27-43 STUDIUL EXPERIMENTAL AL COMPORTAMENTULUI DIELECTRIC AL DIGLICIDIL ETER DE BISFENOL ”A” ÎNCĂRCAT


EXPERIMENTAL STUDY OF THE DIELECTRIC
BEHAVIOR OF DIGLYCIDYL ETHER
OF BISPHENOL ”A” CHARGED
Subject reinforced composite materials are extensively investigated in recent years. This study is deepened to improve the structural and dielectric characteristics of diglycidyl ether of bisphenol A (DEGBE). Dielectric properties were analysed for each batch of material. Microcompozite epoxy samples with good dispersion of nano – particles laden epoxy matrix was prepared and experienced for the dielectric constant (C) , resistance (R ) and impedance (Z) frequency (1kHz, 10kHz) . Measurements were made using a dielectric spectoscropia plateau temperature range of between 20-80 °C . The better dielectric properties of the material corresponding to the nano – fillers in a concentration of 30 % .
