Richard, it was a point force of approx 25mm diameter. I will try it again with a sharp object but I need to find something hard enough first. Any ideas?

High speed steel cutting tip?

Grind up a suitable point on a Cobalt Tool Blank if you have one to hand.

Or use a centre punch.

a ball bearing should do better.

Well, I just tried a pointed bit from a pneumatic chisel which I have used for breaking up concrete. Not too sure of the final force but must have been close to the 8 tonnes again but I bottled out. The chisel bit became blunted, started to compress and deform over to one side. The Nanoflex however, was virtually untouched, it had a mark on it of an estimated few thou deep and no deformation.

Okay, what else shall I throw at it?

Nice material!!

Doesnt sound like you can try much more Paul.

Paul, bring it along to an event and Ill drive a Storm II spike into it at full pelt ?

Now that would have been cool! What about the Feather Weight Smash this Saturday?

Ill bring it along on Saturday regardless but I doubt the feather arena will be the place to do it. I would like to try it out in a real life situation so if someone wants to take it away and try it at say Enginuity, thats fine by me as long Sam & co are prepared to allow it to happen. Maybe one of those nasty crushers would like to try their luck at it?

No, I wouldnt reccomend that test in the feather arena.

I would suggest that the results of a slow pressed force shouldnt be read into too deeply as to the performance of the material. Theres a big difference between 8 tonnes being gradually applied with a press, and being applied in an instant - the energy that the material has to dissipate to prevent breakdown is significantly higher in an impact test.

Paul, if you bring it along to Enginuity we could stand it up against the arena wall and I could reverse Storm II into it (spikes first) at full speed. If we could also get a sheet of 3mm Grade 5 Ti and a sheet of 3mm Steel and 3mm Hardox and do the same tests with them, wed have a good basis for comparison ?

Or is that all too scientific ?

Definatly not too scientific, but wasnt the piece 4 mm thick?

Im a bit more interested in spinner damage. Could one of them have a go please.

Ed, my tests was just to replicate those hydraulic crushers. This is why I want to conduct further tests on the material. I will not be at Enginuity but if you are okay to take the Nanoflex and try and break it, I would be most pleased!

A spinner test would be great but not practical with the test piece as there is no easy means of restraining it.

Yes the piece is a laminate of 3 pieces of 1.4mm, 4.2mm total.
