I have a plastic item that has cracked, I used `plastic weld` to glue the plastic, I suspect that will eventually fail so want to strengthen with a metal plate (stainless steel) the size of the patch is approx 6 x
4 CmsOne option is pop rivets but I dont have enough clearance so was thinking of using some sort of epoxy.
Anyone got thoughts on what would be a strong bond. There will be some small vertical pressure but not a lot.
Depending on the plastic it may be better to bond a thicker similar plastic using dichloromethane (methylene chloride)if it is a plastic that it is a solvent for.
Its not the greatest bond but car body filler or chemical metal (tow part polyetser resins with filler) will bond to roughened metal well and roughened plastic a bit. That plastic looks like it is NOT an olefin (polythene etc.) which is good news.
Bad idea. A crack may well appear in plastic at the edge of the metal. Supposing it sticks.(Stress concentration) You need another bit of plastic with the edges tapered down. An a suitable solvent glue for that plastic.
pop rivets are the worst thing you could use on plastic.

Is there an echo in here?
A mate of mine was raving about Screwfix Nemesis the other day (it's a sort of aerosol "EvoStik", so not a gap filler). I have used it to stick flexible (EPDM?) foam to polypropylene.
