aluminium support

[cagey]

have an aluminium support that is at the stage of corrosion where it still has its form but is friable and fragile, It also appears porous,a bit like pumice, could I soak it in resin of one form to maintain its integrity. the support is not sujected to any loads it purely holds a couple of light components out of harms way.
If possible could you please advise what type of resin to use.
Thanks
Keith

I'm not sure that resin alone is OK to stand compressive forces. You might need fibre, carbon or glass, to help. Any pic ?

Thanks Tim, Only compressive forces would be fasteners and these I could sleeve, I am just looking at this as an idea, to fabricate new would be too expensive, just need a guide as to what resin to use as viscosity will be critical
Thanks

It's difficult to "see" your problem w/o picture

A good source for information on using epoxy is found here http://www.westsystem.com/ss/use-guides/ and here http://www.westsystem.com/ss/how-to-use-demos/

You can adjust the properties of epoxy by using different fillers, microfibers act as reinforcement and is also used for thickening the mix.

Epoxy does not bond to soft plastic (packing tape, plastic bags and ice cream containers++), so one way to get the shape you need is to make a temporary mold (one time use) to help keep the epoxy in place while hardening.

Remember that epoxy need UV protection.
