초록

Characteristics of tree propagation and fractal dimension in DGEBA/MDA/GN system were investigated. In the GN contents of 0 and 5 phr, tree was not produced. In the GN content of 10 phr, a reversed sigmoidal behaviour was found but in those of 15 and 20 phr, linear behaviors were found. All electrical trees possessed fractal characteristics. Fractal dimensions of epoxy resin system were almost constant with the variation of observation angles. Since dielectric breakdown occurred earlier in the GN content of 20 phr, fractal characteristics of modified epoxy resin system in a particular term couldnt be investigated.
