Glue for alloy to spaceframe ?

[Billzilla]

I'm after suggestions for the strongest farking glue to stick the new alloy panels to the floor and sides of the racing car.
They'll be riveted as well, but I want the glue to be very good, expecially on the floor as it gets a very hard time.

you don't want something that is too rigid, as it will crack.. dunno how hard epoxy gets over time, but it may not stand up to the flexing perhaps?

you also don't want anything acidic.

what do bonded panel car makers use? a polyurethane of sorts?

Bill: one of the Godiva articles goes into depth about bonding honeycomb panels to a frame - PM Nero on PF if you dont have the magazine.

[Billzilla]

Thanks, am talking to Nero as I type this.

umm Bill this might sound a tad silly.. but you pilot big arse jumbos for Qantas yeah.. why not go ask one of the reputable senior qantas service personnel what they do with exterior panelling on the aircraft if a rivet or two pops loose?

Nah I'm not a Qantas poofta, I'm a different poofta.
I'll quiz some aviation mates of mine as well.

Hi Bill,

On our Fsae car last year we did exactly this, stresses aluminium panel between a spaceframe square section. It was rivited to some steel tabs welded to the spaceframe and bonded with an epoxy called 'Megapoxy' which was bloody strong stuff.
The guy who investigated the different types did his research fairly well.

At one stage we hit a large stone on the panel (it was a floortray) and it put a fair dent in the panel but didn't break the bond.

My brother in law (to be) is a builder and he uses some tough glue to glue stuff to cement. The cement chips off before the glue. Even though it is rigid I don't see it cracking. I can find out the name if you like.

BTW bit off topic but how hard is it to become a jumbo pilot and is it as cool as it sounds?

Thanks for that, I'll see what I can find.

See the floor on mine, it gets a very hard time ...

Ta.
Took me a couple of decades of work, and no.
Well, at least not for the chimapzee's I work for.

Bill I have used 8115 3M panel bonding adhesive here on a few projects to good effect.

It has a hi shear strength but not so good in peel .

Heres a link

Bill here is a link to Vivacity Engineering Pty Ltd
www.megapoxy.com
we use a lot of there products here on the airport,
the other stuff that comes to mind is Sikaflex
www.sika.com.au/index.htm
My little brother uses it to hold the side panels on the truck bodies he builds

[hamgatan]

....just dont use it to hold engine mounts together because it doesn't work. ask CoFF33!

[Bored?]

We have used some of the (loctite) hysol structural adhesives for bonding carbon parts. I can't remember the exact product though.

[TA-022]

Mega poxy is also used in compressed fibre cement facade sheetings on buildings.
Were talking 9mm concrete sheets nearly at 10-20 stories high


I can get for you through my work (CSR) at trade.


1 litre kit comes in two containers you mix together.

Trade $30.00

might be able to do better ...

[schnitzel]

Sikaflex is what we used to use on the formula ford, assume you are also going to plce washers under each rivet as this also helps strengthen join and slows fretting of your panel.

Yup, was going to suggest this also.
Major car manufacturers are starting to use this stuff to lower prices.

I've been told Sikaflex is what holden use to keep thier commodore firewalls in . It's funny even if it's not true.

[TooF]

i believe it is sikaflex.
