|Abstrakt EN:||The epoxy resin curing is a chemical process that consists of several important steps within its curing time. These steps could be identified as gelation point, curing, vitrification and final solid state of the resin. These points of curing process are identifiable by standard electrical measurement methods but the use of unique test equipment is necessary. Therefore, new possibilities of detection these important points of curing process are to be searched. Based on that, it is necessary to analyze the curing process and to find its important curing points. During epoxy resin curing process some electrical parameters are changing. If a suitable sensor is placed in the epoxy resin during curing process then the above mentioned important points of curing process could be monitored and identified based on frequency analysis of signals from this sensors. This article deals with the evaluation process based on the spectral analysis of signals obtained from electrode structure sensor.|
