为了对树脂基复合材料在热压罐固化过程中进行实时监控,使操作人员能在生产过程中观察其固化过程,选取最佳加压点,为产品的质量监控创造条件,1980年开始,对树脂固化过程中的动态介电测试方法进行了探索,1985年研制了自动测量、自动显示、自动记录、自动控温控压的JCK-1动态介电测控仪。 1988年,在508所热压罐上,用我们研制的JD-1介电仪和LZ-300函数记录仪,测得了碳/648环氧树脂加3%BF_3·MEA的介电谱,见图1。图中,介电损耗为实线,电容为虚
In order to monitor the curing process of the resin-based composite in the autoclave in real time, the operator can observe the curing process in the production process, select the best pressurization point, and create conditions for the quality control of the product. Since 1980, Resin curing process of dynamic dielectric testing methods were explored in 1985 developed a automatic measurement, automatic display, automatic recording, automatic temperature control pressure JCK-1 dynamic dielectric controller. In 1988, the dielectric spectra of carbon / 648 epoxy resin plus 3% BF_3 · MEA were measured on 508 autoclave using our developed JD-1 dielectric and LZ-300 function logger, see figure 1. In the figure, the dielectric loss is solid line, the capacitance is virtual
