The curing reaction of CYD128/DMP- 30 system was characterized using gelatinization test and differential scanning calorimetry （DSC） analysis in this research, where the gelatinization time is 70min at 20℃. The mechanical properties and heat resistance of casting plastic were tested and results are as followed, flexural strength 156.7MPa, impact strength 15.0 kJ. m^-2, and glass transition temperature 96℃. The properties of continuous fiber reinforced CYD128/D,MP- 30 composites were studied, and the flexural strength of continuous glass fiber reinforced composites is 954.8MPa. The flexural strength of continuous carbon fiber reinforced matrix is 1057.4MPa.
