A study on the improvement of environment resistance in epoxy composite materials due to variation of network structure for developing out door insulator

Epoxy resin specimens introducing the IPN method, were manufactured and then measured and compared with single network specimens as for environment resistance and tracking resistance. As a whole, ten kinds of specimens were manufactured by filler content. SEM and XRD were utilized in order to understand their structures and components. Also, Weather-O-Meter experiment and tracking resistance tests were executed to measure outdoor environment resistance. As a result of SEM and XRD tests, the variation of network structure was confirmed, and the environment resistance and tracking resistance appeared to improved.
