FridgeFreezer Posted March 1, 2009 Share Posted March 1, 2009 Depending how structural you're talking, Sikaflex does for most things. Quote Link to comment Share on other sites More sharing options...

smo Posted March 1, 2009 Share Posted March 1, 2009 Epoxy resin works providing you key the surface etc first - all depends on the use and how structural it is. Quote Link to comment Share on other sites More sharing options...

will_warne Posted March 5, 2009 Share Posted March 5, 2009 If you bond it's always good practice to add a rivet or 2 into the joint - it stops the joint peeling.... As Lotus has proved it is a very good way of creating a structural joint. Some of the abuse these little cars get is huge and there have been no issues with joint failures even the early cars have been around for over 12 years and some have done a pretty high mileage (and few Elises have easy miles ) Quote Link to comment Share on other sites More sharing options...
topsecret4x4 Posted March 5, 2009 Share Posted March 5, 2009 and having seen some crashed examples. bonding works as the joint was perfect it just tares the aluminium. Quote Link to comment Share on other sites More sharing options...
pongo Posted March 6, 2009 Share Posted March 6, 2009 If you know anyone in the aviation world, EC9323 is a structural adhesive used to bond aircraft structures. Ideally the areas to be bonded would be anodized first. Probably OTT for what you are after though? Quote Link to comment Share on other sites More sharing options...

secondjeremy Posted March 7, 2009 Share Posted March 7, 2009 I think the Lotus uses an epoxy adhesive and NO rivets for the chassis - seem to remember the chassis was made in Scandinavia and the adhesive was cured by careful heat. I don't know if they still do it this way. Quote Link to comment Share on other sites More sharing options...
HoggyN Posted March 7, 2009 Share Posted March 7, 2009 We've had the modern ally Jags and GT40s at work. Lots of rivets holding them together. Quote Link to comment Share on other sites More sharing options...

I would think NMNs dries quite hard and would not retain the degree of flexibility required in an automotive application. It's also not that heat tolerant and a Land Rover body can get very hot in the sun. Sikaflex/Tiger seal is the way to go. Quote Link to comment Share on other sites More sharing options...
Giles tout terrain Posted March 8, 2009 Share Posted March 8, 2009 Lotus Chassis's were made of extrusions of ali and were bolted and bonded with aircraft grade structral adhesive, I used to repair them all the time. Hutton sell a very good Metal Adhesive which is a 2 pack as Well as 3M do, there has been extensive testing at Thatcham on Crashing vehicles that have been repaired with bonded panels rather than welded. I may be wrong but i don't recall seeing anywhere where they say this is a safe method. But then that would be car structral panels/Safety cell, not a old 90!!

will_warne Posted March 8, 2009 Share Posted March 8, 2009 Will - what do Lotus use for the actual bond in addition to the rivets?? In this sort of joint the rivets are not structural - they only stop peel. I can't remember whether Lotus actually use rivets on all the joints but some have them and it's a standard practice. I would certainly do it for the reassusrance / longevity especially as a DIY joint won't be to the same standard as the sort of thing they do. As far as the glue goes this should cover it...
