SAF Body Armour?

is it the spider web thingy? supposedly stronger than kelvar?Originally posted by bot_in_shop:Hey! If I remember correctly, didn't the Straits Times mention that Singapore was interested in Thailand-produced bulletproof vests that were supposed to offer the same level of protection as US-made Kelvar vests but with lower costs and weight? -
I don't know if i am mistaken, but i think i read somewhere that kevlar vests have limited life-spans due to UV affecting the material or some stuff like that. It would be good if someone familiar with this could say something about this. Vests have different grades of protection, and kevlar vests alone probably provide only protection up to knives and pistol bullets (i could be wrong, again). Even then, i understand that the possibility of sustaining internal injuries is quite high due to deformation of the kevlar to absorb the energy of the round.
As such, i believe that plates provide better protection in the military context where the speed of the projectiles are a lot faster. unfortunately, weight is a price u have to pay. So, the answer is to develop lighter plates. I think that's easier said than done, tho! -
think the tensile strength of spider-web is higher than steel per unit weight, but.... where u going to find so many spider to produce the tonnes of spider web that u'll need...Originally posted by foga:is it the spider web thingy? supposedly stronger than kelvar?
dun think we got the formula that our friendly neighbourhood spiderman uses to manufacture his webs....
as for the metal plates, i recall the show "black hawk down", where a guy remove the steel plate on his back saying that he won't get shot in the back cos he won't be running away from a fight...
so if we do tat too, we can reduce a bit of the weight but got to pray tat we dun get hit by "friendly fire"? -
Thai body armour uses good old slik, that is, slikworm slik which is also incredibly strong by the way to provide protection against ballastic threats.
No you probably will not sustain life threatening injuries from the deformation of your vest after it has stopped the bullet, this is because most vests are tested not to deform beyond a certain limit (1.5-2 inches) from the projectiles they are designed to stop to prevent internal blunt force trauma. You would get an angry bruise but life threatening injuries are unlikely.
Of course, you could avoid all this pain if you had a trauma plate insert, or better, a armour plate in your protection package.
As for spider silk though, it is still coming along. They are trying to get over the problems of farming spiders by using GM goats who produce the silk proteins in their milk, so there. -
Well, according to reports released, the Vest had suffered from at least 20-35% Ballistic Degradation since first use. The Policeman who suffered a fatal injury had only worn his Vest for 8 months, supposedly a Brand new one as well.Originally posted by dragonstar:If memory serves me right, the bullets penetrated at the EDGE of the vest - and the manufacturer claims that the fact that the vest is vulnerable there is properly documented.
It seems a bit specious of a claim to say that the EDGE Hit is the reason for the penetration. I believe that the Ballistic Degradation had much more to do with that.
And it wasn't some Low-Grade Kevlar too. It was Zylon, one of the newest Man-made fibres. When it is brand-new, it can stop High-Velocity 9mm rounds with nary a problem. And it is amazingly light and thin... However, its very vulnerable to UV and Water if i'm correct.
The nasty thing is that many Law Enforcement Agencies in US are now stuck with Brand new stocks of Zylon Armour... and their Suppliers are asking them to buy new upgrade packs. Why should the Customer pay extra for something that was supposed to work in the first place? -
You must be kidding yourself. The scene from Black Hawk Down was made in such a way so as teach a lesson to all soldiers never to dance with their own lives even for the sake of comfort. Also, never undersestimate your enemy or worse, belittle him. Sadly, this aspect of the film had to be interpreted rather than explicitly rationalised by the director or un-bias experts.Originally posted by Nothingie:think the tensile strength of spider-web is higher than steel per unit weight, but.... where u going to find so many spider to produce the tonnes of spider web that u'll need...

Well, there are still issues they are ironing out, especially with the Temperature and Heat tolerance of Spider Silk... Lots of Potential, it just has to be engineered the right way before it is marketed.Originally posted by SingaporeTyrannosaur:Thai body armour uses good old slik, that is, slikworm slik which is also incredibly strong by the way to provide protection against ballastic threats.

Last time paramilitary forces then to use MP5 as the standard. Sometimes with combat shotgun like SPAS12 as seen on pictures and news.
But nowadays they then to use Mk4/M16 5.56mm type weapons. Is it because of the introduction of Body Armour. If the bad guys have BA, they would be immune to 9mm rounds and shotgun pellets.
Also nowadays, optical sights seems to be standard issue already. -
Any of you guys here still train in MOG4 + body armor? I remembered 5 years back while I was still serving we had to don this and we were made to do some of the most horrendous PT ever
The FIBUA training in it was fun though -
yeap...most of them didnt bring along their NVG n extra water...Originally posted by panzerjager:You must be kidding yourself.

I just saw this and thought that it was worth posting.

I sincerely hope that our policemen don't wear any of this fella's products. Looks like Shit hits the Fan. -
BTW, that scene really happened in the real event, and the trooper killed was a real guy. Sgt. Casey Joyce was his name, and he had left his back plate out. The AK-47 round penetrated the back of his Ranger Body Armor, punctured his heart, and went straight through to be stopped, ironically, by his frontal plate, where his buddy found the bullet later.Originally posted by panzerjager:You must be kidding yourself.

Still anybody want to pass on body armor in war? -
The scene from the movie seemed to portray that the soldier was shot from the front - noticed the scene in which exit of the round was through the back instead. He froze for about 3 secs before slumpingOriginally posted by SingaporeTyrannosaur:BTW, that scene really happened in the real event, and the trooper killed was a real guy. Sgt.
