Abstract
Polymer matrix composites were fabricated using a modified injection molding technique in which nano-sized silicon oxides, titanium oxides, and aluminium oxides were contained. Nano-sized oxides were uniformly distributed in the composites produced by modified injection molding combining vacuum degassing and curing at a moderate temperature. The thermal decomposition and evaporation of the epoxy resin matrix depended on the composition of the composites. The relative permittivity of the nano-sized silicon carbide-epoxy composites increased from 5.16 to 5.37 by adding 2.0 wt % titanium oxide. The addition of titanium oxide of up to 2.0 wt % had little influence on the permittivity. The addition of 2.0 wt % of titanium oxide to epoxy resin showed the maximum thermal properties. Both the thermal conductivity and thermal diffusivity of the silicon oxide-epoxy composites tended to increase with titanium oxide content. The maximum thermal conductivity was observed in the composites with 2.0 wt % titanium oxide.
