为研究固化温度和固化速率对光纤线包固化均匀性的影响,基于复合材料细观力学理论对线包固化过程进行了仿真研究。结果表明,固化过程由外及内,内外固化度最大差值出现在固化速率最快阶段;升高固化温度可以缩短固化时间,但会使得最大温度差值和最大固化度差值增大,从而导致线包固化均匀性变差;升温速率对固化均匀性的影响不显著。研究结果对固化工艺参数的设计提供参考。

In order to study the effect of curing temperature and heating rate on the uniformity of fiber optic package curing, this paper simulates the process of wire pack curing based on the theory of composite material mesoscopic mechanics. The results show that the curing process is from the outside to inside, and the increase of curing temperature can shorten the curing time, but it will increase the maximum temperature difference and maximum curing degree difference, which will lead to the difference of line pack curing uniformity, and the effect of heating rate on curing uniformity is not significant. The results provide reference for the design of curing process parameters.
