Fiber preforming is critical to RTM process in several aspects, such as thermal properties, preform dimension control, and tackifier compatibility with the matrix resin. These issues were investigated based on a medium-temperature tackifier (ES-T321) and its compatibility with the RTM matrix resin (epoxy 3266). ES-T321 can be applied in form of solution or powder. Its melting point is higher than the injection temperature of 3266, guaranteeing the dimensional stability of tackified preform. At the curing temperature of 3266, ES-T321 can be dissolved and reacted with the hardener of 3266. It is general compatible with processing conditions with 3266 without sacrificing the thermal properties.
