  • Publication number: 20210001572
    Abstract: The present invention addresses the problem of providing a composite material that can prevent a strength reduction when fibers of a skin material are bent during curing of the composite material. In a composite material, a filler is arranged between a honeycomb core and a first skin material and/or between the honeycomb core and a second skin material so as to overlap the tip of an end of the honeycomb core. In a horizontal view, the filler arranged between the honeycomb core and the second skin material protrudes outside the composite material by a length equal to or less than a length of a portion thereof overlapping the tip of the end of the honeycomb core.
