An abradable material (300) includes a matrix material (350) defining pockets of fluid (352). The abradable material also includes an outer surface (301) configured to be coupled to an interior surface (322) of a fan case (200) such that in response to the outer surface being coupled to the fan case, the abradable material is positioned circumferentially about an axis. The abradable material also includes an inner surface (302) defining a circumferential ridge (307,309,311;603) and a circumferential groove (303,305). |
