Body armour - what load of rot!

Www.re-zro.com

RE ZRO’s products are made from a single polymer which means they're extremely easy to recycle. This means that come the end of the product lifecycle, the armour can simply and easily be recycled.

RE ZRO’s Supermolecule Energy Absorption System protects the end user through the fracture of the molecular bonds under impact, releasing energy through heat and sound, a material behaviour known as shear-thinning.

The Supermolecules then recombine immediately after impact, REsetting to ZRO. RE ZRO’s products also benefit from patent-pending impact structures that further enhance the material performance to ensure impressive impact protection in a thin, flexible, and highly breathable protector.

Shear-thinning is a behaviour of Non-Newtonian fluids which serve as the basis for RE ZRO’s materials. This means that upon impact the material's viscosity decreases (softens) to absorb the impact force ensuring maximum protection in RE ZRO’s thin and lightweight armour.

If RE ZRO products end up in landfill the TOTO-TOA® technology enables bacteria and microbes to colonise the plastic and feast on the carbon structures of the products, breaking them down fully into biomass and biogas, biodegrading within 3-5 years.

In order to start the biodegradation process the RE ZRO parts must be in an oxygen-depleted, microbe-rich environment such as landfill so you can rest assured that whilst the armour is in your garment, it is doing its job and keeping you protected.

Interesting idea... said to be 'undergoing CE testing'... but I can't find anything about the new company proposing to make them.

Our entire product range is certified to EN-1621.

But have they had them type examined as PPE, the standard isn't the whole process / story?

A distinction lost on most people, including me

The interview they did just a few days ago said it was being assessed... got a link?

"Currently in testing for CE levels one and two, the purple armour is known as RE ZRO and is claimed to be capable of completely biodegrading in three to five years, should it find itself in landfill."

That was MCN on Friday last week.

Shear thinning? That takes me back a while. (Course component was rheology and our lecturer was an Aussie so I 'hear' all the terms with an Aussie twang ).

Common examples: tomato ketchup (fittingly!), cream and household paint.

I suspect this is actually a Bingham plastic ie thins under shear after a specific limit is reached.

Interesting though. Intuitively you might think you want something soft and flexible to wear that hardens on impact but, obvs, then the armour would just transfer the impact, not absorb it. I did ponder, in an idle moment, whether a suit could contain beads of material at impact points - a bit like a bean bag but in a tough but flexible container.

IIRC used in Ruroc helmets

I had wondered about two layers:
Outer hardens to spread load
Inner softens to absorb

Gravity would not be your friend. Does this suit make my arse look big? No, it's either the chocolate cake beer pie and chips, or CountSteer's SupaDupaBeads have migrated

I was thinking of shoulders, knees and elbows and lightweight beads rather than bums and ball bearings.

Mind you, if a sandbag can stop a bullet.....

Ta, that didn't come up at all when I searched for it a few days ago.
