Caught in a flash fire - does a vest still work?

Filed under: Body Armor — Administrator @ 11:51 am

Another good example of our not-so-scientific approach to testing but hey, how many times are you going to face controlled environment like in a lab out there? Exactly, and that’s why we come up with these scenarios, because people come to us asking questions pertinent to real life. Like: “How well does your vests do against flash fires?”

We do not only believe in our stuff, we go out and find out. And you know how much fun it is actually, so of course we tend to go a bit overboard, but at least then we know where we stand. So we started burning our ballistic panels, first for 30 seconds, then for a full minute, and then shot them multiple times. Hmm, interesting.

Test 1. First we burned the armor panel for 30 seconds in gasoline fire.

Test Two

Then we shot the vest three times with MP-5, 9 mm FMJ at 1 443.5 fps (440 m/s), which correspondes to level NIJ-IIIA.

Test One Results

Results of Test 1: All shots were stopped and trauma in each shot was less than 0.98 inch (25 mm).

Test 2. We burned the panel full 60 seconds in gasoline fire. Well, this is not exactly a flash fire anymore, and anybody exposed to flames that long would not need to worry about his or hers vest anymore. However, we want to see how far can we go.

Test One

Then we shot it again two times with MP-5, 9 mm FMJ.

Test Two Results

Results of Test 2: Both shots were stopped and trauma was still less than 0.98 inch.

In conclusion, the C.P.E vests containing Dyneema do not loose their protective properties even after being exposed to open fire for extended period of time. Now I think that’s very good to know, particularly if you need to travel in a vehicle across hostile territory.

A day at the range

Filed under: Body Armor — Administrator @ 1:00 pm

Went to the range the other day to see how well our insert plates stand up against HK MP-7 PDW, or Personal Defense Weapon. The PDWs are intended, as name implies, to be a defensive sidearms for troops, vehicle crews and other military personnel who previously were issued pistols or in some cases submachine guns, but proliferation of body armour in recent years made the weapons ineffective. But of course, these beauties have many more potential applications besides that.

MP-7 is 4.6×30mm, rate of fire is 950 rounds per minute, and it has effective range of 200 meters.

The tool of the trade

The 4.6×30mm ammunition is loaded with spitzer-pointed, all-steel bullet with brass jacket. Bullet is 25 grains (1.6 gramm) and the muzzle velocity is about 2400 fps (ca. 725 m/s). Manufacturer claims 100% penetration of the CRISAT body armour (1.6mm of Titanium plus 20 layers of Kevlar) at the distance of 200 meters. Well, against soft body armor, yes, this baby will penetrate. But what about hard insert plate at NIJ-III level?

Lock and load, ready to rock ‘n roll. MP-7 is really nice weapon to work with. During my day MP-5 was the tool of the trade to have but if I got in active today, I think I’d choose MP-7.

Mp-7

The results were pretty nice. Actually, they were excellent because if I had been wearing that vest with insert plate, I would still be here to tell the story. Too bad, some of you may say, but hey…

The results

No penetrations! That makes me feel so good, you know. I am selling these plates and vests to cops and operators who depend their lives on them. ‘Nuff said.
