Abstract
According to the present invention, a method for manufacturing a prepreg sheet includes steps of (A) forming a resin layer 61 on a surface of a supporter 3, (B) winding a reinforcing yarn 10 around the resin layer 61, and (C) embedding at least a part of the reinforcing yarn 10 in the resin layer 61. Preferably, in step (C), the surface of the supporter 3 is relatively moved towards the reinforcing yarn 10.
Claims20
A method for manufacturing a prepreg sheet, comprising steps of:
- (A) forming a resin layer on a surface of a supporter;
- (B) winding a reinforcing yarn around the resin layer;
- and
- (C) embedding at least a part of the reinforcing yarn in the resin layer.
1 more element
An apparatus for manufacturing a prepreg sheet, comprising:
- a supporter on which a resin layer is to be formed;
- a fiber holder for holding a reinforcing yarn to be wound around the resin layer;
- and
- a fiber embedding member for embedding at least a part of the reinforcing yarn in the resin layer by relatively moving a surface of the supporter towards the reinforcing yarn wound around the supporter.
1 more element
A prepreg sheet comprising:
- a first surface resin layer;
- a second surface resin layer;
- and
- a fiber bundle disposed between the first surface resin layer and the second surface resin layer;
- wherein the second surface resin layer contains more filler than the first surface resin layer.
