Hello,

I have recently made a couple of flat sandwich structure panels by resin infusion and after leaving it to set for three days I found that some of the panels' carbon fibre layers were still wet with epoxy and havent set yet. I have laid them out hoping they dry and set properly. I suspect its my fault since I may have used more resin than I needed. I would like to know whether the wet parts will eventually set and dry or not and if they do will it significantly affect the overall properties of the structure? Also, are there any troubleshooting methods I can take since I might not have enough time to make new parts before my project deadline?

Thank you

Did you mix the resin well? Because this could be a problem.. If it is too cold the resin will dry slower.. You can buy a infrared lamp (used for example for little animals or plants).. It works well for me and the parts are ready in 2-3 hours.. Maybe you can try but if you mixed bad the resin is a problem for the structure in my opinion..

I am confident the ratio was correct however I may have not mixed the epoxy and hardener very well despite leaving them to set and degas for about 10 minutes. The only heating I tried was heating with a heat gun for about 5 minutes and stopped. The carbon layers were getting very hot and the epoxy was turning from tacky to runny, I stopped as I wasnt confident if I am doing the right thing. Would you recommend I heat it for longer periods?
