Titanium7 Posted July 2, 2015 Share Posted July 2, 2015 Have an inch long crack/split in a a rear pre-preg non glossy rear wing. I have some CF scrap pieces to strengthen from the back but need advice what resin/adhesive is best to use. The split/crack closes up nicely and would want to repair from the rear. Would epoxy resin (araldite) make a good bond or do I need to use polyester resin as in GRP manufacture? Link to comment Share on other sites More sharing options...
ECR Posted July 2, 2015 Share Posted July 2, 2015 Carbon Fibre pre preg is based on an epoxy resin normally so I see no reason why Araldite (epoxy resin) wouldn't suffice Link to comment Share on other sites More sharing options...
elie boone Posted July 2, 2015 Share Posted July 2, 2015 As the split coses up nicely i would use Sicaflex or any other make of glue, it's easier to use and gives better results. Link to comment Share on other sites More sharing options...
Barry Thompson Posted July 2, 2015 Share Posted July 2, 2015 I would use Hafixs , a German industrial superglue , along the crack. Then J B Weld (the normal slow setting twin tubes are the strongest) underneath , spread on wing and the strengthening strips . Both available on Internet , you will find it a 100 % mend for ever and easy to use. Araldite in my opinion is nothing like as strong . Both Hafixs ( keeps ages in fridge ) and J B weld I use to repair many things and never fail. My petrol tank got damaged and 10 years ago used JB to glue on aluminium plate. Perfect . Hafix far far better and far stronger than normal superglues . Hope helpful. Link to comment Share on other sites More sharing options...

solstice Posted July 10, 2015 Share Posted July 10, 2015 It might be too late but I have used plastex to good effect on bike fairings, might be worth taking a gander at the instructions even if you are using a different adhesive Link to comment Share on other sites More sharing options...
