The application for my carbon fiber designed parts requires a high temp resin as they will live around high revving engines. I know the high temp resin available here has approx a 500 viscosity rating, and as I can tell a vis of 225 is required to use in the infusion method. What would I need to do to remedy this issue. I need to use the infusion method to create these parts for a few reasons. 1. A pre-preg is not always an option because of my use of custom designed, colored and sizes of fabrics. 2. Lay-up method results in parts lacking consistency in quality. 3. Infusion has become the method I've found reduces production time. If the high temp resin is pre-heated or warmed would that lower the viscosity enough to flow in infusion? What can I do to make parts with infusion that can comfortably live at a minimum temp of 110C?

Now I haven't tried this and we are dealing with chemistry here so be careful if you try what I am about to suggest. I was talking to a chemist that worked for an epoxy manufacturer. He said that one of his customers that made honeycomb carbon fiber plate used up to 10 % pure alcohol to reduce the viscosity of their infusion resin.It speeded flow and eliminated pinholes.
It might be worth an experiment to see.
Hope this helps.
