I'm trying to cover the inside of a 10mm carbon fiber tube with inner diameter of 8mm in thin layer of high temp food safe epoxy resin. The inner aperture is very important to me (precision I'm looking for is up to hundreds of mm). I achieve needed inner diameter by drilling with precise drill bits. The tube is approximately 50mm in length. My questions are: 1. Can I somehow spay the epoxy inside or do I have to apply it by hand? If applied by hand, what would be the best tool to use? 2. Would 3k rolled carbon fiber tube absorb the thin layer of epoxy resin and leave the inner aperture the same? Or do I have to polish it somehow (drill again?) after I apply it? Here is the resin I'm intending to use: https://www.atomadhesives.com/FDA-Grade-Food-Medical-Epoxy-Adhesives/AA-BOND-FDA8-FDA-Grade-Epoxy-Adhesive-Medical-Food I would appreciate your input! Thanks a lot in advance. Tags carbon fiber epoxy resin food safe high temp tube Edited 9 Years Ago by valzine

Very labour wasteful though. In all honesty, I don't think it would take a hell of a lot of resin to fill a tube of the pictured size. Probably 20ml or so, if that. Hanaldo, thanks a ton for your reply. What if I just use some kind of a foam applicator and paint it inside with a thick layer? Then drill to size? Would it work or the resin would just deform while being cured? Thanks!
