Abstract
A method for producing a prepreg in which a reinforcing fiber base material is impregnated with a resin to produce a prepreg, wherein said method comprises: a step for preparing a first resin, which is the resin containing a filler, and a second resin, which is the resin not containing a filler; a step for arranging the second resin adjacent to the reinforcing fiber base material; a step for arranging the first resin adjacent to the reinforcing fiber base material and/or the second resin; and a step for impregnating the reinforcing fiber base material with the resin of the first resin and the second resin.
Claims4
A method for producing a prepreg in which the prepreg is produced by impregnating a reinforcing fiber preform with a resin, the method comprising:
- a step of preparing a first resin which is the resin containing a filler, and a second resin which is the resin without containing the filler;
- a step of disposing the second resin to be adjacent to the reinforcing fiber preform;
- a step of disposing the first resin to be adjacent to at least one of the reinforcing fiber preform and the second resin;
- and
- a step of impregnating the reinforcing fiber preform with the second resin, wherein
- in the step of disposing the first resin, the first resins are disposed on both sides of the reinforcing fiber preform and the second resin which are adjacent to each other, and
- one of the first resins disposed on both sides is a third resin which is the resin containing a first filler and a first dispersant, and the other of the first resins disposed on both sides is a fourth resin which is the resin containing a second filler and a second dispersant.
