Stiffening...

Post by jayw » 12 May 2012

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:

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

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

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
