Abstract

Research was conducted into the development of a lab scale resin transfer molding (RTM) system for use in composite materials research and university education. A reactive injection mold (RIM) was converted into an RTM mold to produce flat 11”x 11” sandwich panels for destructive mechanical test specimens. The complete RTM system configuration was designed for elevated resin infusion temperatures (>100 °C) for high viscosity (>400 cP at 25 °C) resins systems such as benzoxazine, and accommodate curing temperatures (>150 °C) per the requirements of commercially available benzoxazine resin. The RTM system was implemented for the manufacturing of benzoxazine/fiberglass sandwich panels and the process was optimized using 2^3 full factorial design of experiments, investigating the influence of injection temperature, total infusion time, and vacuum pressure on final part quality. The RTM process was qualified through the measurement of fiber/resin ratio and void content through burnoff testing in accordance with ASTM D3171.
