Abstract The composite materials for talcum powder coating was produced using the glass fiber bulk yarn fabric as the base material, E44 epoxy resin as adhesive, low molecular weight polyamide 650 as curing agent and talcum powder with low cost and small density as the absorbing material. The influences of content and coating thickness of talcum powder on the dielectric constant and conductivity were mainly investigated. The results showed that the prepared composite materials with the talcum powder coating have good dielectric properties. At the frequency range of the study, both the content and the coating thickness of talcum powder have major influences on real and imaginary parts of dielectric constant, loss tangent value, and real and imaginary parts of the electrical conductivity of the produced composites.

Key words： coating composite material dielectric constant electrical conductivity talcum powder glass fiber
