The composite composed of glass fabric and BMI resin was fabricated using resin transfer molding(RTM) process. it will be used as a supporting plate of transformer coil for high speed train. To develop a RTM process, permeability of preform was measured and resin properties like a viscosity and gellation time were checked. A resin pre-heating system and a mold system were also designed and developed. Using a vacuum-assisted RTM process, the composite supporting plate was successfully fabricated.
