摘要

Provided are a method for measuring the degree of orientation of fibers, a device for measuring the degree of orientation of fibers, and a program for controlling the device for measuring the degree of orientation of fibers, said method, device, and program involving consideration of the orientation of fibers in the thickness direction thereof in a simple and accurate manner. This method for measuring the degree of orientation of fibers is characterized by including a diffraction image acquisition step (step S1) in which a sample is irradiated with X-rays and an X-ray diffraction image is acquired, a peak angle calculation step (step S2) in which the angle (2θ)A of a peak derived from the crystal surface of graphite in the X-ray diffraction image is calculated, a correction coefficient calculation step (step S3) in which a correction coefficient δ for the thickness of the sample is calculated, an upper-limit calculation step (step S4) in which the upper limit (2θ)B of the peak of the crystal surface of the graphite is calculated, a diffraction sensitivity calculation step (step S6) in which the diffraction sensitivity IC(φ) of the peak derived from the crystal surface of the graphite is calculated, and a degree-of-orientation calculation step (step S7) in which the degree of orientation Sd(β) of fibers is calculated from the diffraction sensitivity IC(φ).
