Abstract: The rheological properties and curing properties of the domestic epoxy resin were studied through the rheometer and differential scanning calorimetric apparatus. The injection process window was determined and the comprehensive performance was charactered through mechanics performance analysis. The microstructure of the domestic carbon fiber monofilament was charactered by SEM and the contact angle of the carbon fiber and epoxy was studied by the surface tension tester. Comparing with the overseas import carbon fiber and epoxy, the paper found the difference in performance of the RTM process.

Key words: epoxy, carbon fiber, RTM, processing property, curing property, mechanics performance
