Neil-NA Posted May 26, 2012 Share Posted May 26, 2012 Bit of a random one but does anyone know what the best thing to use to bond alloy to carbon? I am asking as i have a bike that has a carbon fibre back end but where the pivots are it is an alloy lug and the carbon and alloy are seperating slightly. Anyone any ideas.

sdistc Posted May 26, 2012 Share Posted May 26, 2012 Best bet would be to PM Swampy - he's done a few courses in carbon repair for the Airforce. Link to comment Share on other sites More sharing options...
ManwithSupra Posted May 26, 2012 Share Posted May 26, 2012 I use permabond ET500 for bonding carbon to Alloys/metal http://www.easycomposites.co.uk/products/structural-adhesives/rigid-5min-epoxy-adhesive.aspx Link to comment Share on other sites More sharing options...

ManwithSupra Posted May 26, 2012 Share Posted May 26, 2012 Looking at the spec of both of them, the DP-460 is the better product. Sheer point on the ET500 on steel is around 2000psi and the sheer point on DP-460 on the same material is between 2000 - 2400psi Link to comment Share on other sites More sharing options...
Neil-NA Posted May 26, 2012 Author Share Posted May 26, 2012 Ok thanks for the help, may look into the DP then. Link to comment Share on other sites More sharing options...

jay200bhp Posted May 30, 2012 Share Posted May 30, 2012 dp 460 isnt that strong and takes aaaages to cure fellas! you will need pink chassis glue ,otherwise known as 3m 9323 ba Link to comment Share on other sites More sharing options...
Neil-NA Posted May 30, 2012 Author Share Posted May 30, 2012 Ok so is this 3m 9323 ba going to be good enough for bonding carbon to aluminium its going to take quite a bit of abuse. Link to comment Share on other sites More sharing options...
Digsy Posted May 30, 2012 Share Posted May 30, 2012 I could ask at work tomorrow. We've got quite a lot of experience with structural bonding of carbon to aluminium. Link to comment Share on other sites More sharing options...
