抄録

<jats:p> The in-plane angle determined using an optical reflection microscope with an image analyzer is ambiguous, because the same elliptical image would be obtained for a fiber. A method of determining the three-dimensional (3D) fiber orientation distribution using the scanning acoustic microscopy (SAM) image of an elliptical mark and interference fringe is proposed. The interference fringe appearing in the composite in the direction of a fiber is observed by SAM. One can easily determine the in-plane angle without ambiguity by adopting this information of interference fringes. It is shown that this technique is effective for the determination of the 3D fiber orientation distribution in plaque and cylindrical composite parts. </jats:p>
