Resumen:
The dielectric behaviour of composite materials (epoxy resin barium titanate and epoxy CaCu3Ti4O12) was analysed as a function of ceramic amount. In both systems, components and tetrahidrofuran were mixed and pured into suitable moulds. Samples containing various amounts of ceramic filler were examined by thermal analysis. Dielectric measurements were performed from 20Hz to 1 MHz and 30ºC to 120ºC. It was found that the epoxy CaCu3Ti4O12 (CCTO) composites had higher permittivity than classic epoxy BaTiO3 composites.
