摘　　要：针对VARTM工艺对树脂基体的特殊要求,选用了一种粘度较低的不饱和聚酯树脂,对其工艺性能进行了系统的研究,分析了引发剂用量、温度对树脂体系的凝胶时间和流变学性能以及对浇铸体力学性能的影响。结果表明:树脂体系在40℃以下时,50 min内粘度低于300 mPa.s,加入0.5%与1%引发剂所得树脂浇铸体的力学性能差别不大。In view of the special requirements of vacuum assisted resin transfer molding（VARTM） process for the resin matrix,an unsaturated polyester resin with low viscosity was selected,and the processing property of the resin was studied systematically.The effects of initiator content,temperature on the gel time and rheological properties of the resin and the mechanical properties of the casting matrix were analyzed.The results show that the viscosity of the resin is lower than 300 mPa·s at 40 ℃ within 50 minutes.The mechanical properties of the casting matrix have little difference when the initiator content is 0.5% and 1.0%,respectively.
