Chassis/Armour to weight ratio

[maddox10]

The HPDE over a very resilient open frame isn't a bad idea , and there are some fine examples of that.
Unfortunatly, never seen one done in any degree of succes in heavyweight.

But don't worry about tear off. HDPE is sliced so easely that the opponent needs to hit a bolt to transfer a lot of force.

Of course, that's taking in account how many bolts of what size and what surface of washer you're suing to keep the HDPE to the frame. Holding 0.25m² 30mm HDPE with 4 M5 bolts won't cut the cheese.

Thanks for the link I've been following Ellis quite a bit.

I've built featherweight in the past when I lived in Oz never completed but for interest, started as a robot lawnmower lol. HDPE great for featherweight monocoque but heavyweight forces it's too soft as a chassis I changed to thin aluminium as the plastic was melting in Queensland sun!

No chance of that In Paisley lol!

Those materials are great in a featherweight but too soft for heavyweight with robots like carbide melting face.

Plus Ellis has access to tools I simply don't have with loads of experience and funds.

Hardox obviously is the material of choice I just fancy something different.

Going from Queensland sun to Paisley must have been a shock to the system
Suppose at least you're just down the road from the Robot Wars studio!

So I heard and my cousin was the arena MC.
