Stiffening...

Yello peeps!

Imagine you have a thin-wall steel tube and you want strengthen it by filling it with some kind of pourable liquid. Something stong and chemically hardening (due to the lack of air).

I'm thinking along the lines of epoxy but anyone got any ideas of anything out there that's stronger? I'd need about 3kg.

Links to products would be helpful. Cheers!

I take it that this tube is not a regular tube shape? If it was then, internally sleeving it with a stronger pipe eg galvanised gas pipe (if you can still get it) or similar would be more effective. Epoxy would probably be strong enough to fill any small gap between the tubes.

GRP compounds from Strand Glass (Brentford) would probably be better if it's an irregular shape and cannot be internally sleeved. They seem to have been taken over by Scott Bader whose nearest location to you will be Plymouth:

PS: that sea off the coast of Sweden on their map looks like an image of Jimi Hendrix playing the guitar in the spotlight! (with guitar shadow) :)

Yes it's a very irregular shape and not suitable for anything but a pourable substance...

Not seing Hendrix, but i am getting Willow the Wisp... :wink:

Slight lack of tensile strength :lol:

Believe it or not, the concrete spring shown here has a strength of over 200 N/mm2. David Bennett, a consultant on architectural concrete, predicts concrete will overtake plastics and ceramics, with applications such as thin staircases and even telephones

Sand. I got plenty of it here. Been in the desert all day down at Azzawiyra. Bloody place is a right mess fucking bomb holes everywhere including the road. Plus my driver doing 140kph and swerving round them....interesting [pray]
Weather has been excellent no wind sunny all day and a steady 30 degrees.
I believe it's a bit windy in UK?
Keep hearing gunfire about 3 am, probably some night shift twat having a laugh

I'm saying nothing!

Is weight an issue? Few more details would be good, like size, wall thickness and what the hell it is for?

Too many details could be dangerous to ones health... :wink:

But, weight isn't an issue. Wall thickness is 1mm and the cavity it is to fill is mostly 3 or 4cm3 with a bulk at each end around 10cm x 10cm (imagine a barbell shape), however it is an irregular shape throughout.

The purpose is to help stop the "bar" of the imaginary barbell bending, so tensile strength is the main concern. It cannot be sleeved or reinforced with metal and the only real option is a pourable setting liquid reinforcement. That's all i'm after, maximum reinforcement, not a miracle :D
