The performance of T700/3228 prepreg was studied by differential scanning calorimetry（DSC）， infrared spectroscopic，rheometer and mechanical properties testing.The result shows that the initial curing temperature and peak curing temperature are 67.9 ℃ and 89.5 ℃，respectively. The viscosity for 3228 resin at 60 ℃ is between 20 to 30 Pa·s and maintains more than 2 h.When temperature is above 65 ℃，the rapid curing characteristics is showed. The composite with low porosity and good mechanical properties have been prepared by adopt 60 ℃ procuring 1 h，80 ℃ curing 3 h as molding process plan.
