel)

However, "fluffy" or "loose" low density powdered explosives can benefit from containment.
But the same effect can be gained by just compressing these products into solid pellets, pucks, blocks, which don't require any containment to achieve proper detonation velocity.

That even applies to the nitrocellulose that makes up the bulk of modern smokeless gunpowder.
A solid block of nitrocellulose set off with a blasting cap will undergo proper full-velocity detonation without needing any sort of containment.
Such blocks of nitrocellulose were widely used as military demolition charges way back in WWI.

>inb4 I get put on every watchlist in existence for just mentioning this basic common knowledge shit here.

That looks like a fruit pudding to me.

It looks like the basic M700 Bickford safety fuse, which is still used pretty much everywhere there is mining as they're cheap, simple and the detonator is very simple with just a regular metal tube, aa primmer charge that goes into a base charge which sets off the explosive. I mean there's all sorts of basic detonator systems ranging from electric, shock tube, wireless and so on which are much the same type of thing in the end.
Semtex has been around a long time, comes in about 3-4 different flavours with a variety of compound mixtures, but yep. Its just a plastic explosive made of various ratios off RDX and PETN, some binders too hold it all together and it goes bang. Reason it was 'popular' was they made it by the thousands of tonnes, its relatively hard to detect, powerful, easy to use and most importantly- they sold it practically to anyone and as much as you want.

Looks like Corsican cheese. There's a documentary about the explosive potential of those.

This could also explain what you are seeing as inconsistencies, they just didn't know what they are doing.
As to semtex having a shelf life, it doesn't just evaporate after a certain length of time. The device hasn't exploded, we don't know how "ripe" it is.

>>65363706
Wait so they literally just put gunpowder in a mold and then pressed it with a hydraulic press? I don’t know why but I always assumed there was some kind of detonation risk at high psi even if peak pressure was achieved slowly.

I was trying to make a chocolate chunk holiday bread you motherfucker and you've turned it into a terrorist plot! Just look at him manhandling me bread!

>>65363879
Nope. Shock has to be high velocity, thermal blah, stuff, potato.
Find a book for the math.

Is plastique the same thing?

>Is plastique the same thing?
That's just the French word for plastic, which in English is used for short for Plastic Explosive.
