Frh076 2 Posted October 6, 2019 Can i bond two pieces of dry carbon fiber together by adding epoxy resin and a piece of carbon fiber cloth? Do i have to heat the dry epoxy, before i do it? Or will this not work? Any other ideas anyone? Share this post Link to post Share on other sites
Collin 1956 Posted October 6, 2019 Sandpaper the surface a bit and glue it together with 2k epoxy glue. It will last forever. I made 3mm brakediscs out of 1,5mm fiber sheets. Works like a charme. 1 Share this post Link to post Share on other sites

If you are looking to do that (which is effectively wet laying) it will need some compression to wet out all the fibres and a hardener to get the epoxy to go off. If there is space it's easier to make a lap joint by bonding another carbon plate over the split usibg the technique mentioned by @Collin Share this post Link to post Share on other sites
