METHOD OF PRODUCING PREPREG

摘要

PURPOSE: A method for manufacturing a prepreg is provided to accelerate the impregnation inside a resin and to short the molding time by functioning as a heating site since the magnetic particles included in the resin passes through a hot plate of a permanent magnet form. CONSTITUTION: A method for manufacturing a prepreg comprises the steps of: (S10) preparing a resin containing magnetic particles; (S20) impregnating the resin containing magnetic particles into fibers and producing a prepreg; and (S30) magnetic-processing the prepreg. The step for preparing the resin containing magnetic particles is carried out by dispersing nano-sized metal particles to the resin.
