Document Type and Number:
WIPO Patent Application WO/2020/003608
Kind Code:
A1
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 (1), a filler (9) is arranged between a honeycomb core (2) and a first skin material (4) and/or between the honeycomb core (2) and a second skin material (6) so as to overlap the tip of an end of the honeycomb core (2). In a horizontal view, the filler (9) arranged between the honeycomb core (2) and the second skin material (6) protrudes outside the composite material (1) by a length equal to or less than a length of a portion thereof overlapping the tip of the end of the honeycomb core (2).
