摘要
对扭摆法进行改进后,测试了聚丙烯酸丁酯橡胶增韧环氧树脂固化的动态力学行为。研究了橡胶加入量和官能度对动态力学性能的影响,并对影响橡胶玻璃化转变温度移动的因素进行了讨论。
The torsional pendulum analysis (TPA) was modified so as to measure simplely. Dynamic mechanical properties of rubber toughening epoxy resin were measured by the modified TPA method. Results showed that the amount and functionality of rubber effected on the properties of this system.Shifting of glass transition temperature of the rubber was also discussed.
