Titanium grade? thickness?

[psycho_fling]

hi all

what grade and thickness should i look at for feather weight body armour? it has to obviosly not bend and be easily used for a lifter arm. also the previso armour 3mm aluminium suffered bably from big impacts (intentional of course), so with this armour i dont want the same problem

any help/

thanks alex

Titanium grade? thickness?

Depends on what capabilities on working the stuff you have.
Can you weld it? If yes, you want grade 2 or 3.
If no, you are limited to bolting or rivetting it to a chassis/frame. Then the higher grades are fun.

Weigth for weight, titanium is twice as heavy as ali, and 2/3ths the weight of steel/hardox.
That gives you, if you just replace the ali, without change in weight, 1.5mm Ti.

yeh i think i can get it weleded, but would 1.5mm be strong enogh? or were you just give an example?

The raptor Nebelwerfer used 1.2mm Ti as armor over 5mm HDPE. The Finnish raptor Projudju ripped the Ti appart as if it was butter.

I just gave a comparisation of what you would do by just replacing the ali.
So 1.5mm in a feather is ok-ish as long you dont go against spinners.

i was thinking, if the weight allows 3 or 4mm, will this stand up to spinners (if i ever face any)

Should do but then it depends on the spinner and on the circumstances of the hit. These things are always guess work.

4mm Ti is 15mm HDPE in weight. I know what I would use.

HDPE is a lot cheaper, easier to work with and strangely enough, more resilient to dents.

and if you have a friendly dutch roboteer available, repairable

Gary, Im Flemish.

But yes, with the right tools, HDPE is a nice material. It can be worked like wood, with the advantage of being weldable, bendable and virtualy unbreakable. Disadvantage, in some cases, is the fact it has a memory. It always will try to bend into the original shape.
This gave us nice surprises in the past. Like a wheel from TAN that went from crooked to straight after a few hours.

woops sorry mario

And lets not forget wood. 30 mm of oak or mahogany will stand up to any feather spinner Ive yet encountered.

absolutely. Wood is very underrated in robotwars.

is titanium easy to drill? to secure the pannels to the frame i thought about using bolts, but the way i want to do it wont let me put a nut on, and i tap the holes and do it that way? the frame is stainless steel box section

thanks alex

I have about 500 of them in Obsidian to prove it.
