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?

Good thinking. Why not Wet-lay up and vacuumbagging it? you'll get some lightweight parts, well bonded together and so on...
