D3O material?

[kramdra]

Got some new running shoes today that contain this - first Ive heard of it. Seems like it might be good for bike armour/helmets.

Essentially it behaves like custard. On impact, it locks into a hard shape, but normally is flexible.


https://en.wikipedia.org/wiki/D3o
"In 2009, the UK Ministry of Defence awarded D30 Lab £100,000 to fit helmets in order to reduce the kinetic energy of a bullet or shrapnel on impact, because of its moldable properties."

Does not seem to be mentioned on BCF, done a search.

Is it any good?

(there are cheaper ones)


It might also be good as bike crash protection?

I do recall someone making a very expensive set of textiles lined with that stuff.

As to its efficacy, pass.

I think it is in furygan kit. It passes CE tests, so it probably works.

I have some d3o hip pads in my textile trousers, they weigh next to nothing and are soft and flexible and I barely know they are there. If I hit them with something hard, my knuckles for example, they feel and sound like hard plastic.

Was looking for some level two elbow, knee and shoulder pads but got a set of forcefield instead. Will likely replace the armour in my HG jacket with d3o if I find some suitable.

Full scientific test of D3O armour.

Sorta wish I'd had it for the knee armour in my crash recently, as I'm currently trying to heal up a jagged laceration where the Knox armour's hard shell dug well down into my flesh. The test above is a bit silly, as you'd generally only take one or two big knocks to one area. I do have it in my Furygan jacket as well, and in my bike jeans, where I barely notice it.

D3O has non-newtonian properties that are pretty good against high impact, but it would need to be incorporated with something else to give effective protection against injury caused by friction and sliding.

Meh, a sandwich can pass CE armour approval.

There a fer manufacturers shipping their kit with D30 now, Klim, Furygan and Hood to name a few. Its a bit like SAS-TEC armour, but alot thicker.

There was a report in the March/April ABR magazine about some dude (Dr John Lloyd) waffling on about how helmets are rubbish and inadequate. So hes inventing a helmet with a non-newtonian material in it to prevent brain damaged. Which to me sounds alot like D30 armour...

Chunks of foam wont stop broken bones. For what it's worth, I've crashed twice in gear that was fully CE armoured and still cabbaged myself. Wouldn't bother upgrading existing armour at a cost of £££, however I did swap the Knox back protector out of my old jacket into my new one as it had a very thin piece of foam.

Anyhow,

This stuff is a lot more comfortable than the D30. Would rather have the Quattrotempi, Held are using it in a lot of products at the moment.

I have it on the palm of my gloves. Fingers crossed I don't get to test it.

I've got d30 armour in my Richa jacket, haven't tested the crash properties but don't plan to either.

All i can say is that its a lot comfier than my old Knox back protector.
