Abstract
The present invention provides a fiber-reinforced composite material including a first fiber-reinforced sheet in which first prepregs including reinforcing fibers arranged in one direction and a first thermoplastic resin are woven to cross each other, a second fiber-reinforced sheet in which the first prepreg, and a second prepreg including reinforcing fibers arranged in one direction and a second thermoplastic resin are woven to cross each other, and a third fiber-reinforced sheet in which the second prepregs are woven to cross each other, wherein the second fiber-reinforced sheet is disposed between the first fiber-reinforced sheet and the third fiber-reinforced sheet.

A fiber-reinforced composite material, comprising
- a first fiber-reinforced sheet in which first prepregs including reinforcing fibers arranged in one direction and a first thermoplastic resin are woven to cross each other,
- a second fiber-reinforced sheet in which the first prepreg, and a second prepreg including reinforcing fibers arranged in one direction and a second thermoplastic resin are woven to cross each other, and
- a third fiber-reinforced sheet in which the second prepregs are woven to cross each other,
- wherein the second fiber-reinforced sheet is disposed between the first fiber-reinforced sheet and the third fiber-reinforced sheet, and
- the first thermoplastic resin of the first prepreg and the second thermoplastic resin of the second prepreg are different thermoplastic resins.
A method of manufacturing a fiber-reinforced composite material, comprising
- manufacturing first prepregs including reinforcing fibers arranged in one direction and a first thermoplastic resin,
- manufacturing second prepregs including reinforcing fibers arranged in one direction and a second thermoplastic resin,
- weaving the first prepregs to cross each other to manufacture a first fiber-reinforced sheet,
- weaving the first prepreg and the second prepreg to cross each other to manufacture a second fiber-reinforced sheet,
- weaving the second prepregs to cross each other to manufacture a third fiber-reinforced sheet, and
- laminating the second fiber-reinforced sheet between the first fiber-reinforced sheet and the third fiber-reinforced sheet,
- wherein the first thermoplastic resin of the first prepreg and the second thermoplastic resin of the second prepreg are different thermoplastic resins.
