摘要
采用锥板流变仪对LT-01A低温固化环氧树脂体系的流变行为进行了研究,以Arrhenius 1级反应流变模型为基础分别建立了等温和动态固化条件下的流变特性方程,并模拟实际固化工艺的温度历程对所建立的流变特性方程进行了验证,结果表明所获取的流变特性方程可准确地反映实际固化工艺过程中树脂体系的流变行为。
The chemorheology of low temperature curing LT-01A epoxy resin system was investigated using a cone-and-plate rheometer. The chemorheological equations under both isothermal and dynamic curing conditions were established respectively based on Arrhenius 1st order model. By following the temperature procedure of the cure cycle of the resin system, the validity of the chemorheological equations obtained was verified. Results showed that the chemorheological equations obtained could describe the chemorheologica...
