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.
Claims7
A method for producing a prepreg in which a 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.
A method for producing a prepreg in which a prepreg is produced by impregnating a reinforcing fiber preform with a resin, the method comprising:
- a step of preparing a third resin which is the resin containing a first filler and a first dispersant, and a fourth resin which is the resin containing a second filler and a second dispersant;
- a step of disposing the third resin to be adjacent to the reinforcing fiber preform;
- a step of disposing the fourth resin to be adjacent to the reinforcing fiber preform on a side opposite to the third resin;
- and
- a step of impregnating the reinforcing fiber preform with the third resin.
