摘要: 本文采用数字式粘度仪对不同温度和促进剂含量下添加氢氧化铝(ATH)的不饱和聚酯树脂(UPR)的粘度进行测试,然后以获取的实验数据作为参数,对复合材料部件模型用RTM(Resin transfer molding)和VARTM(Vacuum assisted resintransfer molding)两种工艺进行模拟仿真。仿真结果表明,在相同的参数条件和灌注方案下,VARTM 工艺的填充时间小于等于RTM 工艺的填充时间。当注口大于出口时,VARTM 和RTM 的填充时间基本相同; 当注口小于出口时,VARTM 工艺的填充时间要少于RTM 工艺的填充时间。

Abstract: This paper tested viscosity of the unsaturated polyester resin (UPR) adding aluminum hydroxide (ATH) in different temperatures and the content of accelerator by digital viscosity instrument, and simulated VARTM(resin transfer molding) and RTM(vacuum assisted resin transfer molding) process using a composite part. The simulation results show that: the filling time of VARTM process is not longer than RTM process, and when the inlet is larger than the outlet, the filling time of VARTM process is almost equal to RTM process, when the inlet is smaller than the outlet, the filling time of VARTM Process is less than RTM's.

Key words: ATH, UPR, orthogonal experiment, RTM, VARTM, PAM-RTM, simulation
