Reviving an old thread. I am in the process of building a similar part. Here in the states we have easy access to epoxy infusion resins of about 325f max ratings and hand lay resins of 450f. Obviously I prefer infusion. The chamber shown by the OP incorporates a water injection system to keep the temps near 225f. I plan to build the chamber in 2 halves, bond them together, trim, then heat shrink or bag a couple braided sleeves over the exterior. Would anyone recommend a high temp coating for the inside of the chamber halves to apply before bonding and post cure? Would a thicker part with the infused 325f resin be comparable to a thinner, standard bagged 450f resin part due to less resin content and voids?
I had made a chamber similar to the power factor pipe few years ago using ADTECH high temperature resin. I forget the number of the resin but could prolly look back and find the number. Worked great
Thanks BSR. Exactly where I’m headed with my project. If you frequent the x-h2o.com site you may have seen the full carbon ski I made last year. I used adtech 820 with great results. Problem is my hull is so short that the powerfactor chamber is literally wedged in place. My plug is an alteration of the inner chamber to allow for some wiggle room in the ski. I will definitely check out the adtech high temp resin.
