The study of thermal diffusivity, dielectric properties and fabrication of fabric composite materials such as carbon fiber-epoxy, glass fiber-epoxy and hybrid fiber-epoxy composite materials are identified and reported in this paper. Hand layup method was used for the samples preparation. Thermal diffusivity of these samples was measured using photoflash method. The thermal diffusivity values of these materials were compared with the thermal diffusivity of several materials including ceramics (SrTiO3). The results show that carbon and glass fibers have lowest thermal diffusivity values compared with other materials. Dielectric constant, dielectric loss and conductivity were measured at room temperature using impedance analyzer technique. It was found that although hybrid material has the same behavior of glass fiber but the value of the dielectric constant was significantly increased.
