Nanoflex

Ahh fair enough then Paul :)

Well then it would seem obvious to test this against 4mm pieces of other material then.
I realise this isnt a spinner test, but its a fairly simple (and repeatable) test that can be done. If you want to test it with a spinner, you need to find a way to anchor the material down or you wont get a sensible result.

Only suggested this as propping a piece of material up against a wall and driving into it seemed fairly simple, and I can be certian that Storm II will hit it at the same angle, at the same speed each time.

if it is of any help (never started a sentence with 4 two letter words before!)

I would be willing to attach each of said metal to my middleweight on different sides. If a spinner such as shredder wishes to then test each material in turn, they are welcome to. this is not a challenge to shredder, this is an offer of a machine (which can have ballast added to simulate 100kg if required) for specific tests once the main competion at enginuity is over. The 4 pieces of material would need to be delivered to me at least 8 days before the event to give me time to attach them, as I am a very busy bunny that week.

if Paul/Ed/Sam/Chris would like to discuss this option, the offer is there to catastrophically test these materials on a well built, solid chassis.

im up for that james, I for one want to see what this material is like!

Thank you all,

So how do we retain it for both tests? You cant drill it as its too hard, welding is out because of the laminations and adhesive.

Paul

pretty hard to use for a robot if u cant dril or weld it!

Im sure you can drill it. Suspect youd just have to take it very slowly with an appropriate bit, and use plenty of coolant as you go

Spark eroder?

Take it slow, flood it with coolant, and use a cobalt drill. If that doesnt do it (and Id be surprised) then water jet cutting is probably the way to go. I would guess its been heat treated, so laser-ing it, and I would guess spark eroding, wouldnt do it any favours.

Wed be more than happy to host that, quite possibly on the Friday night as we presently have that earmarked as a testing session anyway.

Drop us a line and keep us informed.

Chris, Nanoflex when supplied in its virgin state has a hardness something like Hardox 400. You can drill, cut, weld, bend it etc. When you have finished, you then bake it at 450 Deg C to take the hardness over 600. The test piece was specifically a laminate for the purposes of testing it as a bullet proof shield. It has already been baked and on top of that plasma treated making it very hard (how hard?) and tough. Nanoflex is not a carbon based steel like Hardox but more like a 304 stainless steel.

I will make a mild steel picture frame to go around it that could then be bolted or welded in position.

Thank you Sam, that is appreciated.

BTW, Sandvik are keen to see how their material performs in these tests.
