Abstract: A method for producing composite material components is provided with a process of laminating fiber-reinforced plastic tape. The method includes, at a plurality of sites from an attachment starting site to an attachment ending site of a first fiber-reinforced plastic tape, determining an attachment state of the first fiber-reinforced plastic tape during lamination of the fiber-reinforced plastic tape. The lamination is stopped when it is determined that the first fiber-reinforced plastic tape overlaps with a second fiber-reinforced plastic tape at a first site of the plurality of sites and that a gap exists between the first fiber-reinforced plastic tape and the second fiber-reinforced plastic tape at a second site of the plurality of sites. And, the lamination is continued when it is determined that the first fiber-reinforced plastic tape overlaps with the second fiber-reinforced plastic tape at all of the plurality of sites.

Abstract: An inspection method includes photographing an image by a camera mounted on a lamination head during a first fiber-reinforced plastic tape is attached by the lamination head while the lamination head moves, and calculating a gap amount between the first fiber-reinforced plastic tape and a second fiber-reinforced plastic tape on the basis of a first component of translational displacement in an optical axis direction of the camera which is a translational displacement of the lamination head during attachment of the first fiber-reinforced plastic tape, an in-plane second component of translational displacement which is perpendicular to the optical axis direction of the translational displacement, and the image.
