HONEYCOMB CORE, HONEYCOMB SANDWICHING STRUCTURE, AND METHOD FOR PRODUCING HONEYCOMB CORE

摘要

This invention is concerning a honeycomb core configured to include carbon fiber having four or more different fiber directions, wherein, when a ribbon direction is set as an X axis direction, a cell width direction is set as a Y axis direction, and a direction that is orthogonal to the ribbon direction and the cell width direction is set as a Z axis direction, and a condition in which angles formed by the X axis direction and the respective fiber directions of the carbon fiber are set at -45°, 0°, 45°, and 90° is set as a reference condition, the respective fiber directions are rotated from the reference condition by a fixed rotation angle so that none of the fiber directions are parallel to the X axis direction.
