Characteristics of composite materials of epoxy resin and inorganic particle can be improved thanks to alignment of the particle chains. These chains are formed by applying an electric field during curing process. It is important to form the chains so as to obtain the stable quality. Forming the chains is affected by various factors such as gap length between electrodes, applied electric field and specification of particle including size, gravity, permittivity and content. Therefore, the authors established a simulation method of the particles movement in a liquid under AC electric field to elucidate the effects of these parameters on the formation of the chains. This paper reveals the effects of the parameters on particles movement, and comparison of particles movement between the experiment and the simulation.
