Hello, i make carbon fiber infusion piece, and i attached heat-wire to the backside, simply say i plan to make a personal heater using heat-wire as heating element and the carbon fiber piece as a radiant part. I attached picture to show how the part looks like I use normal epoxy resin and found out after i connect electricity and temperature rises up (Max. temperature at the front side of carbon fiber is 110 degree C and the one on the backside (where the heat-wire is) is max. 140 degree C) that my carbon fiber part is still in good condition though the surface is slightly soft when getting over 100 degree C, but the epoxy resin turn slightly brown. i.e. on the front shiny black carbon fiber surface, it become slight brown in some areas. what i want to know is that : 1) carbon fiber part resists high temperature, the carbon fiber looks the same black, i believe the epoxy resin still has its bonding ability within the carbon fiber, so what burn should be the pigment in the epoxy resin, any ideas? (when i first make it i used epoxy resin that can resist 50-70 degree C, i used it because i had it available, just first trying) I don't know, if you would make carbon part for car exhaust, what is the right epoxy resin people are using? 2) I now try to get higher temperature resistance epoxy resin. Meanwhile, I understand that after you get the carbon fiber part, post cure, it will resist high temperature and getting high strength, but i do wonder, will we treat the normal epoxy resin the same way we treat high temperature resistance epoxy resin, use it the same way - for infusion? (the new epoxy resin i will use is 220 degree C temp. resistance) I just happen to think that, do we need to prepare the high temperature resistance resin before putting into infusion process, i.e. pre-heat?...Does anybody ever try or can advise me on this? I know i can make infusion and look at it, but if there is the right practice to do before starting any process, i would like to try it, at least i wont burn much money here. I am welcome all advises, and feel free to share your ideas, Thank you in advance, Pu
