2 Observation of the Cross Section through SEM and SAM Measurement of the fiber orientation is one of the most important inspection items 2.1 Orientation of the Molding Cross to examine the shape and strength of the Sectionthrough SEM products[ll. The 3D fiber orientation has been measured by analyzing the elliptical marks of the cross section of the fiber from the photograph of the FRP. In these methods, it is not possible to obtain the azimuth and depression angle of the 3D
