PURPOSE:To obtain a reinforced body having high strength at the specific direc tion by dispersing ceramic fiber having electric insulating property into dispers ing liquid having electric insulating property and orientating the ceramic fiber to electric field direction by impressing DC high voltage in the unidirection, to form fiber proformed material. CONSTITUTION:The dispersing liquid 3, in which the ceramic fiber 2 are dis persed in a flask 1, is filled up. The flask 1 is formed according to number and shape of the staples and electrode plates 4 for forming electric field are arranged according to the direction to be reinforced and connected with the DC sorce 5. When the DC high voltage is impressed between the electrodes 4, the ceramic fiber 2 as dielectrics are polarized with the static electric field and supply the plus and minus charges at both end, to match and orientate the direction of electric line of force. Next, the dispersing liquid 3 is removed and frozen or hardened, to obtain the forming body composing of the orientated ceramic fiber. By using this forming body as the base material, the reinforced body having high strength at the specific direction in fiber reinforced plastic, metal ceramic, etc., is obtd. |
