PROBLEM TO BE SOLVED: To provide a method for producing a preform which prevents the bridge of a reinforcing fiber substrate or a subsidiary material, maintains the thickness of the corner part to be a prescribed thickness, and prevents the occurrence of a resin-rich part or a void in the corner part when FRP having a corner part is molded, the preform produced by the method, and a method for producing the FRP. SOLUTION: In the method for producing the preform, when the preform for molding the FRP having the corner part formed by using the reinforcing fiber substrate is produced, throughout at least the corner part and its both side parts, with the subordinate material integrated with the reinforcing fiber substrate, the preform is shaped. The preform produced by the method and the method for the FRP using the preform produced by the method are disclosed. COPYRIGHT: (C)2009,JPO&INPIT |
